Description
Patented Sept. 5, i933 UNrrED -s'rAres Pirli-:N'rr OFFICE 7 Claims.
This invention relates toa paper press belt and has for an object to provide an improved endless paper 'press belt with self opening and self closing perforations.
In theV manufacturing process of paper the wet paper web as it leaves the wire is freed as much as possible from its water contents by pressing the paper between one or more pairs of press rolls before it reaches the dryers.
By pressing the paper between these press rolls water accumulates on rolls and this water is apt to be drawn in between the rolls, thereby causing the wet paper to be crushed. To avoid this, endless wool felts, so called press fel passing through between the press rolls with the paper web separate the paper'web from the lower press roll. These felts being of-a more or less open weave permit the water that is being pressed out of the web to pass through the felt, the felt/thereby separating the paper web from the water and preventing the crushing of thefpaper` These press felts have to be made from wool of excellent quality to stand the various severe requirements. They are very expensive and they last, as a rule, only a few weeks. Thse felts very fften cause a great deal of-trouble and faulty paper in which case they have to be replaced with new ones. Press felts always cause more or less impressions of the weave in the paper so called felt marks which are objectionable. A felt of the nature just referred to is disclosed in Patent No. 1,844,294 issued Febru,
ary 9th, 1932.
The purpose of this invention is to replace these press felts with an endless belt, perforated in such a manner that the perforations in same open automatically to let oif the water which the press rolls press out. To avoid impressions of these perforations on the surface of the paper, the perforations are made in such a way that they automatically close up when the belt passes the point where the pressure between the press rolls exists, thereby rendering the surface of the belt perfectly smooth.
vBy closing these perforations the endless belt presents a perfectly smooth surface, also imparting such a smoothrsurface to the paper which is not possible with press felts as they always cause in the paper felt marks to a greater or lesser degree. size and the arrangement ofthe perforations can be varied according to the requirements.
The belt moves at the same speed as the paper. The belt can be driven by the press the lower of the two The shape, number,
rolls or by any other device. Guide rolls hold lthe belt in proper position. One or more stretch rolls serve to give. it the desired tension.
The belt may be made from rubber, natural or artificial leather or compositions thereof, guttapercha, balata, metal sheets, cellulose esters, viscose, or from other materials of suicient flexibility, or from compositions-containing the aforesaid materials. VThe belt may be reinforced with a libre web or a metal web or both, or `with threads, or wires, or both, running either crosswise or lengthwise, or both. The belts may also beA made from bres or iibre web coated or impregnated with rubbe guttape'rcha, resins, viscose,'cellulose esters, or other similar flexible materials, or from metal' sheets in conjunction with one or more of the aforesaid materials. v
The belts 'may' be either smooth on one side, or on both sides, or they may carry designs on one side, or both sides. They may have ribs or elevations of another form on that surface that does not come in contact with the paper, to permit the water that has passed through the perforations to ow off more freely. The belt may also have the aforesaid ribs or elevations, respectively, on the side that comes in contact with the paper, if it is intended to impart to the paper certain effects, respectively, designs.
With the foregoing and other objects in view,' as will hereinafter become apparent, this invention comprises the constructions, combinations, and arrangements of parts, hereinafter set forth, disclosed and shown on the accompanying drawing. In this drawing,
Figure 1 is a top plan view of a fragment of the endless paper press belt,.
Figure 2 is a bottom view of a form showing ribs to permit water to flow olf freely,
Figure 3 is a sectional View taken on line 3--3 of Figure 1.
Figures 4', 5, 6, 7, 8 and 9 are diagrammatic views showing different arrangements of the belt when the diameters of the press rolls are changed,
Figure 10 is a fragmentary plan view showing ribs or designs on top surface of belt imparting same effect to paper, (perforations being in closed position), and
Figure 11 isa modication sectional view showing belt reinforced with wire, etc.
There is shown at 10 a fragment of an endless paper press belt made of any suitable ma-y terial such as above mentioned. A plurality of made either plain on both series of perforations 11 are cut through' the belt 10, each perforation v11 being bevelled as at 12, while a flap 13 formed by the act of perforating the belt has-a bevelled edge 14 complimentary tothe bevel 12, it being apparent from Figures 1 and 3 that when the flap 13 is closed into the perforation 11, the bevel 14 and bevel 12 are complimentary to each other, thus forming a perfectly smooth surface on the top of the belt 10. The belt 10 may be formedl with an otherwise smooth surface on the top and bottom thereof, as shown in Figures 1 and 3, or it may be provided for the series of longitudinal ribs 15 as shownin Figure 2 on the bottom thereof, serving to keep the belt 10 slightly above the lower press roll in operation, therebyV permitting the water that has passed through the perforations 11 to flow olf more freely.
The ribs 15 are spaced on the lower side of the belt 10 when so desired, that is, on the inner surface of the belt that comes in contact withthe lower press roll in operation. At 16, on the belt 10, shown in Figure 10, are shown a series of ribs on the upper surface ofthe belt 10, that is, the surface of the belt 10 that supports the paper as it passes through the press roll. The showing of the rib 16`is intended to diagrammatically represent any desired design or effect that it is desired to have cut in the paper, the rib 16 being placed on the upper surface of the roll 10, that is, that surface of the belt 10 which supports the paper, diagrammatically shown at 20. I'he belt 10 may be surfaces as shown in Figures 1 and 3, or with ribs 15 or other designs on the lower surface for assisting in draining the water off, as shown in .Figure 2, or with ribs or other designs 16 on the upper surface, which ribs or other .designs are to be impressed in the paper 20.
Obviously, both ribs 15 on the lower surface and designs 16 on the upper surface may be provided on the same belt. In Figure 11 a cross section of the belt 10 is shown wherein the belt 10 is provided with a metal or fiber reinforcement 17 running therethrough and reinforcing' the same. If desired, this reinforcement material can be placed on the outer surface of the belt. Y
The Width of the opening of the :perforations may be governed b y the diameter-of the press rolls, the upper press roll being shown at U and the lower press roll at L. Figure 4 diagrammatically shows approximate comparison of the.
that it touches the lower roll before it touches the upper roll, the diameter of the lower roll should be decreased, as in Figure 5, to widen the openings., Instead of one lower roll of a smaller diameter two or more lower rolls of smaller diameter may be installed as in Figure 6... To widen the openings of the perforations a roll of smaller diameter may be inserted between the upper and the lower rolls of regular size, asin Figure 7. If the belt is guided in such a way that it touches the upper roll before it touches the lower roll the diameter of the upper roll should be decreased to widen the openings as in Figure 8. Instead of 4one upper roll of smaller size, two or more upper rolls of smaller size may be installed as in Figure 9. Vacuum may be applied through suction rolls or suction boxes to draw oi the water from the belt as indicated in Figures 1 to 6 by (s).
The novel features and the operation of this device will be apparent from the foregoing description. While the device has been shown and the structure described in detail, 'it is obvious that this is not to be considered limited to the exact form disclosed and that changes may be made therein lwithin the scope of what is claimed .without departing from the spirit of the invenperforations, a plurality of flaps depending from Said belt, opening and closing the perforations automatically without exerting special pressure.
