Definitions

  • the present invention relates to a papermaking fabric according to the preamble of claim 1.
  • Such a paper machine screen can be used / used, for example, in the wet end of a paper machine for dewatering / filtration of the paper pulp and thus for forming the paper sheet (so-called sheet forming screen or formation screen).
  • such a papermaking screen may be formed as a so-called long-floating screen, i. as a screen whose lower transverse threads on the running side have long floats / form.
  • Such screens are mainly used for papers with higher basis weights. These screens are typically used on both fourdrinier and hybrid former or GAP former at all speeds. Such screens are appreciated by papermakers for their long run time.
  • two different materials can be used on the running side to form the lower transverse threads, for example polyester and polyamide.
  • these two materials can be introduced alternately one behind the other on the feed side in the longitudinal direction, with polyester serving primarily to mechanically stabilize the fabric, while polyamide is used primarily to increase the abrasion resistance and thus to extend the running time. Both materials have fundamentally different properties, which also show in the respective behavior of the threads in the tissue.
  • the lower transverse threads are evenly integrated and made of different materials, the sieve after its production (eg after weaving and a subsequent heat setting) to grind flat on the running side, to reduce / exclude a different / uneven protrusion of the lower transverse threads downwards.
  • US 6,244,306 B1 shows a uniform double integration of the lower transverse threads, which leads to a long cross-thread floating on the running side (a transverse thread floating or "cross-thread bridge" over seven consecutive lower longitudinal threads away).
  • the two binding points are each separated by (exactly) a lower longitudinal thread, which overflows the respective lower transverse thread (in the plan view of the lower fabric layer).
  • US 2012/0145348 A1 also shows a uniform double involvement of the lower transverse threads, which leads to a long transverse thread floating on the running side (a transverse thread floating over ten consecutive lower longitudinal threads away), wherein the two binding points of the respective transverse thread are here immediately adjacent to each other, ie by no longitudinal thread are separated from each other, which overflows the respective lower transverse thread (in the plan view of the lower fabric layer).
  • One aspect of various embodiments can be clearly seen in providing a papermaking fabric whose running side is / can be designed to have a high running time and / or a suitable running behavior.
  • An additional or alternative aspect of various embodiments can be seen illustratively in providing a papermaking fabric whose running side is / can be configured to provide high paper quality, especially over a long period of time.
  • An additional or alternative aspect of various embodiments can be seen illustratively in providing a papermaker's fabric having a running side thereof is / may be that it has a high mechanical stability and / or high abrasion resistance.
  • An additional or alternative aspect of various embodiments can be seen illustratively in providing a papermaking fabric whose running side is / can be made uniform, e.g. with a substantially uniform supernatant of the lower transverse threads.
  • the invention provides a papermaker's fabric according to claim 1. Further embodiments / embodiments of the invention are described in the dependent claims.
  • the lower transverse threads are not integrated uniformly but unevenly in the lower fabric layer.
  • the uneven incorporation of the lower transverse threads can compensate for a different behavior of the threads in the fabric (eg because different materials have been used for the threads and / or the threads have different heat-setting properties), for example, such that the lower fabric is specifically designed for Outer side / running side appears substantially geometrically uniform, esp. With a substantially uniform projection of the lower transverse threads (without the requirement of grinding the running side).
  • the thicker diameter e.g. can be selected according to a higher requirement in terms of stability or life expectancy.
  • the seam strength may be increased by a changed course of the lower longitudinal thread within the lower fabric.
  • a papermaker's fabric may be a multi-ply fabric having an upper fabric layer and a lower fabric layer be educated.
  • the multi-layer fabric may consist of upper and lower fabric layers.
  • the upper and lower fabric layers are connected to each other by means of binding threads (eg binding transverse threads).
  • the so-called paper side is formed, for example, from the upper side / outer side of the upper fabric layer, whereas the so-called running side is formed by the underside / outer side of the lower fabric layer.
  • a multi-layered design makes it possible according to various embodiments, a different configuration of the paper side and the running side, so that both sides are adapted to the respective intended use / can be.
  • the longitudinal threads which realize according to various embodiments, the rotation of the screen, be protected by significantly projecting or protruding transverse threads from wear.
  • On the paper side for example, by providing a balanced ratio of longitudinal and transverse threads, a good storage option for the paper fibers can be ensured.
  • the plain weave has proven itself for the upper fabric and thus for the paper side.
  • the plain weave is for the formation of a paper sheet and thus for the paper side, so little is it usually suitable for the running side. If a paper machine screen is provided with a canvas paper side, it may therefore be advisable to provide a second fabric layer below the plain weave which forms the running side of the screen, which gives the screen sufficient stability and wear potential.
  • the upper fabric layer and its connection to the lower fabric layer are not limited to a particular embodiment and can be selected as needed / application. Possible embodiments, which are in no way limiting, are given below.
  • At least the lower transverse threads are thus formed as such threads, which remain exclusively in a fabric layer (namely the lower) / run.
  • the longitudinal threads running in the lower fabric layer can in principle be used as alternating threads (for example in the form of so-called functional longitudinal thread pairs) and / or as threads remaining / remaining in a fabric layer, ie. as lower longitudinal threads, be formed.

That is, in the lower binding repeat, each lower transverse thread is doubly bound.
  • the lower transverse threads are differently incorporated into the lower fabric layer, forming first lower transverse threads and second lower transverse threads, wherein a shortest distance in the transverse direction between the first and second binding sites is greater in the first lower transverse threads than in the second lower Cross threads, so that the first lower transverse threads on the running side form a shorter floating than the second lower transverse threads.
  • the shortest distance in the transverse direction between first and second binding sites may be substantially the same for each first lower transverse thread, and the shortest distance in the transverse direction for each second lower transverse thread may also be substantially equal.
  • the sieve can be designed, for example, as a long-floating sieve, whose lower transverse threads all have long floats on the running side. That is, each lower transverse thread then forms on the running side within the lower Binding repeat a long cross-thread floatation or cross-thread bridge, which extends over more than half of the longitudinal threads away, with which the respective lower transverse thread is woven or which crosses the respective transverse thread in the lower fabric within the lower binding repeat and under ,
  • the running-side floatation of the respective lower transverse thread in the lower weave repeat can also be referred to as the longest or longer distance in the transverse direction between the first and second tie-in points. It is counted / measured in the transverse direction over the edge of the lower binding repeat, since further lower binding repeats can follow (directly) to the left and to the right of the lower binding repeat. For example, for each lower transverse thread the shortest distance is smaller than the longer distance, so that the lower transverse threads all / have long floats on the running side.
  • the greater shortest distance in the transverse direction in the first lower transverse threads can be achieved, for example, in the case of the first lower transverse threads between the first and second binding points, at least one longitudinal thread extending in the lower fabric layer, which overflows the lower transverse thread ( esp. In plan view of the top / inner side of the lower fabric layer, ie in plan view of the side facing away from the running side of the lower fabric layer), is arranged more than in the second lower transverse threads.
