Definitions

  • the invention relates to a composite fabric as a paper machine screen, consisting of a forming fabric and a wear fabric with at least three sets of longitudinal threads and at least two sets of transverse threads.
  • DE-OS 29 17 694 describes a forming fabric for paper machines, consisting of a first set of warp threads and a first set of weft threads that are woven together to form a first complete fabric, and a second set of warp threads and a second set of weft threads that are woven into a second complete fabric.
  • the said first fabric and the second fabric are to be bound together by special weft threads located between the fabrics, which bind with threads from the first and second sets of warp threads.
  • the aim pursued there is to make the binding weft threads run fairly straight in the fabric body, whereby they are wrapped in warp threads of the upper and lower fabrics, whereby the binding points should lie in the fabric body and not on its outer threads and therefore do not affect the flatness of the paper side not achieved with this known sieve.
  • the binding weft threads do not run straight, but are heavily cranked and form on the paper side of the screen with the weft threads of the upper fabric regularly arranged double offsets that draw depressions into the surface, which even include adjacent offsets.
  • this does not eliminate the disadvantages mentioned at the outset, namely the strong markings, which are intolerable for many types of paper, in particular for fine papers.
  • the object of the invention is therefore to design the paper machine screen of the type mentioned at the outset, which should preferably be used for the production of fine papers, in such a way that the marking problem is finally eliminated.
  • At least half of all the outer longitudinal cranks of the forming fabric of the screen are formed from at least two longitudinal thread sets, in that the first longitudinal thread set with the first transverse thread set, the third longitudinal thread set with the second transverse thread set and at least parts of the second longitudinal thread set with both Cross thread sets are interwoven, and that at least along a portion of the threads of the first longitudinal thread set, the double offsets are formed from one thread of the first longitudinal thread set and two threads of the second longitudinal thread set, these two threads of the longitudinal thread set alternating with one another in the formation of the double offsets.
  • the paper machine screen according to the invention thus forms a composite fabric with double offsets.
  • all the outer longitudinal cranks of the upper fabric are formed from the first and the second longitudinal thread set.
  • the offset distribution of the upper fabric and / or the lower fabric can correspond to a linen weave, and, according to a further embodiment of the invention, transverse threads can additionally be woven into the lower fabric, which span at least three longitudinal threads to the outside. These additionally woven cross threads can consist of a highly wear-resistant material.
  • the lower fabric can also be woven in Batavia weave.
  • first and second warp or longitudinal thread sets 1 and 2 are interwoven with the first weft or transverse thread set 4 to form a so-called simple weave, in which all outwardly shaped longitudinal cranks are formed from a warp thread 1 and a warp thread 2, as a result of which the exercise by them Pressure on the weft threads spanned by them is the same at all points. So there are no offsets that are exposed to increased tension and therefore no depressions in the forming fabric that could cause marks in the paper.
  • connection of the upper fabric and the lower fabric is made by the thread pairs 7 and 8 from the longitudinal thread set 2, which alternately bind in the lower fabric.
  • the threads 9 from the longitudinal thread set 2 are not woven into the lower fabric, but could be replaced at any time by thread pairs 7 and 8.
  • FIGS. 2 and 2a show a preferred construction of a wear fabric, to which a group of transverse threads 6 made of highly wear-resistant material has been integrated. These wear threads 6 form long offsets spanning three longitudinal or warp threads and thus improve the weft properties of the wear fabric.
  • cranks x of the forming fabric but also the cranks y of the wearing fabric are double cranks, the number of stitches of the forming fabric being four times as large as that of the wearing fabric. It is these cranks y that illustrate the extraordinarily high number of tie points.
  • FIGS. 4 and 4a Such a combination is shown in FIGS. 4 and 4a.
  • the wear fabric is woven in Batavia weave.
  • the set of binding threads consists only of thread pairs 7 and 8.
  • the number of binding threads is thus twice as large as the number of warp threads of the upper fabric. It even exceeds the sum of all longitudinal or warp threads 1 and 3 of the two fabrics.
  • the number of stitches in the forming fabric is four times as large as that in the wear fabric.
  • the number of binding threads is always substantially smaller than the number of threads of the forming fabric running in the same direction, this number of binding threads in the fabric according to the invention is larger, for example, as explained above, twice as large.
  • all of the external offsets of the longitudinal or warp threads of the upper or forming fabric are woven twice, whereby all offsets of this fabric and not just a few are disturbed in the same way.
