Definitions

  • the invention relates to a covering for paper machines made of a fabric with two or more fabric layers, each of which is a complete fabric made of interwoven structural longitudinal and transverse threads.
  • the individual fabric layers are connected to each other by additional binding cross threads.
  • the coverings are in particular those for the sheet formation area of a paper machine.
  • Such coverings for paper machines are known from DE-OSes 24 55 184, 24 55 185 and 29 17 694.
  • the binding transverse threads pose difficulties; If the binding cross threads are woven in with high tension and accordingly bind the two fabric layers tightly to one another, deep troughs occur at the binding points of the upper fabric layer. H. on the paper side. If, on the other hand, the bandage transverse threads are loosely woven in, they are rubbed through relatively quickly, both on the running side and between the fabric layers.
  • the invention has for its object to provide a covering of the type mentioned for paper machines in which the binding cross thread on the one hand does not cause troughs on the paper side and on the other hand is not prematurely rubbed on the running side or between the fabric layers.
  • binding cross threads between the double structural cross threads and the respective longitudinal thread is further improved in that the binding cross thread has a smaller diameter than the double structural cross threads.
  • Claim 3 is directed to a paper machine clothing in which both inventions are realized.
  • the covering according to the invention is generally only two layers, the upper fabric layer being finer woven than the lower fabric layer.
  • the warp number and the weft number of the lower fabric layer is that the running side is only half as large as that of the upper fabric layer.
  • the covering according to the invention usually consists of plastic wires made of the usual material for paper machine clothing, e.g. B. polyester and polyamide.
  • the covering can be open or endless woven. In the open weave, the cross threads are the weft threads, while in the endless weave they are the warp threads.
  • the basic idea of the invention can also be applied to longitudinal threads of the binding, in which case the longitudinal threads which bind together with them are each duplicated.
  • a binding transverse thread 3 also binds with the longitudinal thread 1.
  • the binding transverse thread 3 has a substantially smaller diameter than the structural transverse thread 2.
  • the central axes of the binding transverse thread 3 and the structural transverse thread 2 are approximately at the same height, i. that is, after a relatively short period of time, the binding cross thread 3 is also exposed to wear. Because of its smaller diameter, it will be destroyed in front of the structural cross thread 2.
  • By tightening the binding cross thread tighter it can be slightly raised, i. H. are shifted towards the paper side, but then he exercises too strong downwards on the longitudinal threads with which he is tied in the upper fabric layer, i. H. directed force towards the running side, so that troughs form in the upper fabric layer and the marking properties of the covering are impaired.
  • binding cross thread With some bindings, e.g. B. three-twill weaves and drap weaves, it is possible to arrange the binding cross thread on the running side between two structural cross threads of the lower fabric layer, as shown in Fig. 2.
  • the binding cross thread is then largely removed from abrasion, but has no lateral hold. Its mobility transversely to its longitudinal direction enables the two fabric layers to be displaced relative to one another, which leads to unnecessary wear on the adjoining surfaces of the two fabric layers.
  • the structural transverse threads 2 are each arranged in pairs, and the binding transverse thread 3 is pressed onto the highest point of the arch of the structural longitudinal thread 1 without any particular tension being exerted on it. At this point it is removed from abrasion. This means an increase in the running time of the paper machine clothing, since the material of the structural longitudinal and transverse threads of the lower fabric layer is completely used up without the two fabric layers separating.
  • the binding cross thread 3 exerts a lower, downward force on the structural longitudinal threads with which it is interwoven in the upper fabric layer, so that there are no or only slight troughs on the paper side.
  • the paper machine screen consists of two fabric layers, which are complete fabrics in themselves and are connected to each other with the help of additional connecting weft wires.
  • Both fabric layers are woven open, so that the warp wires are the longitudinal threads and the weft threads are the transverse threads.
  • the upper fabric layer has a plain weave and shows 28 warp wires per cm.
  • the warp wires have a diameter of 0.17 mm and are made of polyester monofilament, type Trevira 940.
  • the number of wefts in the upper fabric layer is 24 weft wires per cm.
  • the weft wires have a diameter of 0.20 mm and are made of polyester monofilament, type Trevira 900.
  • the lower fabric layer also has a plain weave and has 14 warp wires per cm.
  • the warp wires have a diameter of 0.30 mm and are made of polyester monofilament, type Trevira 940.
  • All weft wires in the lower fabric layer are designed as double wires and the weft density is 12 wire pairs per cm, i.e. 24 individual wires per cm.
  • the diameter of the weft wires is 0.25 mm in each case.
  • the material of the two individual wires of each pair of weft wires is different and one weft wire is made of polyester monofilament, type Trevira 900 and the other of polyamide 6.6 monofilament.
  • the binding weft wires that connect the two fabric layers with each other have a diameter of 0.17 mm and are made of polyester monofilament, type Trevira 900.
  • the binding weft wires are woven in after every fourth weft wire of the upper fabric layer.
  • the tying points are diagonally offset from each other in the direction of travel, so that the binding weft only binds to the same warp wire of the upper fabric layer again after 12 weft wires of the upper fabric layer.
  • the use of double weft wires in the lower three layers of fabric binds the binding weft wire between the two weft wires of a pair of weft wires and the warp wire, as shown in FIG. 3.
  • the two weft wires of the pair press the binding weft wire into the warp wire in the lower fabric layer so that all three weft wires are jointly involved in the deformation of the warp wire.
  • the binding weft wire is embedded in the warp wire at a relatively large distance from the abrasion plane.
  • the two structural weft wires of the lower fabric layer are first looped through. Then the warp wires of the lower fabric layer loop through. In this way, the binding weft wires can hold together the remnants of the warp wires of the lower fabric layer, that is, even if the running side of the paper machine screen has already been ground through.
