Definitions

  • the invention relates to a covering for paper machines from a two- or multi-layer fabric.
  • the individual fabric layers are interconnected in that at least some the cross threads are double and only one of the double cross threads at a tying point the longitudinal threads of the other fabric layer is woven.
  • the covering is in particular a those for the sheet formation area of a paper machine.
  • Paper machine clothing in which the fabric layers are not through special binding threads, but through the so-called structural threads are interconnected are known (EP-A-44 053). Form in such paper machine clothing at the tie-down points, these are the places where the thread of one fabric layer is woven into another fabric layer is, depressions or depressions, the corresponding markings left in the paper.
  • EP-A-80 686 is a double-layer Paper machine wire known d. H. a paper machine screen, that from two layers of wefts that exists with a single system of Warp threads are interwoven. A low mark is achieved in that the warp threads so that the fibers of the paper web supported by a surface structure, by having the same design features the warp thread guide is changed so that results in a double chain.
  • lines 17 to 22 is mentioned a double chain for single-layer paper machine screens no advantage. This must also be done analogously for multi-layer paper machine screens that apply also as a combination of several single-layer fabrics can be viewed.
  • the invention specified in claim 1 solves the task of a paper machine clothing of the generic type with regard to the marking properties to improve.
  • the force with which the the two fabric layers are drawn towards each other, can be further reduced by the fact that the double threads cross alternately are integrated into the other fabric layer.
  • a tying point becomes the one cross thread a pair of threads in the other fabric layer woven in while at the next tying point the other thread of the pair is woven.
  • the paper side are preferable not just double those cross threads executed, which are woven into the other fabric layer are, but all transverse threads are double executed. This results in the additional Advantage that significantly more bases for the Fibers of the paper web are present as well improves paper quality.
  • the two single threads of the double Cross threads preferably have the same Cross-section.
  • a double one Cross thread of the paper machine screen according to the invention thus has approximately the same total cross-sectional area like a cross thread of a paper machine screen According to the state of the art.
  • cross-sectional area each single thread of a double thread Cross thread is only 30% smaller than that Cross-sectional area of the longitudinal threads in the upper fabric layer.
  • Cross-sectional area of each individual thread one double executed cross thread of the upper fabric layer approximately between 50 and 70% of the cross-sectional area of a longitudinal thread.
  • the individual fabric layers can be a plain weave, Twill weave or satin weave have or derived bonds.
  • the upper fabric layer, paper side can e.g. Legs Plain weave, while the lower Fabric layer, running side, a four-twill weave with long floats visible on the barrel side who can have cross threads.
  • the lower fabric layer and in the upper fabric layer are in threads running in the same direction are duplicated.
  • the upper fabric layer Cross threads run twice, so the one Cross thread of the pair, also in the lower Fabric layer is integrated at every tying point between the double threads the lower fabric layer and the one on the Tying involved longitudinal thread included and thereby the abrasion almost completely withdrawn.
  • Cross threads 1 and longitudinal threads 2 form together the upper fabric layer 3 of the paper machine clothing or the paper machine screen. They are in a plain weave with each other interwoven. Longitudinal threads 5 and transverse threads 6 form the lower fabric layer 4, which also m woven in plain weave.
  • the cross threads 1 of the upper fabric layer 3 are executed twice. d. H. instead of a cross thread a pair of transverse threads is woven.
  • the two Except for cross threads 1 of a pair the tie point 7 the same course.
  • At the Tie point 7 is a cross thread 1a of the pair in the lower fabric layer 4 incorporated while the other cross thread 1b in the upper fabric layer 3 remains. Separate at tie point 7 So the two transverse threads 1a and 1b one Cross thread pair.
  • the next tying point is preferably the other Cross thread 1b woven into the lower fabric layer 4, the function of the two transverse threads 1a and 1b is therefore interchanged at each tying point 7.
  • the paper machine screen consists of two layers of fabric 3, 4, each for its own Plastic wires are woven open, namely the upper fabric layer 3 from warp wires 2 and Weft wires 1 and the lower fabric layer 4 Warp wires 5 and weft wires 6.
  • the upper fabric layer 3 has a plain weave and has a warp wire density of 29 wires per cm with a warp wire diameter of 0.18 mm.
  • the warp wires are made of Trevira monofilament Type 940.
  • the lower fabric layer also has a plain weave.
  • the number of warps is 14.5 warps per cm with a diameter of 0.27 mm.
  • the Warp threads are made from Trevira Monofil Type 940.
  • the two layers of fabric are connected that a weft wire at regular intervals for a pair of weft wires in the upper fabric layer the warp wire of the lower fabric layer wraps around.
  • This binding takes place in everyone eighth warp wire of the upper fabric layer or every fourth warp wire of the lower fabric layer instead, so that the individual wires of each pair of weft wires over a distance of 7 warp wires the upper fabric layer run together.
  • every eighth pair of weft wires the upper fabric layer on the binding involved.
  • the 7 weft wire pairs in between the upper fabric layer are never with the warp wires of the lower fabric layer tied.
  • Every eighth pair of weft wires is one of the single wires with the warp wire lower fabric layer tied off during the other weft wire of the pair the normal weave continues unaffected, causing the Formation of a depression or depression on it Tie point 7 is avoided.
  • the binding points of the individual weft wire pairs are offset from each other, d. H. the tying point of the first pair of weft wires and the eighth weft wire pairs are not under the same warp wire of the upper fabric layer.
