Definitions

  • the invention relates to a papermaking fabric, in particular for the sheet forming zone, having a paper and a running side, formed from at least one type of transverse threads and at least one type with these interwoven longitudinal threads, which together form at least two different types of crossing points to form reports, wherein the weave pattern formed from the longitudinal and transverse threads of the paper side is repeated between intersections of the same kind and wherein between the two intersection points of the same kind and forming the respective other type of intersection, the longitudinal threads from the running side to the paper side and vice versa.
  • the sheet forming unit is usually designed as a double screen, in many cases as a gap former. Characteristic of the machines is that the sheet forming operation takes place immediately between two paper machine wires in a relatively short dewatering zone. Due to this short distance and the high production speed, the time for sheet formation is reduced to a few milliseconds. During this period, the solids content or dry content of the pulp suspension must be increased from about 1% to about 20%. This means for the paper machine sieves that they must have a very high dewatering performance but still can leave no marks in the paper and provide a high fiber support.
  • a pertinent composite fabric is for example in the DE 42 29 828 C2 described.
  • the paper machine screen known in this respect consists of two superimposed screen fabrics, which are formed at least one ply and connected by transversely and / or longitudinally extending binding threads, wherein one of the screen fabric as a definition fabric with the mechanical properties of the composite fabric in terms of elongation and rigidity of certain training and the other Screen fabric is designed as a reaction fabric with a higher elongation and lower stiffness than the definition fabric.
  • the mentioned screen fabric thus consist of warp and weft threads, which are connected by additional binding threads together.
  • Siebgewebelagen As a reaction or definition fabric the inner wear and in particular the wear of the binding threads is counteracted and thus increases the life of the composite fabric and an unwanted separation of Siebgewebelagen avoided even in the longer term.
  • the mentioned internal wear of a composite fabric is due in particular to the fact that in the screen deflections, as they occur in the region of guide rolls of the wire section over which the composite fabric is guided, the individual fabric layers are stretched or compressed to varying degrees.
  • binding threads do not belong to the fabric structure but are components of their own, they are kept as thin as possible in diameter in order to disturb the drainage only slightly. With correspondingly high stresses then there is the possibility that the thin binding threads tear and the bond between the meshes dissolves.
  • a paper machine after the EP 0 432 413 B1 which is also constructed as a composite fabric and has the features mentioned in paragraph [0001]
  • binding threads as two tissue-own threads and weave them to form X-shaped intersections in the respective other fabric layer to those described
  • US-A-5,865,219 discloses a two-ply papermachine fabric having a first layer of transverse filaments, a second layer of transverse filaments, and longitudinal filaments interwoven with the two transverse filament layers, the fabric repeating after eight transverse filaments.
  • EP-A-0 224 276 discloses a fabric for the sheet forming part of a paper machine, which is formed of a double-layered fabric with an upper and lower layer of transverse threads which are interwoven with longitudinal threads. The transverse threads of the upper layer and the longitudinal threads thereby form to the paper side directed offsets, the highest points in a plane, the plane of the paper lie.
  • the present invention seeks to further improve paper machine fabrics of the aforementioned type such that they have longer life in papermaking and on the other can be realized cost-effectively.
  • This object is achieved by a paper machine screen having the features of claim 1.
  • the transverse threads of the running side in cross-section thicker than the transverse threads of the paper side and yet to ensure their secure fit in the paper machine screen.
  • a shot ratio of 2: 1 is selected.
  • the long-running running side with weft threads widened in cross-section moreover maximizes the transit time potential for the papermaking screen and nevertheless achieves high lateral stability due to the two separate weft layers.
  • the figures partially show a screen fabric designated as a whole by 10 for a paper machine wire, not shown as a whole, which can be used in particular for the so-called sheet forming zone in conventional papermaking machines.
  • the screen fabric 10 has a paper side 12 and a running side 14.
  • the pertinent paper side 12 and the running side 14 are formed from two different types of transverse threads 16,18 and at least one type with these interwoven longitudinal threads 20.
  • the transverse threads 16,18 form with the interwoven longitudinal threads 20 both in the longitudinal direction and in the transverse direction seen on the screen fabric 10 8-repeating rapport A to H, which repeat in this repeat pattern in the longitudinal and transverse directions accordingly.
  • the weave pattern formed by the longitudinal yarns 20 and transverse yarns 16 of the paper side 12 is repeated between intersections 22 of the same type, wherein between the two intersections 22 of the same kind and forming the respectively further or other type at intersections 24 the longitudinal threads 20 from the running side 14 to the paper side 12 and vice versa.
  • the longitudinal threads 20 takes place in contrast to the prior art to form the other kind at intersections 24 within the respective rapport A to H of the running side 14 of the screen fabric 10.
  • the transverse threads 18 of the running side 14 of at least two longitudinal threads 20 held.
  • the thread diameter which can thus be installed on the running side 14, can be doubled in cross-section relative to the paper side 16. This in turn means that the volume of the wear material (undershoot) and thus the life of the screen according to the invention can be significantly increased once by the achieved long-floating binding and on the other by the larger diameter on the running side 14.
  • the permeability of the mesh fabric 10 is further increased and so significantly improves the drainage properties.
  • the weave pattern of the paper page 12 consists of a conventional plain weave, the plain weave between Crossing points of a kind 22 and the immediately following other type 24 runs, 8-trained trained. Furthermore, it is provided that the running side 14 is formed within each repeat A to H 8-Mftig considered in both directions.
  • the respective longitudinal threads 20, which support the transverse threads 18 of the running side 14 on their outer side 26 facing away from the paper side 12, are adjacent in pairs at least once (cf. Figure 3 ) arranged side by side. Manufacturing technology, it has proved to be particularly advantageous to form the transverse threads 16,18 as weft threads and the longitudinal threads 20 as warp threads. How the particular Fig.1 2, the intersections of one type 22 on the running side 14 are supported by two transverse threads 18 and the intersection point of the other type 24 by four transverse threads 18 towards the running side 14, these supporting transverse threads 18 being substantially in a common plane on the outside 26 the running side 14 are arranged lying.
