Definitions

  • the invention relates to a paper machine screen, in particular for the sheet formation zone, with a paper and a running side, made up of at least a kind of cross threads and at least one kind interwoven with them Longitudinal threads that at least form reports with each other form two different types at intersections, using the weave pattern formed from the longitudinal and transverse threads of the paper side itself repeated between intersections of the same type and being between the two crossing points of the same type and with the formation of each another type at the intersection, the longitudinal threads from the running side to the Change paper side and vice versa.
  • the sheet formation unit is in usually designed as a twin-wire form, in many cases also as a gap former. It is characteristic of the machines that the sheet formation process immediately between two paper machine screens in a relatively short drainage zone takes place. Because of 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 matter content the fiber suspension increased from approximately 1% to approximately 20% become. For paper machine screens, this means that they are very high However, drainage capacity does not have to have any markings allowed to leave in the paper and offer high fiber support.
  • a related composite fabric is described for example in DE 42 29 828 C2.
  • the known paper machine screen consists of two superimposed Sieve fabrics that are formed at least in one layer and by binding threads running in the transverse and / or longitudinal direction are connected to one another are, with one of the screen fabrics as a definition fabric with the mechanical properties of the composite fabric with regard to elongation and stiffness of certain formation and the other screen cloth as the reaction cloth with a higher elongation and less stiffness than the definition fabric is executed.
  • binding threads do not belong to the fabric structure, but are independent components, they are as large as possible in diameter kept thin to only slightly disrupt drainage. With accordingly high loads there is then the possibility that tear the thin binding threads and the bond between the sieve fabrics comes loose.
  • binding threads in a generic paper machine after EP 0 432 413 B1, which is also constructed as a composite fabric, is already suggested binding threads as two of the fabric's own threads to use and this in formation of X-shaped intersections to weave the other fabric layer to the disadvantages described to avoid in the prior art; solely by the accumulation of the Known exchange points in the transverse direction also unintentionally arises Stiffening of the known fabric.
  • the object of the invention is based on paper machine screens of the aforementioned type improve that they have a longer service life in papermaking and secondly, they can be implemented cost-effectively.
  • a pertinent one A paper machine screen solves the problem with the features of the claim 1.
  • a shot ratio is preferably chosen from 2: 1.
  • the figures partially show a screen fabric designated as a whole by 10 for a paper machine screen, not shown as a whole, in particular can be used for the so-called sheet formation zone in conventional paper making machines.
  • the screen fabric 10 has a paper side 12 and one Running page 14.
  • the relevant 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 longitudinal threads 20 woven with them both seen in the longitudinal direction and in the transverse direction on the screen fabric 10 8-strand repeats A to H made in this repeat pattern Repeat lengthways and crossways accordingly.
  • the weave pattern repeats formed from the longitudinal threads 20 and transverse threads 16 of the paper side 12, between Crossing points 22 of the same type, being between the two crossing points 22 of the same type and with the formation of the further or another type at intersection points 24, the longitudinal threads 20 from the running side 14 switch to paper page 12 and vice versa.
  • the solution is to change the longitudinal threads 20 in the difference to the state of the art with formation of the further type at intersection points 24 within the respective repeat A to H of the running side 14 of the screen fabric 10.
  • this repeat A to H of the running side 14 on its side facing away from the paper side 12 Outside 26 the transverse threads 18 of the running side 14 of at least two longitudinal threads 20 held.
  • Binding it becomes possible to face the number of shots on paper side 12 to double the running side 14 shown. Accordingly, it follows a 2: 1 shot ratio between paper side 12 and barrel side 14 while in the known solutions usually a shot ratio of only 1: 1 is achieved.
  • the thread diameters which can thus be installed on the running side 14, can thus be doubled in cross-section compared to the paper side 16 become. That in turn means that the volume of the wearing Material (deficit) and thus the running time of the sieve according to the invention on the one hand through the long-floating bond achieved and on the other significantly increased by the larger diameter on the running side 14 can be. Due to the "open" running side 14 reached, in addition the permeability of the screen fabric 10 is increased and so are the drainage properties clearly improved.
  • the screen fabric 10 according to the invention is largely has a homogeneous binding pattern and a safe, equally effective Bonding is achieved in every direction of the fabric.
  • the bond pattern the paper side 12 consists of a normal plain weave, the plain weave that is between intersections of the one type 22 and the immediately following other type 24, 8-stemmed is trained. Furthermore, it is provided that the running side 14 within each repeat A to H, 8 strands in both directions considered trained.
  • the respective longitudinal threads 20, the cross threads 18 of the running side 14 support their outer side 26 facing away from the paper side 12, at least once adjacent in pairs (see Fig. 3) side by side arranged.
  • the transverse threads 16, 18 as weft threads and the longitudinal threads 20 as warp threads train As FIG. 1 in particular shows, the crossing points are one type 22 on the running side 14 of two cross threads 18 and the crossing point the other type 24 of four transverse threads 18 towards the running side 14 considered supported, these supporting transverse threads 18 essentially in a common plane on the outside 26 of the running side 14 are arranged horizontally.
  • the respective longitudinal threads 20, which are the transverse threads 18 Running side 14 on its side 28 facing paper side 12 (see FIG. 2) limit, grouped in pairs next to each other, whereby up to three Groups in the immediate neighboring facility within a repeat A to H can be present (see transverse thread 18D in Fig. 2).
  • the plain weave on paper page 12 there would also be another, regular Repetitive binding pattern conceivable for the solution.
  • paper side 12 and running side 14 is a unified tissue and no longer, as in the prior art Technology, a composite fabric made of separable individual fabrics.
  • the paper machine screen is nevertheless built up in several layers and could in the sense of a composite fabric also expanded accordingly with fabric layers become.
