METHOD AND MACHINE FOR PRODUCING AN IMPRINTED CONTINUOUS WEB

TECHNICAL FIELD The present invention relates to a method associated with a machine arrangement in a machine for production of an imprinted continuous web of fiber material with a cellulose content, preferably a soft paper web, at which a wet web is fed through a roll nip together with at least one endless clothing, which, or of which at least one have the ability to receive and to transfer away water from the web and that the roll nip is a roll nip imprinting the web and that the wet web has a low enough dry solids content to allow remolding of fibers in the web during the passage through the roll nip, so that the web acquires a structure with areas with different density, after which the clothing or the clothings are transferred away from the web after the roll nip, the web is dried with at least an essentially maintained structure, and the dried, imprinted web is reeled up in a reel-up.

The present invention also relates to a machine arrangement in a machine for production of an imprinted continuous web of fiber material with a cellulose content, preferably a soft paper web, including at least one endless clothing which, or of which at least one, have the ability to receive and to transfer away water from a wet web, a press with a imprinting roll nip through which the clothing or the clothings are arranged to run together with the wet web for pressing said web, which web has a low enough dry solids content to allow remolding of fibers in the web during the passage through the roll nip, so that the web acquires a structure with areas with different density, devices to transfer away directly after the nip at least the clothing for receiving and transporting away the water from the web, a drying arrangement for drying the web with at least an essentially maintained structure, and a reel-up for reeling the dried, imprinted web during formation of a material reel.

PROBLEM PRESENTATION AND KNOWN TECHNIQUE

In conventional production of paper a continuous web is formed from a suspension of pulp with originally very high water content through dewatering on a wire. The wet web is then fed to a press section, comprising one or several wet presses with each at least one roll nip through which the web runs, and in which roll nip still more water mechanically is pressed out of the web. The web is then made to pass through a drying section in which remaining water is evaporated to a predetermined dry solids content for the web through a supply of heat. Finally, the web is reeled up into a finished material reel in a reel-up. At all web transfers between two consecutive machine sections the web must transferred from one drive section to the next over a larger or smaller distance. If the web at the time lacks support, for instance from a felt or another clothing said transfer is named an open draw. At the open draw the web must bear its own weight and hold for increased tensions caused by speed differences between the drive sections in question. The risk for web breakage with a subsequently and costly loss of production is high and therefore open draws should be avoided.

In later years press sections have been developed, which have done it possible to transfer the web from the forming section of the paper machine through all roll nips without any considerable tension on the wet paper web. Through the gradual increase of the dry solids content of the web, the strength of the web grows all trough the passage through the press section. Despite this fact the web still is sensitive for the increased tensions, which occurs at transfers between different sections of production. Furthermore, in a conventional wet press, a certain remoistering of the web always happens at the outlet of every roll nip, which deteriorates the obtained strength. A higher dry solids content in the wet web, already in an early stage of the production process, and a machine construction which is entirely free from transfers and open draws would conduce a reduced risk for web breakage, a higher web velocity and thereby a most essential increase in production with subsequent benefits for the paper industry, and also a higher bulk for soft paper and better quality in the final product.

Furthermore, in production of paper, board and cardboard, generally a very elongated drying section is used today which has a great number of drying cylinders and guide rolls that alternate with each other, around which the wet web runs during heating and evaporation of water. In production of soft paper, which has lower grammages and which for instance is used for production of household paper, paper towels and other hygiene products, a drying section is used instead that is comprising either a single drying cylinder with a relatively very large diameter and with a polished mantle surface which is steam heated from its inner side, i.e. a so called Yankee cylinder, on which the web bears for the essential drying of the web, or a combined machine which consists of both a Yankee cylinder and a number of common drying cylinders in succession. Also a through-blow dryer, TAD, can be used for said drying, but the TAD-dryer has several disadvantages, as a high and costly energy usage and a voluminous size. The large number of drying cylinders and, at the production of soft paper, the large diameter of the Yankee cylinder on up to 6 m gives the current paper machines a disadvantageous length. For the Yankee cylinder a considerable machine height is added as well. However, attempts have been made to reduce one or several of the problems mentioned above. For instance, from US-A-4,324,613 it is known that pressing of a wet web in a heat press at increased temperature and, simultaneously, at high pressure leads to several favorable effects, e.g., a considerably increased dewatering speed and thereby a shortened drying section. The term "heat press" which is used in the present context and which constitutes an integration between a press and a drying arrangement is by many improperly named "impulse dryer". The patent describes a roll nip, heated from the outside, which is formed between two towards each other movable cylindrical rolls of which one roll have a high surface temperature. The combination of high temperature and, simultaneously, high-pressure gives a high thermal flow to the web which results in a high dewatering speed. The good dewatering result most likely have reference to the considerable steam generation at the roll nip, which helps to squeeze remaining liquid out of the web, that the increased temperature gives a reduced water viscosity and/or that the water which during the impact of the roll nip pressure attains a temperature in over 100 °C, rapidly evaporates when the pressure cease to exist when the web leaves the roll nip.

However, in a conventional roll nip the dwell time for the paper web is too short in order to get any real benefits from the favorable effects of the heat pressing. However, from the patent US 5.393.384 it is known a paper machine for production of soft paper, in which one off the embodiments shows a shoe press with a press shoe, which act against a heated drying cylinder. Since the roll nip of the shoe press is extended to 20 to 30 cm approximately, the heat treatment during pressure becomes substantially extended.

Furthermore, when producing soft paper there is a frequent wish that the relationship between the volume and the weight in the paper, i.e. the bulk, shall be substantially higher than for other papers, when paper with high bulk obtains a desirable combination of both softness and high power of absorption.

It has been done attempts to manufacture soft paper with substantially increased bulk. For instance, the patent US-A-3, 806,406 describes a method and a device for forming of a soft paper web with high bulk. A wet web is fed on a felt through a roll nip comprising a press roll and a heated Yankee cylinder. Because the pressing of the web results in a, for soft paper, unwanted low bulk, it has been tried to minimize the web surfaces which are exposed to pressure. Therefore, the mantle surface of the Yankee cylinder comprises alternately raised and lowered surface portions, which constitutes a relief pattern for placing against the web. Substantially, only those parts of the web which are in contact with the raised surface portions are compressed, while the parts situated in between are left relatively unaffected. Substantially, the entire drying is done thermally through the supply of heat from the Yankee cylinder, during which the soft paper web is held in a fixed mode in relation to the surface portions. Thereby the web acquires a certain texture, i.e. a determined pattern of compressed and uncompressed surface portions, which surface portions equals the relief pattern of the mantle surface in question. Thereby the web also obtains the desirable and increased bulk.

However, the Yankee cylinder has some essential disadvantages. One problem, which is mentioned above, is that the Yankee cylinder has a large diameter and therefore it is very voluminous. Another problem is that when using a Yankee cylinder it is difficult to achieve those very high temperatures, which are used in heat pressing. Despite the fact that the steam within the drum can have a very high temperature, the drum mantle surface only reaches 95 °C to 100 °C approximately, and therefore in most cases still more warmth from external drying devices, for instance by through drying, must be additionally supplied to the drying process, either before or after the Yankee cylinder. The mantle of the Yankee cylinder must, in order to be able to resist both the internal steam pressure and the external pressure against the mantle surface, have a considerable thickness in between approximately 50 to 100 mm. Said thickness, together with the large the diameter, causes a large mass of material, which must be heated up and which effectively blocks the thermal flow from of the drum interior to its mantle surface. Another problem is that it is difficult to keep the geometrical shape of the roll in the cross machine direction on an account of difficulties to maintain the same temperature along the mantle surface of the roll and on the gables. Since the mantle surface and the gables can not expand freely and independently of each other, large tensions occurs between these, why the mantle surface becomes arc-shaped, outwardly or inwardly, across the machine direction. Since the inner parts of the roll also will absorb a part of the supplied heat energy, the described construction will become very energy consuming with high fuel costs as a consequence.

From US-A-5, 830,316 it is known a method and a device for production of an imprinted soft paper web, at which an imprinted wet press nip is transporting a wet web carried by a endless clothing with ability to receive and to transfer away water from the web. The web is so wet that it allows remolding of fibers in the web at the passage through the wet press nip, why the web receives an imprinted structure. The out of the wet press still wet web is then moved with the received structure substantially maintained to a drying section in which the web is dried, which drying section can comprise a through-blow dryer and an Yankee cylinder, from the latter of which the dried web must be creped away, which causes an unavoidable open draw, before the web can be reeled up The design has several disadvantages, the wet press tends to remoisten the web, and the heat pressing technique is not used and opens draws still remains

Another process of heat pressing of a soft paper web is described in the patent US 5.556.511. A soft paper web is moved together with a felt for absorption of liquid from the web through a press zone, which web is heated before or inside the press zone The sudden expansion of the steam in the web when said web leaves the press zone is considered to cause a delamination, which improves the volume and the softness in the web, i e. increases the bulk of the web Still more warmth can be supplied to the web after that the web leaves the press zone by means of drying devices arranged therefore Since the drying cylinder has a smooth mantle surface, at which surface the web easily sticks; the dried web is detached by creping from the drying cylinder by means of a creping blade. A creped web, which is substantially dry at the creping, does not obtain the favorable rewetting characteristics as a web still in a wet condition does when imprinted, but the creped web looses the favorable structure received at the creping after it has absorbed water. Also, another and most essential disadvantage is that yet one unavoidable open draw is created from the creping blade to the reel-up, across which the web must be transferred before any final reeling to a completed reel can be done

As will be understood a paper machine comprising several separate parts of one or several wet presses, a number of drying cylinders of different sizes, a reel-up with a relatively large surface winding drum and above that a number of open draws or transfers between said machine sections obtains an unfavorable length, an impaired paper grade and a considerable risk for web breakage and thereby a lower production These disadvantages, together with increased requirements for higher bulk and lower energy usage during the drying have led to wishes about a shorter, faster and more production safe machine design.

THE PURPOSE AND CHARACTERISTICS OF THE INVENTION

The object of the present invention is to achieve a machine arrangement in a machine for production of a continuous web, which machine arrangement substantially reduces the total machine length, eliminates the remaining transfers and open draws for the web between the press section and the completed the jumbo roll, and at least substantially reduces the other problems mentioned above, as among others remoistering problems, high heating costs and poor rewetting characteristics for the acquired bulk, at which the favorable effects of both the heat pressing and the imprinting can be used in a better manner than earlier.

The method according to the invention is characterized by that the web is pressed and dried in a heat press, which have at least one heat transfer device with a heatable surface, which is heated up by a heating device, and which surface is in contact with the web, which heatable surface runs through the roll nip together with at least one clothing which feeds the web so that the web is enclosed between the clothing and the heatable surface and which heat press is integrated with the reel-up.

The machine arrangement according to the invention is characterized by that the press and the drying arrangement are integrated with each other to form a heat press, which has at least one heat transfer device with one heatable surface which is arranged to be heated by a heating device and which surface is arranged to bear against the web and going through the roll nip together with at least one clothing which is arranged to carry the web and enclose the web between the clothing and the heatable surface and which heat press is integrated with the reel-up for forming of said machine arrangement.

With the present invention is achieved that

- the machine arrangement becomes entirely free from open draws and transfers from the press section to the finished material reel,

- that the machine arrangement becomes very compact, i.e. that a substantially shortened total machine length is reached compared with existing machine designs, together with

- that expensive and needlessly energy consuming machine sections, as the Yankee cylinder and the long conventional drying section with several drying cylinders after each other is eliminated, why the production becomes both faster and more energy- saving, - that a crepe free web with especially favorable properties as higher bulk is achieved, which bulk remains after rewetting of the web with qualities similar of those of the TAD-dryer, but a lot cheaper.

DESCRIPTION OF AN EMBODIMENT

Figure 1 shows schematically and in side view parts of a machine arrangement in a paper machine for production of a continuous web 1 of fiber material with a cellulose content, preferably a soft paper web, according to a first embodiment of the invention. The machine arrangement comprises a reel-up 2 for reeling the web 1 on reeling drums 3 into completed material reels 4, preferably rolls of soft paper. The reel-up 2 comprises two identical, elongated and aloof from each other arranged parallel stand members 5, of which merely one is shown, for supporting the reeling drum 3 at its end parts; one surface winding drum 6 arranged between the stand members 5 at the upstream end of the reel-up 2, seen in the feed direction of the web 1, which embodiment, shown in figure 1, especially comprises a surface winding drum 6 with a smooth mantle surface 7, over which mantle surface 7 the web 1 is arranged to run to one of the reeling drums 3, or said material reel 4 being formed thereon. The described reel-up 2 is generally designated both cylinder reel-up or reel-up, why the phrase "reel-up" have been chosen for this description. The surface winding drum 6 is rotatably journalled at two bearing houses 8, which are located one at each of he stand members 5. A drive motor (not shown) gives the surface winding drum 6 a peripheral speed, which equals the forward feeding speed of the web 1. The diameter of the surface winding drum 6 is approximately in the region of 1,0 to 3,0 m.

Further, the reel-up 2 has two systems for maintaining a continuous production of reeled web 1, namely a primary system 9 for receipt of new, empty reeling drums 3 and a secondary system 10 for taking over the reeling drum 3 from the primary system 9 with the material reel 4 commenced thereon for a continued reeling to a finished material reel 4. The primary system 9 is arranged to transfer the reeling drum 3 along the periphery of the surface winding drum 6 down to the horizontal stand members 5, where the secondary system 10 takes control of the reeling.

The primary system 9 comprises a pair of elongated primary arms 11 which are parallel with each other, which are pivotably arranged at each stand member 5 at the bearing house 8 of the surface winding drum 6 by means of two actuators 12. The primary arms 11 are shown in figure 1 and 2 with certain parts removed in order to better visualize hidden details of the machine arrangement. A supply 13 of empty reeling drums 3 is arranged at the upstream end of the reel-up 2 and above the surface winding drum 6, from which drum supply 13 the primary arms 11, in the shown embodiment, is arranged to transfer an empty reeling drum 3 for placing against the web 1 which is running over the driven surface winding drum 6 for the starting of the web 1 reeling, when the growing material reel 4 located downstream, approaches a predetermined size.

Alternately, in a not shown embodiment, a pair of lowering arms is arranged instead at the roll supply 13, by which lowering arms the reeling drum 3 is arranged to be transferred to the primary arms 11 before said placing against the surface winding drum 6. The secondary system 10 comprises, in the embodiments shown in figures 1 and 2, a pair of secondary carriages 14, which are arranged linearly displaceable along the outer sides of the stand members 5, determined by the increase in diameter of the material reel 4. Instead of secondary carriages 14 the secondary system 10 can comprise a pair of secondary arms (not shown), which then are pivotally arranged, one at each of the stand members 5 for turning in time with said diameter increase of the material reel 4.

The secondary carriages 14, which are reversed in relation to each other and the stand members 5 comprises each a vertical platform 15, which have bearings mounted on the side which is turned towards the stand member 5 for cooperation with tracks 16 which are arranged at the stand member 5. Each secondary carriage 14 further comprises an actuator 17 for enabling the linear to and fro movements of the secondary carriage 14. The actuator 17, which for instance can consist of a hydraulic or pneumatic cylinder, is attached at the secondary carriage 14 with one of its end parts and at the stand member 5 with its other end part. The movements of the two secondary carriages 14 along the tracks 16 are, as well as the primary arms 11, synchronized with each other. Each secondary carriage 14 comprises a maneuverable gripper 18 for receiving and for seizure of the reeling drum 3, which gripper 18 is arranged at the exterior of the platform 15. Each gripper 18 comprises a locking arm 19 and a pressing arm 20 arranged downstream in relation to the locking arm 19, which arms 19, 20 are arranged pivotally at the secondary carriage 14 and which arms 19, 20 each have an actuator 21, 22. The pressing arm 20 is arranged to press against the end part of the reeling drum 3 for maintaining a predetermined linear pressure in the nip between the surface winding drum 6 and the material reel 4, also designated below as the first roll nip 23, during the size increase of the latter. Along the upper edge of each of the stand members 5 is a horizontal rail 24 rigidly mounted. The two rails 24, which are parallel, are intended to support the reeling drum 3 at its end parts during the movement of the secondary carriage 14 in direction from the surface winding drum 6. Alternately, the reeling drum 3 can instead rest on one separate rail element (not shown) arranged horizontally at each upper edge of said secondary carriage 14 during the actual reeling in the secondary system 10, in order to be transferred to the rails 24 for forwarding out of the reel-up 2 when the material reel 4 is completed. A center drive device (not shown) can be mounted on one of the secondary carriages 14 for driving of the reeling drum 3 which is held in the grippers 18, and thereby the material reel 4 being under construction. Thus the center drive device is linearly displaceable together with said secondary carriage 14 in a direction parallel with the rails 24. The primary system 9 can in the same manner also be equipped with a center drive device (not shown) for an initial acceleration and thereafter for maintaining of the same peripheral speed at the reeling drum 3 as at the surface winding drum 6, in which unwanted frictional forces in the roll nip 23 is avoided.

In the corresponding manner each of the primary arms 11 comprises a maneuverable gripper 25 for the seizure and holding of each new reeling drum 3 during its transportation downwards into contact with the surface winding drum 6 and during its continued movement along the periphery of the surface winding drum 6, further down to the rails 24 of the stand members 5, or said rail elements mentioned above. The gripper 25 is arranged at a primary carriage 26, which is linearly movable along the primary arm 11 by means of an actuator 27, which linear movement is determined of the increase in diameter of the growing material reel 4 on the reeling drum 3 during the initial reeling in the primary system 9 and of the necessary change of the gripper 25 position along the primary arm 11 at the movement along the surface winding drum 6. As at each of the secondary grippers 18, each primary gripper 25 comprises a locking arm 28 and a pressing arm 29, of which at least the locking arm 28 is maneuverable by means of an actuator (not shown) for a opening or a locking movement of the gripper 25.

The machine arrangement further comprises a press 30 which is arranged in proximity to, and upstream of the surface winding drum 6, a drying arrangement 31 for drying of the web 1, which press 30 and which drying arrangement 31 are integrated with each other into a heat press 50 with a nip 34 between them, and at least one clothing, which leads the web 1 to the roll nip 34. In order to achieve wet embossing of the web 1, there should be at least one imprinted surface, which lies towards the web 1. The imprinted surface can in different embodiments consist of a "pattern carrier", as an embossing wire 32 or a process belt, or an imprinted surface on the drying arrangement 31, comprising the mantle surface 7 of the surface winding drum 6 or the surface of the loose sleeve 45, or their combination. In this context "pattern carrier" concerns a device, which is arranged to give a still wet web, i.e. before the essential drying of the web has taken place, a certain texture, i.e. a pattern imprinting, which gives a determined embossing pattern of compressed and not compressed surface portions, which surface portions equals the actual pattern of the pattern carrier in question. The web thereby also receives the desirable, increased and durable bulk, since a pattern imprinting of a wet web, and a thereafter undertaken drying without the received structure being destroyed of the so embossed web, achieves said high bulk, as the structure simultaneously remains even after that the web has absorbed water. Thus, with "wet web" means that the web have a low enough dry solids content in order to allow remolding of fibers in the web at the passage through the roll nip, so that the web acquires a structure with areas of different density.

The press 30 is included expressly, but not exclusively, in a paper machine for producing of paper with low grammage, i.e. a soft paper web. However, the paper machine can be designed for producing of any other paper grades whatever. The press 30 comprises a press device 33 for pressing in cooperation with the surface winding drum 6 by way of a roll nip 34 which is formed against the upstream side of the surface winding drum 6, also designated the second roll nip 34 below, an endless clothing in order to receive and to transfer away liquid from the web 1 in a floating form or in the form of gas out of said roll nip 34. The clothing usually consists of a press felt 35, that has a substantially smooth surface, but can also consist of an embossing wire 32, which either is permeable with continuous openings and possibly cavities located or extending between these openings, or impermeably with cavities with a suitable and finite depth, shape and extension. Said cavities exist on the side that is closest to the web 1. In certain embodiments of the invention, described closer below, is the clothing of the press 30 (see for instance figure 7), in the form of a press felt 35, for receiving and transporting away liquid from the web 1 also arranged for conveying of this against the press device 33 and through the roll nip 34, which press felt 35 then is in direct contact with the web 1, why the above-described press felt 35, in this context, also to some extent have a pattern carrying surface, when the openings and/or the cavities causes a certain impression in the form of an imprinted pattern in the web 1, i.e. the web receives a certain texture, which imprint increases the web 1 bulk. Instead of a permeable or impermeable embossing wire 32 can an open, or a closed wire which has a sealing layer on the side turned away from the web 1, be used.

The drying arrangement 31 comprises a movable heat transfer device 6, 45, 54, that has a heatable surface 7, 51, 59 for transfer of warmth to the web 1 for drying of this to a predetermined dry solids content, and at least one heating device 38 for heating of the movable heat transfer device to a desired operating temperature at startup and thereafter for a continuous heating during operation for maintaining of this operating temperature. The web can be arranged to be preheated before the nip 34 by a suitable heating apparatus of different types, not shown. In the embodiment shown in figure 1, the mantle surface 7 of the surface winding drum 6 constitutes said heatable surface. Additional heating devices 38, which is indicated in figure 1 and 2 with dashed lines, can be arranged along the periphery of the surface winding drum 6 for after-drying of the web 1. Each heating device 38 is firmly or movably arranged, e.g. oscillating, at a predetermined position, or in relation to the roll nip 34 within a predetermined interval of space. If there are more than one heating device 38 these preferably are arranged on each side of the roll nip 34 against the press device 33. The heat transfer is thus arranged to happen foremost at the passage of the web 1 through the roll nip 34, but also during the rest of the distance, at which the web 1 is arranged to follow and cooperate with the heat transfer device, a heat transfer, i.e. after-drying of the web 1, occurs. At the considerable heating in the roll nip 34, during the simultaneously applied high pressure, a swift and intense evaporation of water is obtained from the web 1, at which the dry solids content of the web 1 increases most substantially, in order to achieve the wished dry solids content for the web 1 in question at the after-drying later, which is done free from external pressure during the transport towards the completing reeling on the reeling drum 3. The linear pressure in the nip is approximately within the interval of 200 - 800 KN/m, preferably within the interval of approximately 300 - 600 KN/m and the temperature is within the interval of approximately 200 °C- 300 °C, preferably at least 150 °C. At the point of reeling on the reeling drum 3 the web 1 have achieved a desired dry solids content on up to approximately 95 %. Any suitable heating device 38 can be used, even if an induction heater currently is preferred. Examples of other heating devices 38 are electric and electro-magnetic heaters, infra heaters, laser heaters and gas burners. The heating devices 38 can be arranged within one or several combustion chambers 39, see figure 1 and 2, which are arranged along one sector of the surface winding drum 6 for each of said combustion chambers 39 and then suitably in front of or in proximity to the roll nip 34 against the press device 33. At the embodiments shown in the figure 1 and 2 a hood 40 is arranged at the upper side of the surface winding drum 6, which hood 40 enclose a larger part of the periphery of the surface winding drum 6 between said first and second roll nips 23, 34. The hood 40, which can consist of a ventilation cover, is arranged to enclose one or several heating devices 38 for preventing energy loss and for evacuation of the steam emitted at the drying. The clothing or the clothings, in the form of embossing wires 32 and press felts 35, which are arranged to run downstream to the press device 33 and further through the roll nip 34 are arranged to run in a closed loop across a number of rotatably journalled guide rolls 41, 42, which are arranged upstream of the surface winding drum 6 in order to turn around the press device 33 and from this run in a direction backwards from the reel-up 2.

Each pattern carrying surface comprises, in relation to the surface of the web 1, imprinting elements 44 in the form of elevations, depressions and/or cavities which are arranged in a randomly or predetermined pattern on the side of the pattern carrying surface which is turned towards the web 1 for generation of an impression in the form of an imprinted pattern imprint in the web 1. Depending on if one or two pattern carrying surfaces are arranged to follow the web 1 through the roll nip 34 against the press device 33, i.e. if pattern carrying surfaces are arranged on one or on both sides of the web 1, the pattern imprinting becomes single-sided or double-sided. Pattern carrying surfaces can comprise of one of several alternative designs: for instance an embossing wire 32 with imprinting elements in the form of woven wire threads forming elevations and depressions in relation to the surface of the web, a process belt 36 with imprinting elements in the form of elevations and/or cavities of suitable size, shape and extension, or a relief patterned mantle surface 7 (see especially the figures 4 and 5) which enclose the surface winding drum 6 and which imprinting elements 44 consists of geometrical figures with suitable surface or shape. However, the surface winding drum 6 can also comprise a heatable cylindrical, loose sleeve 45, see for instance figure 5, which enclose the surface winding drum 6 axially, and which sleeve 45 can have an imprinted mantle surface 7 in the same manner as described for said surface winding drum 6.

The dimensions of the imprinting elements, seen in a cross-section through the surface winding drum, lies within an interval between approximately 0,1 to approximately 2,0 mm for the height on a specific imprinting element, i.e. the difference in radius between the top surface of the imprinting elements and the bottom surface of the cavities. The largest extension for a specific imprinting element in any direction along the mantle surface lies within an interval of approximately 0,5 to approximately 5 mm. Compared with a corresponding unimprinted web, the part of the surface of the imprinted web which is in direct contact with the top surfaces of the imprinting elements by way of the roll nip against the press device amounts to in between 20-50% approximately. For closer exemplification of the imprint and the imprinting elements, see the Swedish patent applications of same applicant which applications were handed in at the same date with the titles "Press" and "Drying section", respectively.

ALTERNATIVE EMBODIMENTS In the first embodiment shown in figure 1 of a machine arrangement according to the invention comprising a heat press 50 with heating devices 38 and press 30 integrated with a reel-up 2, which reel-up 2 especially comprises a surface winding drum 6 with smooth mantle surface 7, the press 30 consists of a roll press and the press device 33 consists of a cylindrical, smooth press roll for creating of a conventional roll nip 34. Through the roll nip 34, heated by said heating device 38 and imprinting the web 1, the press felt 35, an embossing wire 32 and the web 1 are arranged to run together in contact with, for the press felt 35, the cylindrical roll 33 and for the web 1 against the hot surface winding drum 6, with the embossing wire 32 arranged in between the press felt 35 and the web 1 for single-sided imprinting of the web 1. The smooth surface of the surface winding drum 6 can be doctored, the web 1 follows the smoothest surface after the roll nip 34, i.e. the smooth mantle surface 7 of the surface winding drum 6, which constitutes two favorable advantages with the embodiment shown in figure 1, free from web transfer problem.

In the second embodiment shown in figure 2 of the machine arrangement according to the invention, the press 30 instead constitutes of a shoe press with a extended roll nip 34 and the press device 33 of a shoe press roll which comprises a press shoe 46 and an impermeable flexible mantle 47 and the surface winding drum 6 is axially enclosed by a loose sleeve 45 with smooth mantle surface 51. The mantle 47 is rigidly mounted at rotatable peripheral gable parts 48 of the shoe press roll 33. The press shoe 46 have a concave surface 49, over which the mantle 47, the press felt 35, the embossing wire 32 and the web 1 are arranged to run together under sliding contact against the press shoe 46 for the mantle 47, under contact against the surface winding drum 6 which have a smooth mantle surface 7 for the web 1, and with the press felt 35 and the embossing wire 32 between the mantle 47 and the web 1 for single-sided embossing of the web 1. The concave surface 49 is thereby in pressure generating cooperation with the surface winding drum 6 by means of actuators (shown with a schematic arrow) for forming of the extended roll nip 34. The web 1 is separated from the felt 35 and the embossing wire 32, respectively, after the outlet from the roll nip 34 in order to bear on and follow the sleeve 45 around a predetermined part of its mantle surface 51 instead. In the detail view shown in figure 3 of the machine arrangement according to figure 2, it is apparent that the heatable sleeve 45 is loosely arranged in relation to the surface winding drum 6 which sleeve 45 is replaceable, form stable and heatable from its outside 51 and which sleeve 45 is arranged, except in the roll nip 34, enclosing with a radial play 52 at least the entire operative axial portion of the surface winding drum 6 of the roll nip 34 and so arranged that it can expand freely in relation to the surface winding drum 6 at said heating before the roll nip 34 without thereby arising unfavorable tensions in the sleeve 45. The sleeve 45 has a circular cross-section with an interior 53, which is arranged to be forced into contact with the surface winding drum 6 within the zone for the roll nip 34. The outside 51 constitutes the mantle surface mentioned above, around which the web follows in contact from the inlet of the roll nip 34 and further to the reeling drum 3 for reeling thereon. During operation the surface winding drum 6 is arranged to press the sleeve 45 firmly against the press device 33 to create a large enough friction force between the surface winding drum 6 and the sleeve 45 so that the sleeve 45 is rotated in the roll nip 34 by the driven surface winding drum 6 and at the same speed as said surface winding drum 6. During operation the sleeve 45 is arranged to rotate about its own axis of rotation, which is eccentrically located in relation to the axis of rotation of the surface winding drum 6. Furthermore, in the machine arrangement according to the embodiment displayed in figure 3 is shown a felt 35, an embossing wire 32 which transports a web 1 through the heated roll nip 34 imprinting the web 1 and a reeling drum 3 in which a material reel 4 is under reeling against the mantle surface 51 of the sleeve 45. At said embodiment the press device 33 constitutes of a shoe press roll, but can instead consist of a press roll (see figure 1) which also goes for all other feasible embodiments of the invention. The linear load, i.e. the nip pressure in the first roll nip 23 located downstream, between the mantle surface 51 of the sleeve 45 and the reeling drum 3 with the material reel 4 being reeled on said reeling drum 3, is so much lower than the nip pressure in the roll nip 34 located upstream between the press device 33 and the sleeve 45 on the substantially opposed side of the sleeve 45 that said friction force for driving of the sleeve 45 is free of negative effects from it.

Generally, for the invention goes that the control of the nip pressure for the material reel 4 growing on the reeling drum 3 in the first roll nip 23 located downstream of the surface winding drum 6, is arranged to be performed through a cooperation between the actuators of the primary system 9 during the initial reeling, but, after that the secondary system 10 has taken over the growing material reel 4, be guided by the actuators of the secondary system 10 in cooperation. Respective pressing arm 20, 29 of the systems 9, 10 are thereby arranged to press against the end parts of the reeling drum 3 for maintaining of a desired and controllable nip pressure during the entire increase in size of the material reel 4.

The reeling drum 3 is for instance driven by the above mentioned separate center drive device belonging to the primary system 9 for the initial acceleration of the reeling drum 3 and thereafter under maintaining of the same peripheral speed at the material reel 4 being reeled as the peripheral speed at the surface winding drum 6 in question, at which unwanted frictional forces and the inverse linear pressure, in relation to the second roll nip 34, which is caused by the contact of the reeling drum 3 against the sleeve 45 is held within a predetermined and allowed ratio for maintaining of a correct linear pressure and thereby also the wished friction between said sleeve 45 and the press device 33 for driving of the sleeve 45. The sleeve 45 has a sufficient wall thickness to resist the tensions which occurs in the sleeve 45 in and on a account of the two roll nips 23, 34, so that the sleeve 45 maintains both its straightness cross machine and its radius all around, i.e. the wall thickness of the sleeve 45 is so chosen that the sleeve 45 is free from ovalities and axial deformations.

In figure 4 the third embodiment of the invention is shown, the machine arrangement comprises a shoe press roll 33 over which a felt 35 is arranged to run for receiving and transporting water away from a web 1, an embossing wire 32, a relief patterned and heated surface winding drum 6, which relief pattern constitutes a second movable pattern carrier for creating of a heated roll nip 34 which imprints the web 1 on both sides, and a reeling drum 3 on which a material reel 4 is reeled against the imprinted mantle surface 7 of the surface winding drum 6.

The fourth embodiment of the invention shown in figure 5 differ from the one shown in figure 4, since it especially comprises a loose relief patterned and heated sleeve 45, which relief pattern constitutes a second pattern carrier for creating of a roll nip 34 imprinting the web 1 on both sides.

The embodiments of the invention shown in figures 6 and 7 differ from those embodiments shown in figure 4 and 5, in that the web 1 is arranged to follow a smooth clothing, for instance in the form of a press felt 35, in to the second roll nip 34 between the press device 33 and the surface winding drum 6, or between the press device 33 and the sleeve 45 for a single-sided imprinting of the web 1. In the embodiments of the invention shown in figures 8 to 11 the machine arrangement comprises a heatable, imprinted and endless pattern carrier, which for instance can comprise a belt 54, or similar, which pattern carrier is arranged in a loop around the surface winding drum 6 or the sleeve 45 enclosing the surface winding drum 6 and one or several guide rolls 58, in which the surface winding drum 6 and the sleeve 45 has a smooth mantle surface 7. The embodiments of the invention shown in figures 8 - 11 differ with reference to the number of movable pattern carriers that is arranged for through feed of the heated roll nip 34 for either a single-sided or double-sided pattern imprinting of the web 1, and the presence of a sleeve 45 around the surface winding drum 6. Fig. 9, 10 comprises an embossing wire 32 and can achieve a single-sided imprinting if the belt have a smooth surface or a double-sided if the belt 54 is imprinted. If the belt 54 is impermeable the spray nozzle 56 arranged within the web loop in the figures 8 - 11 is arranged outside said web loop instead.

A blowing apparatus 55 is arranged in near proximity to and downstream of the outlet from the mentioned first roll nip 23 against the growing material reel 4 (in the embodiment comprising a surface winding drum 6, see figure 1), at a surface winding drum 6 enclosed by a sleeve 45, see figure 2, and at the embodiment comprising a pattern carrier in the form of an endless belt 54 against which the reeling of the web 1 is arranged to be performed supported by a portion of the belt 54, see figure 8, which blowing apparatus 55 comprises one or several spray nozzles 56 for compressed air, so called air-knives, for considerable air blowing against the web 1 for facilitating the releasing of the web 1 from the supporting surface in question, which can consist of the mantle surface 7 of the surface winding drum 6 as described above, the embossing wire 32 or the sleeve 45, and for cleaning of the same. At the embodiment with a permeable belt, see the figures 8 - 11. At the embodiment with an impermeably belt (which is not shown) the blowing apparatus 55 and a possible doctor blade is instead arranged on the outside of the web loop 54. However, at temperatures on the supporting surface from 250°C and upward it is known that the web 1 loosens easily from the supporting surface. This is considered to be due to the high dry solids content obtained by the heat pressing of the thereby not so adhesive web 1 and the steam pressure which occurs on the side of the web 1 which is turned towards the surface winding drum 6. If so desired, the air jet can consist of or cooperate with the hot gases from a gas burner, or similar. All fibers that have been stuck to the supporting surface will immediately be burnt to ashes and transferred away by the jet of gas. In addition, the heating of the supporting surface by means of the hot gases reduces the need of additional heating devices for the heating of the web. For said cleaning can, for instance, brushes be used also (not shown).

With the above-described invention is thus a machine arrangement reached which comprises a combination of a reel-up 2 and a heat press 50 for producing of a continuous web 1 with high bulk of fiber material with cellulose content for reeling of an imprinted paper web 1 directly against a drying cylinder, which also constitutes the surface winding drum 6 of the reel-up 2, without the web 1 being creped from the drying cylinder 6. The web 1 runs free of open draws during the reeling and a paper machine with a very compact design is achieved, when the need of a Yankee cylinder is removed. The resulting product comprises an uncreped paper web 1 with especially favorable properties mentioned above.

All the above-mentioned actuators can for instance comprise hydraulic or pneumatic cylinders. Finally, for ensuring the transfer of the web 1 to the reeling drum 3, a gluing device 57 for application of an adhesive on either the web 1 or the reeling drum 3 is arranged before the roll nip 23 against the reeling drum 3.
