Definitions

  • the invention relates to a spiral link belt with a plurality of intermeshing plastic wire coils in accordance with the preamble of claim 1.
  • spiral link belts are known (DE-A-2419751 and 29 38 221 and EP-A-0018200) and are used, among other things, as clothing in the dryer section of paper machines. Before reaching the dryer section, the sheet formation process of the paper web is largely completed and the paper web is compacted in such a way that it is no longer very susceptible to marking. Due to the risk of marking, it was previously not possible to use the spiral link belts in the sheet forming part of a paper machine.
  • the object of the invention is therefore to provide a spiral link belt which is also suitable for use in the sheet-forming part of a paper machine.
  • the invention further relates to a method for producing the spiral link belt according to the invention.
  • connection loops are preferably woven into the fabric at certain intervals on the underside. These connecting loops can be formed both from the structural weave wires of the fabric and by a wire that is not involved in the design of the fabric structure. This wire can run in the warp or weft direction.
  • the correct shape and size of the connecting loops can be achieved by weaving in auxiliary wires of a certain thickness. If the connecting loops are made from warp wires (from a structural chain or additional binding chain), additional auxiliary weft wires are pulled through at a certain rhythm. These auxiliary weft wires are only wrapped around the warp wires intended for the production of the connecting loops and thus remain on one side of the screen outside of the fabric structure.
  • auxiliary wires now run at certain intervals in the warp direction and are operated by their own, separate stranded wire frames. They are held outside the fabric and only integrated at the junction by the structural or additional binding weft wire.
  • the auxiliary wires are pulled out, dissolved or otherwise removed.
  • the connecting loops of the fabric are inserted between the spiral turns and both layers, i.e. H. the spiral link band and the tissue are connected to each other by inserting plug wires.
  • the thermal shrinkage of these wires should preferably be higher than that of the warp and weft wires of the fabric and the spiral link belt. During the final heat setting, the plug wires are held tight by the high shrinkage of the connecting loops.
  • the material of the plug wires can differ from the material of the fabric and that of the spirals or spirals of the link belt.
  • the plug wires are made of a material with a significantly lower melting temperature than the material of the fabric or that of the coils, e.g. B. polyamide or polypropylene.
  • the inserted plug wires are cut so that they protrude a few centimeters at the edges. After finishing the sieve, the protruding ends of the plug wires are fused using heat or ultrasound. This creates a good leading edge on both edges of the spiral link belt. Embrittlement or the tissue does not become brittle because of their higher melting temperature.
  • the filler material can optionally also be low have lower melting temperature and are fused at the laterally protruding ends to form leading edges.
  • edges of the finished spiral-link belt which is covered with a fabric, can be impregnated with adhesives in a known manner as required, in order to prevent the individual longitudinal threads from coming off the edge after prolonged use.
  • the spiral link belt and the fabric can. also by gluing or ultrasound welding in places or areas. It is also possible to connect a fabric to the spiral link belt by means of connecting eyes as well as by gluing or welding.
  • the fabric covering the spiral link belt can be made endless in a conventional manner, e.g. B. by a woven seam.
  • the fabric is preferably made endless in front of the spiral link belt by a woven seam, or the spiral link belt is opened to make the fabric endless by pulling out a plug wire in order to facilitate the production of the woven seam.
  • the spirals are connected again by inserting the plug wire. Since the spirals connected by plug-in wires absorb the tensile forces when using the fabric-covered spiral link belt, the woven seam can be made very narrow.
  • the advantages of the fabric-covered spiral link belt according to the invention are, in particular, that a very fine structure can be selected for the fabric and thus the desired freedom of marking, the good retention of the paper fibers and the required permeability can be achieved.
  • the spirals can consist of relatively coarse plastic wires.
  • the fabric-covered spiral link belt according to the invention can be used both in the sheet-forming part of the paper machine, that is to say as a paper machine screen, and as a drying screen for particularly sensitive paper types. It can also be used as a conveyor belt or filter medium whenever a stable belt with good drainage properties and at the same time a smooth surface and high retention is required.
  • the fabric can be woven from monofilament or from multifilament plastic threads. It can also be provided with a fibrous web by needling, which also enables use in dewatering presses or in the first groups of the drying party in the production of the finest papers.
  • the spiral link belt 1 shown in Fig. 1 consists of spirals or spirals 2, which are connected to one another by plug wires 3.
  • the spirals 2 intermesh. and the turns of adjacent spirals 2 penetrate each other so far that they form a channel through which the plug wires 3 can be inserted.
  • the spiral link belts are preferably of the type described in DE-A-29 38 221, i.e. H.
  • the spirals 2 have no tension spring tension in the finished spiral link belt, the wire of the spirals 2 is torsion-free and the spiral link belt is heat-set after the spirals 2 have been joined together and the push-in wires 3 inserted so far under tension that the windings of the spirals 2 are somewhat into the material of the Penetrate wires 3 and thereby deform them somewhat wavy.
  • the head arcs of the turns of the spirals 2 are preferably widened and the slope of the spirals 2 is preferably chosen so that the turns are close to each other, i.e. H. it is about twice the wire gauge.
  • the spirals 2 and the plug wires 3 generally consist of plastic monofilaments.
  • the fabric 4 consists of weft wires 5 and warp wires, which are woven together in a plain weave.
  • everybody z. B. tenth warp wire serves as binding chain 6 and forms a connecting loop 7 after a certain number of weft wires - in the present case eight weft wires 5 - the ratio between normal warp wires and binding chain 6 can be chosen according to the needs of the individual case and in extreme cases everyone can Warp wire can be a binding chain 6.
  • the connecting loops 7 are so long that they penetrate into the interior of the spirals 2 when the fabric 4 is placed on a spiral link belt 1.
  • the fabric 4 can thus be connected to the spiral link belt 1, the connecting wires 8 are pushed through the cavity of the spirals 2 and the connecting loops 7 of the fabric 4 protruding into this cavity.
  • FIG. 2 shows a section similar to that of FIG. 1.
  • the connecting loops 7 are formed in FIG. 2 by a special binding chain 6.
  • the binding chain 6 is guided over the two weft wires 5 immediately before and after a connecting loop and otherwise runs under the weft wires 5 bes 4 can be woven in or can be pulled into the fabric afterwards.
  • the structural warp wires 9 and the weft wires 5 in turn form a plain weave. However, any other binding is also possible.
  • the fabric 4 has a double-layer weave, i.e. H.
  • the weft wires 5 are arranged in two layers, and at least some of the warp wires 9 are interwoven with both layers.
  • the binding chains 6 are interwoven with both layers.
  • a spiral link belt similar to that of FIG. 2 is to be produced.
  • the spiral link belt is made from monofilament polyester wires.
  • the spirals have seven turns per cm and are made of a monofilament polyester wire with a diameter of 0.70 mm.
  • the plug wires made of polyester monofilament are 0.90 mm thick and are spaced 5 mm apart.
  • the spiral link belt has a thickness of 2.50 mm and an air permeability of 970 cfm.
  • the fabric has a plain weave.
  • the warp number is 28 wires / cm.
  • the chain is 0.17 mm thick and is made of polyester monofilament with a thermal shrinkage of 11.5% at 200 ° C.
  • the number of weft wires is also 28 wires / cm.
  • the weft wires are made of polyester monofilament, diameter 0.18 mm, and have a thermal shrinkage of 2.2%.
