Definitions

  • the invention relates to a composite fabric as a covering for the sheet-forming part of a paper machine with at least two fabric layers, which are formed by transverse and longitudinal threads and which are bound together by transverse threads.
  • a similar paper machine screen is known from DE-OS-29 17 694, which is, however, open or flat-woven and contains transverse binding weft wires.
  • the invention has for its object to provide a composite fabric of the type mentioned, which has a long runtime even when used on motor and cardboard machines.
  • a composite fabric with these features has a close and firm connection between the two fabric layers, so that the relative movement between the upper fabric layer and the lower fabric layer is severely limited.
  • part of the threads between the points at which it changes from the upper fabric layer to the lower fabric layer runs almost perpendicular to the plane of the composite fabric. This makes the connection between the fabric layers even stronger.
  • the basic idea of the invention is to prevent a relative movement between the upper fabric layer and the lower fabric layer in all three spatial directions as far as possible. Surprisingly, it has been found that this firm binding of the upper fabric layer to the lower fabric layer reduces the overall stress on the threads connecting the fabric layers to one another. This avoids in particular those cases in which a multi-layer paper machine screen becomes unusable in that the threads are destroyed long before the lower fabric layer is ground through.
  • the threads connecting the fabric layers to one another can be binding threads such as those used for. B. from DE-OSen 24 55 184 and 2455185 are known. Binding threads are woven in in addition to the threads forming the fabric layer. So z. B. after every fourth longitudinal thread of the upper fabric layer and also after every fourth transverse thread of the upper fabric layer, a binding thread can be woven, which is also woven into the underlying fabric layer and thereby connects the two fabric layers with each other. In the production of particularly mark-sensitive paper types, however, it is preferable not to weave in such additional binding threads and the fabric layers are bound to one another by their own structural transverse and longitudinal threads.
  • binding threads although they generally consist of very thin plastic wires, are a foreign body in the mesh of the fabric layers, i. H. affect the regularity and uniformity of the tissue image. In particular, they reduce the mesh size at the tying point and thereby reduce the permeability of the sieve at the tying points.
  • Structural threads are used in a specific weave, e.g. B. twill or atlas, understood interwoven transverse and longitudinal threads that form the individual fabric layers.
  • a specific weave e.g. B. twill or atlas
  • the binding threads are still inserted relatively loosely into the fabric mesh and only loop around the threads of the individual fabric layers over short distances, usually only one thread, a structural thread is an inseparable part of a fabric layer and therefore at least in the fabric layer to which it belongs, especially tightly woven.
  • binding threads can generally only wrap around one, two or at most three threads of a layer, since the loops of this tissue layer are present in a layer of fabric for a longer period of time would become too impermeable.
  • the fabric layers are connected by means of their structural threads, this danger does not exist, since the structural threads are not additionally woven in, but are intimately and firmly connected to the rest of the fabric layer. If one of the structural threads of one fabric layer is wrapped around a thread of the next fabric layer, the result is a rigid bond between the two fabric layers. Because both the longitudinal and the transverse structural threads bind the fabric layers to one another, the possibility of a relative movement in the longitudinal direction as well as in the transverse direction is withdrawn from the fabric layers.
  • the structural transverse and longitudinal threads of the fabric layer with the thinner threads are preferably used to bind the fabric layers to one another, that is normally the threads of the upper fabric layer. If the thicker threads of the lower fabric layer were to be incorporated into the finer upper fabric layer, the uniformity of the permeability and the stitch pattern of the upper fabric layer would be disturbed too much.
  • every structural transverse and longitudinal thread of the upper fabric layer is also integrated into the lower fabric layer.
  • a sufficiently firm connection of the two fabric layers can already be achieved in individual cases if, for. B. every fourth or sixth transverse thread and longitudinal thread is looped around a longitudinal or transverse thread of the lower fabric layer after every fourth or sixth longitudinal or transverse thread of the upper fabric layer.
  • the trough-shaped depressions which are formed in the upper fabric layer at the points at which the structural threads are integrated in the lower fabric layer are larger than when the fabric layers are tied together by means of additional binding wires, in particular in comparison to the tying of the fabric layers by means of binding wires made of softer material or particularly fine twine. It therefore depends on the individual case of the permissible marking of the paper web by the troughs, the mechanical load of the screen and the requirements for the uniformity of the permeability of the screen, whether it is cheaper to use the webs by additional binding threads or by their structural transverse and longitudinal threads bind together.
  • the upper fabric layer expediently consists of polyester monofilament.
  • the transverse threads can alternately consist of polyamide and polyester monofilament.
  • the lower fabric layer consists of stronger wires and has a coarser weave. Polyamide has proven particularly useful as a material for the binding threads.
  • the composite fabric can be open or endless woven.
  • FIGS. 1 and 2 show an open woven composite fabric, in which the upper fabric layer 1 consists of warp wires 3 running in the longitudinal direction and weft threads 6 running in the transverse direction and has a plain weave.
  • the lower fabric layer 2 consists of longitudinal warp wires 4 and transverse weft wires 7 and has a four-shaft binding.
  • the number of warp wires and weft wires in the lower fabric layer 2 is only half as high as in the upper fabric layer 1.
  • the wires of the lower fabric layer 2 are considerably stronger than those of the upper fabric layer 1.
  • Both fabric layers 1 and 2 are bound to one another by longitudinal binding wires, the so-called binding chain 5, and by transverse binding wires, the so-called binding weft 8.
  • Binding chain 5 and binding weft 8 form an intermediate fabric and are tied with every fourth weft wire 7 of the lower fabric layer 2 and every eighth weft wire 6 of the upper fabric layer 1 and with every fourth warp wire 4 of the lower fabric layer 2 and every eighth warp wire 3 of the upper fabric layer 1.
  • binding chain 5 and binding weft 8 are interwoven and it is e.g. B. possible that the binding chain 5 always runs over the binding weft 8 or vice versa.
  • connection of the two fabric layers 1, 2 shown in FIGS. 1 and 2 largely prevents a relative movement of the same in the fabric plane.
  • connection of the two fabric layers 1, 2 is achieved by guiding the binding threads shown in FIG. 3, wherein in particular a relative movement of the two fabric layers 1, 2 away from one another, that is to say perpendicular to the fabric plane, is prevented.
  • This is achieved in that the binding threads run as perpendicular as possible to the plane of the fabric between a point at which they are bound in the lower fabric layer 2 and a point at which they are bound in the upper fabric layer 1. In the exemplary embodiment in FIG. 3, this is the binding weft 9.
  • Figures 4 and 5 show a composite fabric of two fabric layers 1 and 2, which with the Fabric layers 1 and 2 of Figures 1 and 2 match. However, the connection between the two fabric layers is different. In the embodiment of FIGS. 4 and 5, this is done by the structural longitudinal threads 3 and transverse threads 6 of the upper fabric layer 1. As FIG. 4 shows, the longitudinal warp threads 3 are at relatively large distances from one another, where they normally lie under the transverse ones Weft threads 6 would lie even further down and around the transverse weft threads 7 of the lower fabric layer 2. The longitudinal thread 3 wraps around the transverse thread 7 of the lower fabric layer 2 at a point at which a longitudinal thread 4 of the lower fabric layer 2 runs under this transverse thread 7 so that the longitudinal thread 3 is protected as far as possible from abrasion.
  • Fig. 5 shows a section in the transverse direction, and one can see the incorporation of a transverse thread 6 of the upper fabric layer 1 in two places in the lower fabric layer 2.
  • the binding points are again chosen so that the transverse thread 6 normally under a longitudinal thread 3 of the upper Fabric layer 1 would run and the longitudinal thread 4 of the lower fabric layer 2 wrapped by the transverse thread 6 runs over a longitudinal thread 7 of the lower fabric layer.
  • the invention is not limited to the types of binding shown in the drawing, i. H. the upper fabric layer 1 and the lower fabric layer 2 can have any type of binding.
  • the fabric layers can consist of monofilament or multifilament, as can the binding threads.
  • the composite fabric consists of two layers of fabric.
  • the top layer 1 is made in plain weave. It consists of 20 longitudinal threads / cm and 22 transverse threads / cm.
  • a shrinkable polyester monofilament type was chosen for the warp or longitudinal threads 3, namely the type Trevira 940 with a relatively high modulus of elasticity.
  • the diameter is 0.22 mm.
  • the weft or cross threads 6 are also made of polyester monofilament, but a low-shrink type with a low modulus of elasticity (Trevira 900). The diameter is also 0.22 mm.
  • the lower fabric layer 2 is a four-strand fabric, executed in the four-twill cross-twill weave.
  • the fabric has been woven as a weft runner, i.e. that is, the long floats of the weft wires form the running side of the sieve, while the long floats of the warp wires run inside the sieve and are therefore spared from abrasion.
  • the lower fabric layer 2 has 10 warp or longitudinal threads 4 and 11 weft or transverse threads 7 per centimeter / width.
  • the longitudinal threads 4 are made of stretch-stable, strongly shrinking polyester monofilament, type Trevira 940, and have a diameter of 0.35 mm.
  • the transverse threads 7 consist alternately in a 1: 1 rhythm of polyester monofilament, type 900-0 0.40 mm, and the polyamide monofilament, type 6.6-0 0.42 mm.
  • connection of the two fabric layers 1 and 2 takes place through the binding warp wires 5 and the binding weft wires 8 and 9, respectively.
  • Both thread systems are made of polyamide monofilament, type 6.6, and have a diameter of 0.20 mm.
  • the binding warp wires 5 are provided after every second warp wire 4 of the lower layer 2, and the binding weft wires 8 and 9 are provided after every second transverse wire 7 of the lower layer 2.
  • binding warp wires 5 While all binding warp wires 5 have the same course and are bound in as shown in FIG. 1, the course of the binding weft wires is different: alternately, the binding weft wire 8 is guided flat between the fabric layers 1 and 2, as shown in FIG. 2 and from one layer led almost vertically down to the other, as shown in Fig. 3.
  • the finished and sewn fabric is then given a dirt-repellent coating, which means that the stitches remain open and free of dirt particles from the paper pulp and are permeable even after a long period of use.
