Definitions

  • the invention relates to a covering for paper machines made of a two or multi-layer fabric.
  • the individual fabric layers are connected to one another in that the longitudinal or transverse threads of one fabric layer are also tied at intervals with the transverse or longitudinal threads of another fabric layer.
  • the covering is in particular one for the sheet formation area of a paper machine.
  • Paper machine clothing of the type mentioned at the beginning, in which the fabric layers are not connected to one another by special binding threads, but rather by means of the so-called structural threads, are known (European application 44 053).
  • Such paper machine clothing can generally not be used for marking-sensitive papers, since at the binding points, that is, the places where the thread of one fabric layer is woven into another fabric layer, depressions or depressions are formed, which leave corresponding markings in the paper.
  • the invention has for its object to improve a paper machine clothing of the type mentioned with regard to the marking properties.
  • This object is achieved in that at least nigen longitudinal or transverse threads of a fabric layer, which are also interwoven with the transverse or longitudinal threads of another fabric layer, are carried out twice, with only one of the double longitudinal or transverse threads at a particular binding point with the transverse or longitudinal threads one at a time other fabric layer is woven.
  • the inventive design of a paper machine clothing reduces the force with which the upper fabric layer is pulled down at the tying points and is guided by the "normally" guided thread of a pair of threads, which is therefore not woven into the other fabric layer at the tying point between the fabric layers to maintain the structure of the paper side.
  • the force with which the two fabric layers are drawn towards each other at the binding points can be further reduced by alternately integrating the longitudinal or transverse threads in the other fabric layer.
  • one longitudinal or transverse thread of a pair of threads is woven into the other fabric layer, while at the next tying point, the other thread of the pair is woven.
  • the paper machine clothing generally relates to the sheet formation area of a paper machine since here there is primarily a risk of marking.
  • the paper machine clothing also generally has two fabric layers, it being the longitudinal or transverse threads of the upper layer, that is to say the paper side, which are also woven into the lower fabric layer, that is to say the running side, at intervals.
  • the two individual threads of the double longitudinal or transverse threads preferably have the same cross section.
  • the transverse threads in the upper fabric layer are at least as strong as the longitudinal threads and preferably even somewhat stronger.
  • This also applies to the paper machine clothing according to the invention, the total cross section of a double thread being used as the basis.
  • a double thread of the paper machine wire according to the invention thus has approximately the same total cross-sectional area as a cross thread of a paper machine wire according to the prior art.
  • the entire cross-sectional area therefore preferably remains unchanged. Deviations from this basic idea can be convenient in consideration of the fixing to the M onoplanmaschine the upper fabric layer to achieve.
  • the cross-sectional area of each individual thread of a double cross thread is only 30% smaller than the cross-sectional area of the longitudinal threads in the upper fabric layer.
  • the cross-sectional area of each individual thread of a double cross thread of the upper fabric layer is approximately between 50 and 70% of the cross-sectional area of a longitudinal thread.
  • the double cross thread can consist of two single threads, each between 0.13 and 0.15 mm.
  • the tying points at which one of the double cross threads of the upper fabric layer is interwoven with the longitudinal threads of the lower fabric layer are approximately between three and twelve longitudinal threads of the upper fabric layer, and preferably there are at least five longitudinal threads of the upper fabric layer between two tying points, so that the Duplicate cross threads are preferably guided in pairs over at least five longitudinal threads before they divide at a tying point.
  • the distance over which the double transverse threads are guided in pairs can be ten to twelve longitudinal threads, while with extremely heavily loaded paper machine screens, this distance can be reduced to three longitudinal threads.
  • the upper fabric layer is made with a higher warp number and weft number than the lower fabric layer, namely with twice the warp number and weft number.
  • the longitudinal threads and the transverse threads are preferably made of plastic wires, e.g. B. made of polyester or polyamide monofilaments. However, multifilaments are also used in some cases.
  • the individual fabric layers can have a plain weave, twill weave or satin weave or weaves derived therefrom.
  • the upper fabric layer, paper side can e.g. B. have a plain weave, while the lower fabric layer, running side, a four-twill weave can have long floats of the transverse threads visible on the running side.
  • threads running in the same direction are then double.
  • Cross threads double the cross thread of the pair, which is also integrated in the lower fabric layer, is included at each tying point between the double cross threads of the lower fabric layer and the longitudinal thread involved in the tying and is therefore almost completely removed from abrasion.
  • the single figure shows a cross section of a two-ply paper machine screen.
  • Cross threads 1 and longitudinal threads 2 together form the upper fabric layer 3 of the paper machine clothing or the paper machine wire. They are woven together in a plain weave. Longitudinal threads 5 and transverse threads 6 form the lower fabric layer 4, which were also woven in plain weave.
  • the upper fabric layer 3 has twice the number of longitudinal threads and transverse threads as the lower fabric layer 4 and the longitudinal threads 2 and the transverse threads 1 of the upper Ge Woven layer 3 are considerably thinner than that of the lower woven layer 4.
  • the cross threads 1 of the upper fabric layer 3 are double, i. H. instead of a cross thread, a pair of cross threads is woven.
  • the two transverse threads 1 of a pair have the same course with the exception of the binding point 7.
  • a cross thread la of the pair is bound into the lower fabric layer 4, while the other cross thread 1b remains in the upper fabric layer 3.
  • the two transverse threads la and lb of a pair of transverse threads separate.
  • the other cross thread 1b is preferably woven into the lower fabric layer 4, so the function of the two cross threads 1a and 1b is interchanged at each binding point 7.
  • the transverse thread 1b continues the binding pattern at the binding point 7 without interruption. It covers the tying point 7, so to speak.
  • the fact that only one transverse thread of a pair is involved in the lower fabric layer 4 at the binding point 7 also results in significantly smaller depressions or depressions at the binding points 7. Both effects together improve the marking properties of the paper machine screen.
  • the paper machine screen consists of two fabric layers 3, 4, each of which is individually woven from its own plastic wires, namely the upper fabric layer 3 made of warp wires 2 and weft wires 1 and the lower fabric layer 4 made of 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 Monofil Type 940.
  • the weft wires 1 are designed twice, with a weft wire density of 26 wire pairs per cm or 52 individual wires per cm. All weft wires in the upper fabric layer are double and consist of Trevira monofilament type 900 with a diameter of 0.13 mm (single wire).
  • the lower fabric layer also has a plain weave.
  • the warp number is 14.5 warp threads per cm with a diameter of 0.27 mm.
  • the warp threads are made of Trevira monofilament Type 940.
  • the weft wires of the lower fabric layer have a density of 13 threads per cm, have a diameter of 0.30 mm and consist alternately of Trevira monofilament type 900 and polyamide 6.6 monofilament.
  • the two fabric layers are connected in that a weft wire at a pair of weft wires of the upper fabric layer wraps around the warp wire of the lower fabric layer at regular intervals. This tying takes place with every eight warp wire of the upper fabric layer or every fourth warp wire of the lower fabric layer, so that the individual wires of each weft wire pair run together over a distance of 7 warp wires of the upper fabric layer.
  • every eighth weft wire pair of the upper fabric layer is involved in the tying, that is to say the 7 weft wire pairs of the upper one lying between them
  • Fabric layers are never tied with the warp wires of the lower fabric layer. For every eighth weft wire pair, one of the individual wires is tied with the warp wire of the lower fabric layer, while the other weft wire of the pair continues the normal weave unaffected, thereby avoiding the formation of a trough or depression at this binding point 7.
  • the tie points of the individual weft wire pairs are offset from each other, i. H. the binding point of the first pair of weft wires and the eighth pair of weft wires are not under the same warp wire of the upper fabric layer.
  • the finished fabric is provided with a dirt-repellent finish.
