Description

TECHNICAL AREA

The invention relates to the field of further processing of precursors (in particular of printed products in the context of print finishing). It relates to a method and an apparatus for producing collections of printed products.

The invention further relates to a device for carrying out the method.

BACKGROUND OF THE INVENTION

The term "direct mailing" has long been known for activities in which advertising leaflets, brochures, flyers, printed sheets, samples and the like, as they were often used for advertising purposes as supplements of a newspaper or magazine attached (plugged), by several advertisers be collected in order to make a variety of collections, each containing a print product from a variety of advertisers and in the form of a small stack to the recipient (eg households) are delivered and distributed.

In order to handle the individual stack-like collections of printed products during transport and distribution better, it is advantageous to take measures to hold together the individual stacks.

Methods and apparatus are known in the art for holding stacked printed products or related products together by wrapping with other cohesive elements.

The DE 41 31 277 C1 shows a method and a device suitable for this, with which a packaged goods can be combined with a special packaging blank. Shown is a device in which a packaged product passes from a first feed device to a second feed device. The second feed device has a lower belt, which is guided on one side over a roller. With a pressure device, which has a pinch roller and a guide element, an articulation of the package blank is to be effected on the roller to lead the package blank in different ways to the packaged goods. The packaging blank is handled in this process to the packaged goods, the apex area of the turnaround is not specially processed. In order to prevent that the folded packaging blank unfolds again due to internal tensions, therefore, only packaging blank with certain properties (eg with regard to the inherent rigidity and the basis weight) can be used.

The EP 0952006 A2 shows a process for the production of printed mail, a wrapper, a device for the production of the wrapper as well as methods for the production of the wrapper. The application discloses the packaging of printed items by a perfect wrapping with a specially cut as a packaging material sheet of paper or plastic, so a specific packaging product. Such a single sheet is to be cut for example with a cutting unit and then folded, with folded edges folded edges can be connected to each other by means of adhesive.

The WO 2012/084494 A2 shows a method for assembling a stack of loosely stacked precursors, the assembling of such precursors and an apparatus for producing such compilations. For this purpose, in a first step, the stack to be assembled from loosely superposed precursors is provided and in a second step a connecting element is attached to a stacking edge of the stack such that it overlaps the two outer precursors of the stack in an adhesive manner. This method provides a secure packaging for a variety of applications, but requires special fasteners to be glued.

The not pre-published European Patent Application No. 15001321.7 was published on 05.05.2015 on behalf of Ferag AG and shows a device for the production of collections from a variety of different printed products. In each case, a part of the printed products is used as a packaging element, in which the other printed products are taken. On In this way, handle units can be produced which can be easily removed from a distributor by hand from a transport container. In contrast to previously known methods for producing such collections, this method does not require any special additional packaging means, such as films or tapes. As a result, the costs of producing collections can be reduced and the amount of waste produced can be reduced. The said patent application shows several methods and devices for the production of such collections. An embodiment of a suitable handling device has a brush roll with bristles bent in the direction of rotation, which deflects a section of a packaging element, which was previously brought partially under an intermediate stack (eg from publications), approximately at right angles to the top. This packaging section is bent back in a subsequent step on the intermediate stack as soon as the packaging element and the intermediate stack enter the space between two conveyor belts. Another handling device shown in the aforementioned application has rod-shaped drivers, which are rotated about an axis of rotation oriented transversely to the direction of movement of the unit of intermediate stack and packaging element. These drivers additionally perform an oscillating movement transversely to the conveying direction, which may require a relatively complex and / or maintenance-intensive mechanism or control. Both transhipment devices shown in the aforementioned application are suitable for a large number of transhipment products and intermediate stacks. However, with certain groups of envelope products and intermediate stacks - especially with envelope products with relative high inherent rigidity - the turnaround will be unstable, ie tend to unwanted unfolding.

The EP 2462043 B1 shows a folding unit and a method for folding a flake stream of products to allow folding directly at the exit of a rotary printing press. For this purpose, the products should be folded so that each of the trailing products are partially arranged in the leading product. When folding the products should therefore take a product in each case the trailing with and it should be folded in the direction of that side, which is touched flat by the subsequent product. This has the advantage, among other things, that shingled streams can be processed directly from the exit of the rotary printing press, without relocating them beforehand.

The WO 2008/074325 A1 shows a method for wrapping a stack of sheets, brochures or the like, in which the stacks are transported at a distance in a row on a transport path. By means of a special swivel wheel, a wrapping sheet is withdrawn from a stored sheet supply and positioned vertically in a gap between two successive stacks. Subsequently, the swivel wheel provides means that fold the sheet around the stack moving past. The complicated movement of the swivel wheel prevents a high processing speed of the stack.

PRESENTATION OF THE INVENTION

The prior art methods and devices allow the wrapping or wrapping of precursors to hold them together. However, in the products or collections made by these processes, additives such as e.g. Adhesive dots necessary to ensure a sufficiently durable wrapping by the respective holding elements. This is e.g. then the case when relatively thick stacks of printed products are to be turned over. Likewise, in the case of products produced by these methods, the peak area of the folded cohesion element is often irregularly deformed. Thus, this area can be e.g. not be straight or have bumps. This is particularly problematic when a printed product is used as a cohesive element, as this is critically affected by its appearance. It is therefore an object of the invention to provide a simple method which allows for a turnover of first precursors with second precursors and efficiently prevents re-deployment of the handled product as compared to the prior art methods, as well as a cohesive element at a predefined location reverses in an advantageous and reproducible manner.

It is a further object of the invention to provide a device with which such a method can be carried out.

These and other objects are achieved by claims 1 and 17. Embodiments of the invention will become apparent from the dependent claims.

• Bereitstellen eines zweiten Vorprodukts, das einen Umschlagefalz mit einer Falzinnenseite aufweist;
• Fördern des zweiten Vorprodukts in eine Einschiebestellung, in der das zweite Vorprodukt zum Einschieben des ersten Vorprodukts bereitgestellt und mit der Falzinnenseite dem ersten Vorprodukt zugewandt ist;
• Fördern des ersten Vorprodukts in das bereitgestellte zweite Vorprodukt und gegen die Falzinnenseite zur Ausbildung der Kollektion;
• das zweite Vorprodukt übernimmt die Förderrichtung des ersten Vorprodukts;
• Bereitstellen der Kollektion zur Weiterverarbeitung.

An embodiment of a method for producing a collection of precursors by inserting a first precursor into a second precursor according to the invention is characterized by the following steps:

• Providing a first precursor;
• Providing a second precursor having a turn-up fold with a fold inside;
• Conveying the second precursor into an insertion position in which the second precursor is provided for insertion of the first precursor and faces the first precursor with the folded inner side;
• Conveying the first precursor into the provided second precursor and against the inside of the rebate to form the collection;
• the second precursor takes over the conveying direction of the first precursor;
• Providing the collection for further processing.

The further processing of the collection can be, for example, further conveying the collection and / or stacking several collections and / or addressing the collections.

According to one embodiment of the inventive method, the second precursors are not closed after the formation of Umschlag fold until the formation of the collection. In this way, it is possible to dispense with an opening process which may be difficult to carry out in certain types of second precursors.

According to one embodiment of the method according to the invention, the first and / or second precursors may comprise a plurality of printed products. Such printed products may e.g. Advertising leaflets, brochures, magazines, flyers or printed sheets.

The individual printed products can be different printed products, which have different dimensions and / or weights from each other.

The first and second precursors may also include other products, such as samples.

In one embodiment of the method, the first precursor is conveyed in a conveying plane and the second precursor is provided in the conveying plane. This makes it possible to collect a plurality of printed products which differ greatly in their dimensions.

Good results can be achieved if the second precursor is conveyed in the conveying plane of the first precursor substantially perpendicular to the conveying direction of the first precursor in the insertion position. As a result, if necessary, the first and second precursors can be brought together in a simple manner without having to interrupt the production of the first intermediate products.

In a further embodiment of the method, the second precursor may have a primary fold (or fold edge). Such a primary fold (or folded edge) can be, for example, a fold and / or a stitching and / or a binding of a printed product.

Particularly short cycle times in the execution of the method can be achieved if a second precursor has a primary fold and is conveyed ahead during conveying into the insertion position with the primary fold.

In a further embodiment of the method, the second precursor comprises a plurality of printed products which each have a primary fold, wherein the printed products are oriented so that their primary fold is provisionally arranged during conveyance into the insertion position.

A further embodiment is characterized in that the second precursor is not half-folded, but so that the Umschlag fold divides the second precursor into a larger and a smaller partial area. If a collection produced in this way is laid flat with the larger upper surface lying on the upper side, then the weight of this larger partial surface prevents a re-opening of the second intermediate product handled around the first intermediate product. As a result, in certain cases (if desired) can be dispensed with further fasteners (such as glue spots).

In one embodiment of the method, the second precursor can be provided with the Umschlag fold during conveying into the insertion position. Such an embodiment has u.a. the advantage that (if desired) the same means for conveying as for folding can be used, whereby a device used to carry out the method can be constructed from fewer components. If required, however, the second precursor can also be folded or prefolded in an upstream step.

Alternatively or in addition, the second precursor can already be provided with the Umschlag fold before being conveyed into the insertion position.

The second precursor may also be a closed folded preform that is opened prior to forming the collection.

In one embodiment of the method, the movement of the collection takes place transversely to the orientation of the edge of the Umschlag fold of the second precursor.

According to a further embodiment of the method, a plurality of second precursors are conveyed at least in sections in a shingled arrangement prior to feeding, in which a leading second precursor is arranged in each case above the second precursor following it. In this way, the conveying speed of the second precursors can be reduced and certain second precursors can be conveyed better on curved sections.

In one embodiment of the method, a plurality of second precursors are conveyed in a folded and scaly arrangement in which the after folding outwardly directed outer side of a leading folded second precursor is in each case partially disposed on the inwardly directed after folding inside of the trailing second precursor. As a result, in particular prefolded second precursors can be opened in a simple manner for the combination with the first precursors, since the leading second precursors in each case support the keeping open of the second precursors trailing behind them.

In another embodiment of the method, a plurality of second precursors are conveyed in a scaled arrangement, in which the inside of a leading second precursor is in each case arranged partially on the outside of the trailing second precursor. This can be supported in certain second precursors of the folding and the promotion to the insertion position can be simplified.

For certain applications, according to one embodiment of the method, the second precursor is provided as a section of a paper or film web (hereinafter also referred to as "web").

In one embodiment of the method, the web is a single-ply web, and the second precursor is provided with a turn-up fold having a seam inside before being provided.

In another embodiment of the method, the web is a multilayer web, in particular a folded and / or folded web.

For certain applications, the paper or film web can be unwound from a roll.

In one embodiment of the method, the paper or film web is processed between the roll and the point at which the second precursor is in the insertion position.

In one embodiment of the method, the web is printed on a printing machine and wound on a roll. Subsequently, the web is unwound from the roll again and a second precursor is provided as a portion of the web.

According to another embodiment of the method, the web is printed with a printing press and a second precursor is provided as a section of this web without the web being wound up on a roll therebetween.

In a further embodiment of a method, the second precursor is cut off from the web before it is conveyed into the insertion position. This allows second precursors are promoted at particularly high speeds in the insertion position and thus the cycle times are shortened.

Good results can be achieved if the web wound on the roll is a single-ply web which after being unwound from the roll is folded or folded before a second preproduct is cut off the web.

In a further embodiment of a method, the web is a multilayer folded and / or folded web and the second precursor is at least partially opened after it is cut from the web and before it is conveyed to the insertion position.

Particularly good results can be achieved if the web is cut in a buffer, e.g. a loop buffer - is stored. As a result, on the one hand particularly clean cut edges can be achieved. On the other hand, in this way the cutting process, or the device necessary for it, can be simplified.

According to one embodiment of a method according to the invention, the web is printed with a digital printing press. By using a digital printing machine, if required, a web can be produced with sections of different second precursors. In this way, in a simple way, e.g. Collections made with individualized envelopes.

In one embodiment of such a method, the second precursors can be personalized advertising products whose contents are aimed at a specific recipient or a specific group of recipients. Such a second precursor may alternatively or in addition also include a personal addressing to a recipient or to a recipient group. For example, a recipient group can be formed from the inhabitants of a geographical region, a city, a village or a neighborhood or a building. In a further embodiment of the method, a collection may be completed after completion be promoted more slowly than the first precursor was promoted before the completion of the collection.

In one embodiment, collections are conveyed in a shingled arrangement, whereby the conveying speed of the collections can be reduced. In this case, trailing collection can e.g. each partially over a leading collection are arranged.

A particularly good merging of first and second precursors can be achieved if the promotion of the second precursor takes place in the insertion position against a stop element. Such a stop element may be the promotion of e.g. support and / or limit and thereby influence about the orientation of the second precursor relative to the first precursor, as will be explained in more detail below.

According to one embodiment of the invention, individual print products are provided in an upstream process step N, wherein the first precursor is formed from Nx (x = 1, 2, 3...) Of the N individual print products and the second precursor is formed from the x remaining individual print products becomes. As a result, the costs per manufactured collection can be reduced and additional waste generated by packaging materials can be avoided. The first precursors and second precursors are therefore similar in such an embodiment, so that the second precursors do not represent special or specific packaging means.

In particular, in one embodiment of the method according to the invention, x = 1, ie the first intermediate product can be handled by only a single printed product.

Particularly clean-handled collections can be achieved when a manufactured collection is moved through a piecing device in which the second precursor is pressed against the first precursor.

Good results can be achieved if the first precursor comprises a plurality of printed products having a preferred edge and the printed products are stacked such that their preferred edges together form a stack edge forming an edge region which is conveyed against the inner fold side of the second precursor , When manufactured according to such an embodiment of the method collections, the individual printed products when hand gripping the collection are particularly well secured against slipping out of the collection.

Particularly well handleable collections can also be achieved if at least some of the individual printed products have a fold, a stitching or a binding and are placed on each other so that the folds or stitchings or bonds form a leading edge region which against the Falzinnenseite of second precursor is promoted. In this way, among other things, the risk can be reduced that individual printed products fall by hand gripping the collection of the collection out.

A folded and / or stapled and / or glued edge can also be called folded edge.

In a further embodiment of this method, some of the printed products are to be arranged with their folded edge on the opposite side of the leading edge region in order to achieve a more uniform thickness of the first precursor.

In a further embodiment of the method can be taken as preferred edges of the printed products such edges, which are arranged on the opposite side of the folded edge.

Such an edge can also be called a flower.

If several or all printed products of the first precursor have such a flower, these printed products can be stacked on top of each other with the flowers, so that a leading edge region is formed from the flowers, which is conveyed against the inside of the folded second precursor.

In another embodiment of this method, some of the printed products are to be arranged with their flower on the opposite side of the leading edge region in order to achieve a more uniform thickness of the first precursor.

In a further embodiment of the method, at least some of the printed products have folding edges and are arranged stacked in such a way that the folded edges together form a stacking edge. The stack edge is arranged on the side opposite the leading edge region of the first precursor side, as will be explained in more detail below. Such an embodiment of the method may e.g. be advantageous if the first precursor printed products with divergent dimensions comprises, since thus the thickness of the leading edge region can be reduced, whereby the insertion of the first precursor is favored in the second precursor and a later unwanted reopening of the second precursor is counteracted.

In a further embodiment of the method, at least some of the printed products have flowers and are stacked so that the flowers together form a stacking edge which is arranged on the opposite side of the first precursor to the folded edge side of the second precursor.

A device according to the invention for carrying out such a method generally comprises a first conveying device which conveys the first intermediate product into the opened second intermediate product located in the insertion position and against the inner side of the folded article. Likewise, it comprises a second conveying device, which conveys the second precursor into the insertion position.

In one embodiment of the device according to the invention, the first conveying device conveys a formed collection in the conveying direction of the first pre-product.

In a further embodiment of the device according to the invention, the first and the second conveying device have different conveying directions, which span a common conveying plane. With such a device, in particular first and / or second precursors of stacked printed products can be processed particularly gently.

A particularly reliable and rapid production of collections can be achieved if the first and the second conveying device are arranged so that their conveying directions are substantially perpendicular to each other. This is especially true when the first and second conveyor devices span a common conveyor plane, i. the second conveyor promotes the second precursors from one side into a transfer area into which the first precursors are pushed into the second precursors.

In such an embodiment of a device, the second precursors are conveyed substantially in the direction of the edge of their Umschlag fold in the insertion position. The movement of the collection then takes place across the edge of the envelope fold.

In particular, such movement transverse to the edge of the envelope fold may be perpendicular to the edge of the envelope fold.

In a further embodiment of the device, the first and second conveying device clamp a horizontal common conveying plane.

Particularly clean Umschlagfalze can be achieved when the second conveyor is associated with a pressing unit, which folds the second precursor before reaching the insertion position.

In one embodiment of this aspect of the invention, the press unit comprises at least one press roller pair.

A particularly stable folding operation and at the same time an advantageous conveying in the insertion position can be achieved if the device has a press unit with two or more pairs of press rollers.

In a further embodiment of the invention, a press roller pair comprise at least one Segmenfirolle, as will be explained in more detail below.

If necessary, a second precursor may be grooved prior to the production of the envelope fold.

If necessary, a second intermediate product can also have a plurality of turnover folds. This can be advantageous in particular for relatively thick first precursors, since in this way a refolding of the second precursors can be efficiently counteracted.

In one embodiment of the device, the device comprises a device which ensures the feedability of the supplied second precursor. Such a device may supply the supplied second precursor before and / or during conveyance into the insertion position, e.g. lead and / or open and / or align relative to the first precursor and / or hold, as will be explained in more detail below. Such a device may, for example, have ironing or plate-shaped elements, which reshape the second precursor so that it is opened. To support this opening process of the second precursor also compressed air can be used.

Particularly clean handled collections can be achieved when the device has a piecing device in which the second precursor is pressed against the first precursor. If necessary, such a piecing device can also effect a targeted compression of the collections to be produced.

Good results can be achieved if the piecing device has at least one press roller pair or press roller pair through which the collection is guided.

In order to precisely align the first and second precursor relative to each other, the device may have a stop member which limits the promotion of the second precursor in the insertion position. Such a stop element may comprise, for example, a stop bar or a stop slide.

Good results can be achieved if the stop element comprises at least one combination roller. Alternatively or in addition to the mentioned orientation of the second precursor, such a combination roller can if necessary promote the first and / or second precursor in the region of their combination and / or initiate and / or support the closing process of the second precursor after the introduction of the first precursor, as described below will be explained in more detail. In particular, such a combination roller can support if necessary a clamping promotion of the precursor. Particularly good results can be achieved if the combination roller is a tapered roller or truncated cone roller, or a roller with hemispherical profile, or role with a bell-shaped profile.

Good results can be achieved if a combination roller and a second conveyor are arranged to each other, that a second intermediate product is promoted by the second conveyor until it is clamped between the combination roller and the first conveyor, and thereby a further promotion in the conveying direction of second conveyor is prevented.

According to one embodiment, the first and / or second conveyor device comprises belt conveyors. Such embodiments of the invention allow easy and safe transportation of many types of precursors and collections.

In one embodiment of a device according to the invention, the first conveying device comprises at least two transport paths lying in one plane, between which an at least temporary conveying gap is left free, in which the second precursor is brought into the insertion position. In this way, the second precursor can be particularly easily brought into the insertion position. Such an at least temporary conveying gap may be, for example, a gap in a belt conveyor.

In order to be able to process particularly heavy and / or soft first precursors, the device can have a conveyor table which conveys the first precursor into the second intermediate product located in the insertion position.

Alternatively or in addition, the first precursor can also be partially and temporarily raised from the conveying plane during insertion into the second precursor.

In a further embodiment of a device according to the invention, at least a portion of the second conveying device can be moved in the conveying direction of the first precursors. In this way, when the first precursor is conveyed into the opened second precursor, the relative velocity between the first and second precursor may be set differently from the conveying speed of the first precursor. As a result, if necessary, a particularly gentle merging of the first precursors can be achieved, or it can be made particularly compact collections.

In order to prevent a reopening of the transferred second precursors, a device according to the invention can have a gluing device, which glues the first and / or the second precursor so that they adhere to one another at least temporarily. Good results can be achieved, for example, by using removable adhesives, for example as glue spots and / or glue beads.

According to one embodiment of a device according to the invention, means for providing a paper and / or film web (web) are assigned to the second conveying device.

A particularly space-saving device can be achieved if it comprises means for feeding a second precursor wound up as a section of a web on a roll.

According to a further embodiment of a device according to the invention, the second conveying device is assigned a cutting device for cutting off the second intermediate product from the paper or film web. This cutting device can be arranged in the conveying path of the second conveying device and be set up so that it cuts off the second precursor from the paper or a film web. In this way, the second precursor of the device can be supplied as a web. Thereby, as already described, in a simple manner, if necessary, e.g. individualized collections are produced.

According to a further embodiment of a device according to the invention, the latter comprises a cutting device which separates the second precursor from a paper or a film web (web) cuts off. In this way, the second precursor of the device can be supplied as a web. As a result, individualized collections can be produced in a simple manner, if required, as already described.

Good results can be achieved if the cutting device has a laser and / or a static and / or a rotating and / or a movable in the conveying direction of the second precursor knife.

In a further embodiment of a device according to the invention, this device comprises means for opening or holding open and guiding a folded or folded second precursor after it has been cut from a web by a cutting device.

A particularly space-saving device can be achieved if it comprises means for feeding a second precursor wound up as a section of a web on a roll.

WAYS FOR CARRYING OUT THE INVENTION

The Figures 1 and 2 schematically show a first embodiment of an operating device according to the invention. The device has a horizontal first conveying device 11 with a conveying plane 17. The first conveying device 11 comprises a first transport path 12, are conveyed on the first precursors 1. The illustrated first precursors 1 are printed products 7, 7 ', 7 "The first transport path 12 comprises belt conveyors spaced apart from one another, the first precursors 1 being transported between the belts of the belt conveyors, in order to transport first precursors 1 of different dimensions 2, the upper one of the two belt conveyors is resiliently supported in the vertical direction, and the second transporting route 13 is also substantially constituted by a belt conveyor Fig. 2 can be seen, the apparatus shown also includes a second conveyor 14, with which second precursors 3 of the first conveyor 11 are conveyed laterally. In the in the Figures 1 and 2 the embodiment shown, the second precursors 3 of the second conveyor 14 at least partially promoted in a shingled arrangement. The second conveyor 14 can also do a folding unit, as for example in the EP 2462043 B2 will be described. In the region of the second conveying device 14, a pressing unit 26 is arranged, which comprises two pressing roller pairs 27, 28. With these press roller pairs 27, 28, the second precursors 3 are conveyed on the one hand to the first conveying device 11 (shown schematically with the arrow), and on the other hand also folded, so that an envelope fold 4 is formed. For this purpose, the cylindrical press roller pairs 27, 28 compress the prefolded (or previously grooved) parts of the second precursor 3 in the region of the prefold and emboss or fix, thus the Umschlagfalz 4. Here, the closer to the first conveyor 11 arranged press roller pair rotates 28 faster than the other pair of press rollers 27, whereby the second intermediate product 3 to be conveyed into the insertion position is accelerated relative to the subsequent second precursors 3, whereby the scaly arrangement is resolved and only a single second precursor 3 is conveyed into the insertion position. During the folding process, the second precursors 3 are partly guided by a device 25 in order subsequently to enable the insertion of the first precursors 1. The device 25, also shown only schematically, consists of two bow-shaped guides, which in the Figures 1 and 2 Lift part of the second precursor 3 lying above the turn-over fold 4 in the vertical direction upwards. The first and second conveying devices 11, 14 are synchronized with one another, so that the second conveying device 14 in each case conveys a second intermediate product 3 into the insertion position shortly before a first intermediate product 1 enters a transfer region 24 is promoted, in which the two precursors 1, 3 are brought together. During this merger, the first precursors 1 are conveyed by a first combination roller 22 and partially fixed on the first transport path 12. A second combination roller 23 simultaneously helps to position the second precursor 3 in the conveying direction of the second conveyor 14 relative to the first precursor 1, and also to initiate the second precursor 3 after the merger the closing process. The device also has a support surface 29 in the transfer region 24, which supports the positioning of the second precursor 3, as will be explained in more detail below (cf. Figures 9 and 10 ). The first and second conveying devices 11, 14 are synchronized so that as soon as a second precursor 3 is in the insertion position in the transfer area 24, a first precursor 1 is conveyed into the provided second precursor 3 and against the folded inner side 5, whereby a collection 20 is formed becomes. The formed collections 20 are subsequently conveyed away on a second transport path 13. The collections 20 are guided through a stacking device 8, in which the second precursor 3 is tightly applied from two directions by means of press rolls 9, 10 to the first precursor 1.

The in the Figures 1 and 2 Each of the first preproducts 1 shown consists of different combinations of large, medium and small printed products 7, 7 ', 7 "stacked on top of one another, which each have a fold (or a folded edge) and are stacked in such a way that their folds / fold edges are preceded by a fold Form stack edge 2, which in the merger of the first and second precursors 1, 3 respectively against the Falzinnenseite 5 of the associated second precursor 3 is promoted. The flower of the largest printed product 7 forms a trailing stacking edge 6. Dermassen constructed first precursors 1 allow a safe turning over a second precursor 3 to all to be wrapped printed products 7, 7 ', 7 " Collection 20 individual printed products 7, 7 ', 7 "fall out of the collection. A simple gripping of all precursors by means of a handle is ensured in this type of collections.

The in the FIGS. 3 and 4 schematically illustrated embodiment of an inventive device is substantially the same as that in the Figures 1 and 2 constructed device. However, the printed products 7, 7 ', 7 "are here stacked such that their flowers form a trailing stack edge 6. The first precursors 1 stacked in this way are respectively connected to the folded edge of the printed product 7 which is at the bottom and which is a leading edge of the first precursor 1, is advanced in the provided second precursor 3 and against the inner fold side 5. A method with stacked first precursors 1 constructed in this way may be advantageous for converting first precursors 1 having a relatively large total thickness (or large maximum stack height) Since such first precursors 1 have a reduced thickness (or height) in the region of the leading edge, insertion is simplified, and thus folded second precursors 3 remain better in the turned over state Stack edge 2 on one side and the folded second On the other hand, the pre-product 3 has a precisely defined external shape, which simplifies its further processing.

The in the FIGS. 5 and 6 schematically illustrated embodiment of an inventive device is again similar to that in the FIGS. 1 to 4 constructed devices. The printed products 7, 7 ', 7 "of the first precursors 1 in turn each have a fold (or a folded edge) and are stacked so that their folds / fold edges form a leading stack edge 2. However, the second precursors 3 are not here Such an embodiment of the invention may be advantageous in order to process, for example, particularly large and / or heavy second precursors 3. Likewise, the apparatus shown has one, in comparison to the ones shown in FIGS FIGS. 1 to 4 shown, relatively large support surface 29, which also supports the manufactured collections 20 when they are passed through the stacking device 8. The first precursors 1 are constructed in the same way as in the Figures 1 and 2 represented first precursors 1.

The in the FIGS. 7 and 8 schematically illustrated embodiment of an inventive device is analogous to that in the FIGS. 5 to 6 constructed device. The printed products 7, 7 ', 7 "of the first precursors 1 are again arranged stacked in such a way that their flowers form a trailing stack edge 6. However, here the first precursors 1 are in the in the FIGS. 3 and 4 constructed way.

The Fig. 9 3 shows a perspective view of a further embodiment of a device according to the invention with a press unit 26, comprising first and second press roller pairs 27, 28, which form the formation of an envelope fold 4 at least supported in the second precursor 3. Both the press unit 26 shown, as well as the first and the second press roller pair 27, 28 contained therein can be considered in combination or individually as a separate inventive concept. As such, in particular, both the press unit 26 with the two press roller pairs 27, 28 as shown in combination with each other or the two pairs of press rollers 27, 28 individually taken in each case in other embodiments of the invention devices can be used. The first press roller pair 27 includes upper and lower cylindrical press rollers 31, 32, whereas the second press roller pair 28 has a lower cylindrical press roller 34 and an upper segment roller 33 having a circumferentially varying radius. The segmented roller 33 has an area (conveying segment) with an increased radius, which is configured such that a second precursor 3 arranged between the second pair of pressing rollers 28 can be conveyed in a clamping manner in the direction of the first conveying device 11 or of the transfer area 24. The second press roller pair 28 can be set up so that a second intermediate product 3 passing through it is folded (or embossed) by the press rollers 33, 34, or a fold of the turn-over fold 4, for example, already initiated by the first press roller pair 27, is reinforced. In particular, however, the second press roller pair 28 can also be designed so that it does not substantially change an existing turn-up fold 4, but primarily serves to convey the already folded second feed product 3. By using such a segmented roller 33, it becomes possible to clampingly feed a second precursor 3 until shortly before the merger with the first precursor 1 (or until reaching the insertion position safe to promote), but to release the clamping after generation of the collection 20 safe. Such a second press roller pair 28 can therefore also be arranged in the transfer region 24 between the first and second transport path 12, 13, without the production of the first precursors 1 or of the collections 20 being impaired as a result. The second precursors 3 are also folded so that in the Fig. 9 each lying over the first precursors 1 parts of the folded second precursors 3 are greater than the lying under the first precursors 1 parts. As a result, it is prevented in the illustrated horizontal collections 20 that the second precursors 3 unfold again.

Fig. 10 schematically shows the transfer area 24, in which from a first and second precursor 1, 3 a collection (not shown) is generated. For this purpose, the second precursor 3 is clamped by a press unit 26 so that an envelope fold 4 is formed. At the same time, the second precursor 3 thus folded is conveyed into the illustrated insertion position. In this case, the second precursor 3 is guided in the illustrated area above the Umschlag 4 by the existing of two round profiles device 25 and held in the open state. Below the Umschlag fold 4, the second precursor 3 is guided by a support surface 29. As soon as the second precursor 3 is in this insertion position, the first intermediate product 1 is conveyed by the belt conveyor of the first transport section 11 into the opened second intermediate product 3 and against the inner side 5 of the folded sheet, whereby a collection (not shown) is formed. This is then fed by the belt conveyor of the second transport path 13 of the further processing.

The Fig. 11 shows in a perspective view a further embodiment of a device according to the invention with a pressing unit 26 which is substantially the same as the in Fig. 9 shown pressing unit 26 is constructed. However, the second precursors 3 are provided here as portions of a web 30. This web 30 was printed in a preceding (not shown) printing process, pre-folded and then wound on a roll 41 in the folded state. In the apparatus shown, the web 30 is unwound from the roll 41 and the second precursors 3 are separated from the web 30 by a cutter 42. Subsequently, they are opened by means of the device 25 and guided to the press unit 26, which at least supports the formation of a Umschlagfalzes 4 in the second precursor 3.
