Definitions

  • the invention relates to a paper machine screen, consisting of an upper fabric of any type of weave and a lower fabric of any type of weave, both of which are equipped with their own system of binding threads.
  • Multi-layer screens and composite fabrics in particular paper machine screens, in which the individual screen layers or fabric layers are connected to one another by a binding chain or a binding weft, have long been part of the prior art (DE-PS 24 55 185, DE-PS 29 17 694) .
  • a two-layer forming fabric consisting of upper fabric and lower fabric
  • a single-layer screen in plain weave is used as the upper fabric
  • a double-layer lower screen is used as the lower fabric.
  • the connection between the top and bottom sieve is made both with a weft thread of the bottom sieve and with a separate binding weft.
  • the object of the invention is to further improve the progress achieved so far in the field of binding technology between the various layers of such fabrics with regard to the properties specified above.
  • binding thread systems are themselves connected.
  • the use of the binding thread systems themselves as connecting elements between the individual fabric layers of sieve belts not only opens up a wide range of possibilities for even more special adaptation of such multi-layer sieves to the specific application or intended use and the prevailing conditions of use, since the binding systems as separate components meet the special requirements of the binding qualities can be produced adapted, but also increases the life of such screens or composite fabrics.
  • Advantageous embodiments of the invention are characterized in the subclaims.
  • the system of crossing binding threads can be both an independent fabric and a scrim.
  • a scrim is understood to mean a system of longitudinal threads 1 and transverse threads 2, which are not interwoven, but are placed one above the other, as can be seen from FIG. 1. Above such a system is an upper fabric (not shown) of any type of weave and beneath the same is a not shown weave of any type of weave.
  • a multi-layer system of this type can also be used.
  • binding thread system forms a scrim or a fabric, wherein several scrims and / or fabrics can also be used as part of the binding thread system, although these cases are not shown in the drawing.
  • the transverse thread 2 of the multiple layer is woven into the upper fabric, and the transverse thread 3 is woven into the lower fabric.
  • the cross thread 4 is not woven with either the upper or the lower fabric. Part of the longitudinal threads 1 is bound into the lower fabric and part into the upper fabric.
  • Twine that does not bind to either the upper or the lower fabric is assigned to the fabric with which the twine system is woven.
  • the thread 7 in FIG. 4 is assigned to the binding thread system of the lower fabric.
  • this thread group forms a multiple fabric with both binding thread systems or it creates a fabric with both binding thread systems. In both cases, this thread group serves to connect the two binding thread systems, which would otherwise remain separate.
  • the binding thread system forms a separate sieve, in which one thread group 6 binds into the upper fabric and the other thread group 5 into the lower fabric.
  • FIG. 4 The possibility already mentioned above that a part of the threads of the binding thread system does not bind into the upper or lower tissue is shown in FIG. 4 indicated by the formation and course of the Ouer thread 7. Only the longitudinal threads 5 and the outer threads 6 are connected to the lower and upper fabrics.
  • binder yarns of the binder yarn systems may consist of spirals, further wherein at least a portion of the spirals may be ausoe according as Dopoelspiralen, which then advantageously consist of polyamide and polyester .
  • Such binder thread systems which form an intermediate fabric and / or intermediate layer, connect the upper fabric to the lower fabric of the paper machine screen in a manner which not only improves the quality of the paper produced on it, but also the quality of the screen itself, by in the case of plastic screens, it promotes a compensation of the sooting that occurs during heat setting.
