Definitions

  • the invention relates to a papermaking wire, in particular a forming fabric, according to the preamble of patent claim 1.
  • Such a paper machine screen is for example from the document US 5,826,627 known.
  • Paper machine screens are subject to a great variety of requirements.
  • the paper-facing paper side of the screen in particular for the production of graphic papers, must have a finely structured surface with as few marking points as possible, which are often formed by so-called binding diagonals.
  • the run side of the papermaking fabric on the other hand, must have a coarse, high wear volume structure to maximize machine direction and force absorbing filaments for maximum durability.
  • papermaking fabrics have been developed with a paper-side fabric and a running-side fabric bonded thereto by means of binding threads.
  • EP 1 294 981 A1 is known a papermaking machine, which has a trained in plain weave paper-side fabric and in which each Laufucirapport in the warp direction each two crossing points of the binding threads are formed when changing between the weaving with the paper side and the running side fabric.
  • plain weave the warp bumps are on mutually parallel extending diagonals arranged, which has an increased marking of the paper formed on such a tissue result.
  • EP 1 746 202 A1 describes a method for producing a papermaking fabric in which a specific Schafeinzugsschema the warp threads is realized.
  • the two pamphlets WO 99/61698 A1 and WO 2006/083604 A1 (not prepublished) disclose paper machine fabrics, in which the course woven by binding threads on the paper side is significantly shorter than the paper-side repeat of the binding threads.
  • the papermaking fabric according to the invention is characterized in that the arrangement of the binding thread elevations and depressions in the upper rapport forms an irregular pattern.
  • a high binding frequency is created between the upper or paper side and the lower or running side fabric, whereby a stable connection between the paper side and the running side fabric is provided.
  • intersection points can be distributed more irregularly than is possible with the paper machine fabrics known from the prior art, which in particular reduces the visibility of markings produced by different hydraulic dewatering pressure becomes.
  • the upper fabric layer is formed only by the weaving of the upper transverse threads with the binding threads.
  • the upper fabric layer is formed by the weaving of the grouped binding threads with the upper transverse threads and by the weaving of upper longitudinal threads with the upper transverse threads.
  • the upper longitudinal threads are woven only with the upper transverse threads, which is why everyone upper longitudinal thread when weaving with the upper transverse thread forms an upper longitudinal thread course.
  • the upper fabric layer is irregular. If the upper fabric layer is formed by interweaving the binding threads with the upper transverse threads, then each upper longitudinal thread course formed by a group of binding threads comprises longitudinal thread bumps and longitudinal thread bumps. In this case, a longitudinal thread lift is formed by the binding yarn of a group weaving in each case above the upper transverse threads crossing an upper transverse thread continuously on the outside of the upper fabric layer. A longitudinal thread reduction is formed in this case by the respective upper transverse threads weaving binder thread of a group between upper and lower fabric layer continuously crosses an upper transverse thread.
  • the upper fabric layer is additionally formed by the interweaving of upper longitudinal threads with the upper transverse threads, then longitudinal thread elevations are formed by the upper longitudinal thread continuously crossing an upper transverse thread on the outside of the upper fabric layer. Furthermore, longitudinal thread decreases are formed by the upper longitudinal thread between the upper and lower fabric layers continuously crossing an upper transverse thread.
  • the irregular pattern of the upper fabric layer can be formed by at least two L Lucassfadenverstructure are formed in the upper repeat that one of the two Leksfadenverstructure not by displacement of all its longitudinal thread elevations and depressions by an equal number of upper transverse threads in the longitudinal direction of the can produce other of the two longitudinal thread courses.
  • the upper repeat comprises at least two longitudinal thread courses in which one of the two longitudinal thread courses can not be produced by offsetting all of its longitudinal thread elevations and dips by an equal number of upper transverse threads in the longitudinal thread direction from the other of the two longitudinal thread courses, the number of Binding diagonals and regular structures on the paper side reduced, resulting in a reduction of the marking of the paper machine screen produced with the paper.
  • the upper weave pattern has an irregular structure in that none of the upper longitudinal thread courses in the upper repeat by offset all its longitudinal thread elevations and longitudinal thread descents by a same Number of upper transverse threads in the longitudinal direction of the thread can be generated from another upper longitudinal thread course of the repeat.
  • bonds are called creping bonds.
  • the upper fabric layer preferably comprises upper transverse threads or upper transverse threads and binding threads which have a diameter in the range of 0.03 to 0.5 mm, preferably 0.08 to 0.15 mm.
  • the irregular pattern is formed by the upper repeat has a first upper longitudinal thread course, an immediately adjacent second longitudinal thread course and the second immediately adjacent third longitudinal thread course, which are formed such that the Offset of the longitudinal thread elevations and longitudinal thread descents of the second longitudinal thread course relative to the longitudinal thread elevations and depressions of the first longitudinal thread course is not equal to the offset of the longitudinal thread elevations and longitudinal thread elevations of the third longitudinal thread course relative to the longitudinal thread elevations and depressions of the second longitudinal thread course.
  • the irregular paper-side weave structure can also be provided by the fact that the upper weave structure comprises a number of mutually different longitudinal thread runs, wherein the number of mutually different longitudinal thread runs is less than the number of longitudinal thread runs forming the upper repeat.
  • the mutually different longitudinal thread paths are arranged in a non-repetitive order over the entire upper repeat.
  • the resulting longitudinal thread repeat can then be very large, for example, 12 longitudinal thread courses include, wherein the number of mutually different longitudinal thread paths, for example, is only four. This means that a very large binding can be woven with only a small number of shafts for the paper side.
  • the order of the longitudinal thread courses can, for example, be as follows: 1-2-3-1-4-1-2-3-4-2-3-1
  • the number of longitudinal thread bumps and longitudinal thread bumps in the upper repeat is substantially the same.
  • the paper side is dominated neither by longitudinal thread elevations nor by longitudinal thread reductions, so that a result in the plane paper page with irregular structure and resulting, with even further reduced marking tendency is created.
  • another particularly preferred embodiment of the invention provides that none of the longitudinal thread courses in the upper repeat by offset all its longitudinal thread elevations and depressions by an equal number of upper transverse threads in the longitudinal direction of a different thread Create longitudinal thread course. This means that each longitudinal thread course in the upper repeat in its L jossfadenhebungs- and lowering sequence is different from the other L jossfadenverêtn.
  • the irregular structure of the upper fabric layer can be formed alone or in combination by: Free textile development, alteration of a textile basic weave, derivation of a textile basic weave, extension of a textile basic weave.
  • the reduction of the marking tendency can be further reduced if the paper-side repeat is large, i. is formed from at least 14 upper transverse threads.
  • the tendency to mark can be significantly reduced, since the spacing of regularly arranged longitudinal thread elevations increases as a result of the enlargement of the repeat.
  • a preferred embodiment of the invention provides that a maximum of three, preferably a maximum of two paper-side longitudinal thread elevations are arranged adjacent to each other immediately adjacent to each upper longitudinal thread and that a maximum of three, preferably a maximum of two paper-side Leksfadensenkept are arranged adjacent to each other directly.
  • a ratio of upper to lower transverse threads greater than 1 it is possible to provide a papermaking fabric interconnecting a fine, ie non-marking, paper side and a coarse and wearable running side because, on the one hand, the paper-side fabric by more transverse threads is formed as a 1 to 1 ratio and on the other hand for the running side fabric running side transverse threads with a larger thread diameter can be used than in a 1 to 1 ratio.
  • each lower transverse thread is held by a plurality of binding threads by each of these binding threads on the outside of the lower fabric layer continuously crosses the respective lower transverse thread, wherein some of the respective lower transverse thread holding binding threads by at least one of the respective lower Transverse thread non-retaining binding threads are spaced from each other by the non-retaining binding thread not on the outside of the lower fabric layer continuously crosses the respective lower transverse thread, and wherein a plurality of lower transverse threads are provided, in each case between successive, the respective lower transverse thread holding binding threads an equal Number of non-retaining binding threads is arranged.
  • the holding force can furthermore be uniformly distributed, as a result of which a significantly stronger connection between the two fabric layers can be achieved, as a result of which their relative movement to one another can be reduced to a minimum, which leads to a minimization of the internal wear of the paper machine wire according to the invention ,
  • the uniform distribution of the binding sites and the possible stronger attachment of the upper to the lower fabric layer leads to a reduced total thickness of the paper machine fabric according to the invention in comparison to the screens known from the prior art.
  • an equal number of binding threads not holding the transverse thread are arranged for each lower transverse thread between successive binding threads respectively holding the lower transverse thread.
  • the number of binding threads not holding the respective transverse thread is between two and twenty, preferably between six and ten. Tests have shown that with the same float lengths of between two and twenty binding threads not holding the respective lower transverse thread a good connection between upper and lower fabric layer can be provided, coupled with improved wear resistance, in particular for use in paper machines at speeds of 1500 m / min or more.
  • the overall repeat is preferably formed by a multiplicity of longitudinal threads and / or upper and lower transverse threads.
  • the overall repeat of the papermaker's fabric may include, for example, 24 or more or 26 or more or 32 or more or 48 or more longitudinal thread courses and / or 24 or more or 26 or more or 32 or more or 48 or more top and bottom transverse threads.
  • the marking tendency of the paper side can be significantly reduced by the upper fabric layer having an upper repeat formed by 24 or more longitudinal thread courses and by 24 or more upper transverse threads.

  • the paper-side longitudinal thread repeat A is therefore formed from 16 upper transverse threads.
  • the two binding threads B1a, B1b are interwoven in sections alternately with lower or running transverse threads L1 to L8, which are also weft threads, and form a running-side longitudinal thread course 10 during weaving with the running side transverse threads L1 to L8, resulting in running longitudinal thread reports B repeated.
