Definitions

  • the invention relates to a double-layer sieve for the sheet-forming part of a paper machine, which consists of weft threads arranged in pairs one above the other and running transversely to the machine direction and warp threads running in the machine direction, all the warp threads being integrated in the upper layer of the sieve and the weft threads and warp threads being made of plastic monofilament .
  • Such screens are known from DE-OS Nos. 2263476 and 2540490. With these screens, all warp wires bind under the weft wires on the running side and are therefore exposed to abrasion. Since double-layer sieves tear open immediately when grinding through the warp wires - the warp wires transmit the entire driving force that acts on the sieve - the wear of the warp wires is the usual cause of the failure of a sieve. This is especially true for the sieves according to DE-OS No. 2263476, in which the warp wires are looped through long before the weft wires on the running side are used up. According to DE-OS No.
  • this difficulty is partially solved in that the warp wires run only under one weft wire on the running side.
  • the warp bows on the barrel side become significantly shorter, the weft bows become longer and, as a result, the warping of the weft wires can be increased to such an extent that the warp wires on the barrel side are, as it were, embedded within the weft wires.
  • Sufficiently strong fixing means that the weft wires can be looped through in front of the warp wires.
  • weft wires may only be a few hundredths of a millimeter thicker than the warp wires, since otherwise the warp wires are pressed downwards by the stronger and stiffer weft wires and are therefore more exposed to abrasion. It is therefore not possible with such a sieve to use thicker weft wires to increase the abrasion volume.
  • a paper machine screen is constructed from two self-contained fabric webs which are connected by a special binding chain.
  • the binding chain runs partially on the barrel side under the weft wires and is therefore exposed to grinding. The thinner the binding chain, the more it is looped through.
  • Such a sieve made up of two self-contained fabric webs is very expensive and complex.
  • the invention has for its object to provide a double-layer, intended for the sheet forming part of a paper machine, which has a longer running time with low screen marking in the paper and high stability in the transverse and longitudinal directions.
  • the running time is additionally extended by the larger abrasion volume of the lower weft threads.
  • the embodiment of the invention specified in claim 4 doubles the cranking effect of the warp threads, i.e. the weft thread is bent more and the warp threads are better protected against abrasion.
  • the sieve according to the invention is easiest to manufacture if the number of warps on the paper side is twice as high as on the running side, since then every second warp wire is not woven into the lower layer. However, it is also possible to weave only every third, fourth, etc. warp wire into the lower layer, so that the ratio of the warp numbers in the upper or lower layer is 3: 1.4: 1 1, etc.
  • the warp number of the upper layer used to form the paper web is preferably at least twice as high as that of the lower layer.
  • the screen according to the invention has all the advantages of a double-layer screen.
  • weaving requires a smaller number of pinch rollers after weaving one Siebes happens the switch to any conventional bindings without any move in the harness system.
  • the sewing of the flat-woven sieves is also done with conventional equipment and is significantly easier than with sieves made up of several individual fabric layers, in which each individual fabric layer has to be sewn separately.
  • the length of the weft floatation on the barrel side can be shortened if necessary without changing the screen structure of the paper side by looping the warp wires that are integrated in the lower layer not just once per repeat, but twice or more times, or under two Shots of the lower layer are performed.
  • the free weft float can be shortened from 9 to 7 warp wires without the advantages of this new type of fabric according to the invention being nullified or impaired, because at least half of the warp wires remain hidden inside the screen until the end of the runtime in full strength, since they do Are not exposed to abrasion.
  • the warp wires and the weft wires are formed by a plastic monofilament; polyester and polyamide monofilaments are particularly suitable. Because of the difficulty of round weaving double-layered sieves, the sieves are woven flat.
  • Another advantage of the screen according to the invention is that, because of the higher number of warps in the upper layer, the paper side of the screen has a finer structure and leaves a weaker mark in the paper.
  • the power transmission chain can be thinner than the construction chain or can be made of less stretchable material than the construction chain. In particular, more elastic material can be used for the construction chain than is usually used for warp wires in a paper machine wire.
  • the screen shown in FIGS. 1 to 3 is woven flat, that is, the warp threads run in the machine direction and the weft threads crosswise to the machine direction.
  • the sieve contains two layers of weft wires, namely the upper weft wires 3, which form the paper side of the sieve, and the lower weft wires 4, which form the running side of the sieve.
  • An upper weft wire 3 is arranged above a lower weft wire 4, i.e. the weft wires are available in pairs.
  • the screen contains at least two types of warp wires, namely a so-called construction chain 1, which is integrated in the upper layer 5 and the lower layer 6, and a so-called power transmission chain 2, which is only integrated in the upper layer 5.
  • the sieve according to the invention can have any type of weave, ie twill weave, satin weave or a derived weave.
  • the screen preferably has satin weave, ie the weave points do not touch each other and are evenly distributed.
  • the number of warps on the paper side of the wire is significantly higher than on the running side, since part of the warp wires, namely the power transmission chain 2, is not integrated in the lower layer.
  • the power transmission chain 2 is therefore not ground during operation and does not suffer any abrasion.
  • This power transmission chain 2 can still use the fabric tension Pick up when the warp and weft wires on the running side (lower layer 6) of the sieve have already been completely ground off.
  • the power transmission chain 2 should also run as far as possible inside the screen in order to obtain a screen that is as free of markings as possible and to achieve a good web acceptance.
  • the power transmission chain 2 should have as few bends as possible, ie have a straight course, in order to give the screen a high degree of longitudinal stability and a small constructional stretch.
  • FIG. 4 and 5 show the fabric image of the paper side or the running side of a screen according to the invention.
  • the top view of FIG. 4 shows a 5-shaft atlas and that of FIG. 5 shows a 10-shaft atlas.
  • the binding points 7 correspond to the cranks of the construction chain 1 and the power transmission chain 2, while in FIG. 5 the binding points 8 only originate from the construction chain 1.
  • FIG. 6 shows a variant of the embodiment according to the invention.
  • the construction chain 1 runs on the running side under two weft wires (FIG. 6).
  • the force transmission chain 2 runs predominantly inside the sieve and only binds the weft wires 3 of the upper layer 5.
  • the necessary tensile strength of the fabric is retained after the lower layer of the sieve has been destroyed.
  • the course of the power transmission chain 2 is the same for both bindings, so Figures 2 and 7 are identical.
  • FIGS. 4 and 9 The structure of the top layer of both screen designs is also the same, therefore the fabric image in FIGS. 4 and 9 is identical. Only the lower layer of the screen (FIG. 10) shows an extension of the warp crooks 8 and a shortening of the crooks 9 of the weft wires. In the cranking 8 on the running side, the two warp wires 1 are always in pairs, which doubles the cranking effect of these warp wires.
  • a weave with at least 10 shafts and an atlas distribution was shown. Controlling the length of the weft floats in the lower layer is particularly important for fabrics with a higher weave repeat, so that the length of the weft bend on the barrel side can be adapted to the requirements of the particular case.
  • the lower fabric layer 6 is woven with substantially thicker weft wires, namely with a diameter of 0.27 mm polyester monofilament, with the possibility of alternately weaving polyester and polyamide monofilaments into this layer to further increase the abrasion resistance.
  • the alternation can be 1: 1, in extreme cases 2: 1, in which case two polyamide wires and one polyester wire are woven.
