Definitions

  • the invention relates to a composite fabric as a paper machine screen according to the preamble of claim 1.
  • the object of the invention is therefore to design the composite fabric of the type mentioned in such a way that it has a new type of lower fabric, with the aid of which the above-mentioned disadvantages are eliminated.
  • the lower fabric contains two groups of transverse threads, the first of which are interwoven in 1: 1 weave and the second in 1: n weave with the warp threads of the lower fabric, that successive transverse threads of different types of weave, based on form double offsets on the inside of the lower fabric, touch, and that the long n offsets form a wear plane on the outside, where n means odd numbers greater than 1.
  • the weave of the lower fabric is therefore determined in such a way that part of the transverse threads is interwoven with the longitudinal threads in a 1: 1 offset ratio and the other part in a 1: n offset ratio, where n is the number of longitudinal threads that are on the running side, i.e. the outside, spanned by the cranks of the 1: n cross threads.
  • n is the number of longitudinal threads that are on the running side, i.e. the outside, spanned by the cranks of the 1: n cross threads.
  • the inner sides of the lower fabric of known composite screens are shown; the bumps 1, 2 and 3 are the contact points for the upper fabric. Since the longitudinal threads should not be exposed to wear, since otherwise the longitudinal stability is lost very quickly, the overlaps are generally transverse crankings.
  • Fig. 4 shows the inside of the lower fabric according to the invention. Since the upper fabric of the composite sieve according to the invention also has a simple weave, the contraction values can be coordinated with one another in such a way that no significant stresses arise between the upper and lower fabrics, regardless of the weft-running properties of the wear side of the lower fabric. Such composite screens therefore do not tend to form wrinkles.
  • the bottom fabric of the composite sieve according to the invention has 12 cross-bends 4, 5 on its inside, since this bottom fabric can be designed such that the longitudinal bends 6 and cross-bends 4, 5 of the inside lie almost in the same plane without the weft-running property of the barrel side being lost, the number of support points can be increased to 72. Practice shows, however, that 12 crossbends are sufficient as support points.
  • 5 and 6 the running sides of two composite screens according to the invention are shown. In the running side of FIG. 5, the wear thread 7 spans five longitudinal threads. The cranks are distributed so that they form left and right diagonals at the same angle. This particularly stabilizes the straight running of the paper machine screen.
  • the transverse cranks 8 extending over three longitudinal threads are distributed in a cross-body manner, as a result of which the same effect is achieved.
  • the number of 1: 1-bound cross threads is larger than that of 1: 3-bound cross threads.
  • FIG. 7 shows a complete composite screen of the type according to the invention, consisting of a fine, simple top fabric 9 and a coarse bottom fabric 10 of the type shown in FIG. 4. However, to illustrate the structure, the top fabric is only shown in part.
  • connection between the upper fabric and the lower fabric is made with weft threads 11. This binding technique is known per se.
  • FIGS. 8 and 9 The running side of the composite fabric according to the invention is shown in FIGS. 8 and 9, with FIG. 9 in particular showing the protrusion a of the wear threads over the longitudinal threads. It can be seen from this illustration that the wear cranks can wear out completely without the longitudinal threads being attacked, as a result of which the desired long running times of the paper machine screen are achieved.
  • FIG. 10 shows a possibility of breaking the diagonal formed by the wear offsets by attaching a binding cartridge B with a Z-diagnosis to the binding cartridge A with an S-diagonal.
