Definitions

  • the invention relates to a composite fabric as a covering for the sheet formation area of a paper machine according to the preamble of claim 1.
  • Fabrics for the sheet formation area of a paper machine are often constructed from two or three fabric layers, which are in themselves complete fabrics and are connected to one another by additional binding threads.
  • the bottom fabric layer is made of relatively coarse threads because it absorbs the abrasion.
  • the uppermost fabric layer, which carries the paper fiber fleece, on the other hand, is made up of finer threads in order not to cause any marks in the paper. This structure was expected to have a low marking risk on the one hand and a long service life and stability on the other. In practice, however, this expectation has so far not been met.
  • a paper machine clothing according to the preamble of claim 1 is known from EP-A-44 053. Both fabric layers are here single-ply, and the connection of the fabric layers takes place in that the transverse threads of the lower fabric layer bind at regular intervals with the longitudinal threads of the upper fabric layer, the binding of the longitudinal and transverse threads of the upper fabric layer being unchanged at the binding points. It has been shown that such composite fabrics also cause strong marking in the paper web.
  • the invention has for its object to provide a composite fabric as a covering for the sheet formation area of a paper machine, which has a long runtime with low marking.
  • the tying points generally comprise a distance of a few longitudinal threads, e.g. B. a stretch of three longitudinal threads.
  • each transverse thread is integrated into the adjacent fabric layer in this way. In individual cases, however, it may also be sufficient to weave only every second, third or fourth cross thread into the fabric layer above or below.
  • a fabric layer has several layers of transverse threads, generally only the transverse threads of the outer layers are bound into an adjacent fabric layer.
  • the longitudinal threads and the transverse threads consist of polyester monofilament.
  • the longitudinal threads and in particular the transverse threads of the lowest fabric layer, which forms the running side can also consist of a polyamide monofilament because of its higher abrasion resistance.
  • the longer running time of the composite fabric according to the invention as paper machine clothing should be due to the fact that the large number of binding sites between the individual fabric layers means that they are very firmly connected to one another and thereby, for. B. do not perform any relative movement when deflecting around rollers. There is therefore no risk that the transverse threads connecting the fabric layers are exposed to a particular abrasion or a high tensile load due to a relative movement of the layers.
  • the individual fabric layers are not connected by means of special binding threads, but rather by means of the so-called structural transverse threads, i. H. the transverse threads which are involved in the formation of the weave in the usual way.
  • these structural transverse threads are incorporated into a neighboring fabric layer, in deviation from the weave design.
  • Figure 1 shows a composite fabric in which the upper fabric layer 1 has a single-layer plain weave made of longitudinal threads 3 and transverse threads 6 and the lower fabric layer 2 is double-layered with longitudinal threads 4 and upper transverse threads 7 and lower transverse threads 8.
  • the lower layer 2 has a ten-shaft binding.
  • the lower Cross threads. 8 have long floats on the barrel side, so that this is a so-called weft runner in the case of a flat-woven paper machine screen.
  • the transverse threads 6 of the upper layer 1 and the upper transverse threads 7 of the lower layer 2 are of the same thickness and are made of the same material.
  • the longitudinal threads 3 of the upper layer 1 are preferably thinner and made of a material which is more resistant to stretching than the longitudinal threads 4 of the lower layer 2. This is expedient since the longitudinal threads 3 of the upper fabric layer 1 serve primarily to form the paper side, while the lower layer 2 comparable to a drive belt, takes up the entire drive power of the wire section exerted on the paper machine wire.
  • connection of the two fabric layers 1, 2 takes place in that the transverse thread 6 of the upper fabric layer 1, in deviation from the otherwise adhered plain weave, is not tied with a longitudinal thread 3, but runs under a total of three longitudinal threads 3.
  • the upper transverse thread 7 of the lower fabric layer 2 is tied with the longitudinal thread 3, which is omitted from the transverse thread 6 of the upper fabric layer 1.
  • This exchange is repeated at regular intervals, e.g. B. once within each binding repeat or within every second or third binding repeat.
  • FIG. 2 shows a composite fabric similar to that of FIG. 1, but the course of the transverse threads 6 and 7 has been interchanged over a distance of a total of three longitudinal threads 3 of the upper fabric layer 1.
  • Figure shows an embodiment similar to that of Fig. 2, wherein the cross thread of the upper fabric layer 1 within the distance in which the upper cross thread 7 is integrated into the upper fabric layer 1 is bound in the lower fabric layer 2 by being under two longitudinal threads 4 is passed through.
  • the course of the transverse threads 6 and 7 is also interchanged in the embodiment shown in FIG. 4. While the upper fabric layer 1 again has a plain weave, the lower fabric layer 2 is an eight-sided, double-layer fabric. In the case of a longitudinal thread 3 or 4, the course of the transverse threads 6 and 7 is exactly interchanged, i.e. H. the upper transverse thread 7 of the lower fabric layer 2 is guided over a longitudinal thread 3 of the upper fabric layer 1 instead of under the corresponding longitudinal thread 4 of the lower fabric layer 2 and accordingly the transverse thread 6 of the upper fabric layer 1 is guided under the longitudinal thread 4 omitted by the transverse thread 7 instead of over the corresponding longitudinal thread 3.
  • the transverse threads are the weft threads and the longitudinal threads are the warp threads
  • the cross threads, the warp threads and the longitudinal threads are the weft threads.
  • connection of two or more fabric webs which are complete fabrics in themselves, can also be achieved by partially integrating the longitudinal threads of a fabric layer into an adjacent fabric layer or by exchanging longitudinal threads of two adjacent fabric layers.
  • the disadvantage here is that the longitudinal threads are under tensile stress during heat setting and during use in the paper machine. This makes it difficult to maintain the uniform surface structure on the paper side of the paper machine wire.
  • the transverse threads are a type of filling material that is relatively little affected by the longitudinal tension exerted on the paper machine screen. When heat-setting, they lie transverse to the longitudinal stress exerted and form a homogeneous topographical structure despite the deviation from the original course.
  • the upper fabric layer 1 of a composite fabric consisting of two fabric layers is openly woven with 30 longitudinal threads per centimeter and 34 transverse threads per centimeter in plain weave.
  • the longitudinal threads 3 have a diameter of 0.15 mm and consist of a polyester monofilament of medium to low longitudinal stability and medium modulus of elasticity (Trevira 930).
  • the transverse threads 6 also have a diameter of 0.15 mm and consist of a polyester monofilament with a very low modulus of elasticity and low thermal shrinkage (Trevira 900).
  • the lower fabric layer 2 is an eight-sided, double-layer fabric with long floats of the transverse threads on the running side and shortened floats on the top.
  • the lower fabric layer 2 is open-woven with 15 longitudinal threads per centimeter and 17 transverse threads per centimeter.
  • the longitudinal threads have a diameter of 0.30 mm and are made of polyester monofilament with a high modulus of elasticity.
  • the upper transverse threads 7 of the lower fabric layer 2 are made of the same material and have the same diameter as the transverse threads 6 of the upper fabric layer 1, so that the surface structure of the composite fabric on the paper side is unchanged even at the connecting parts.
  • the lower transverse threads 8 of the lower fabric layer 2 are made of a particularly abrasion-resistant material and alternate made of polyester monofilament and polyamide monofilament with a diameter of 0.32 mm.
  • the upper fabric layer 1 and the lower fabric layer 2 are connected to one another as shown in FIG. 4, each transverse thread 6 of the upper fabric layer 1 and each upper transverse thread 7 of the lower fabric layer 2 being interchanged on every eighth longitudinal thread 3 and every fourth longitudinal thread 4, respectively .
