Definitions

  • the invention relates to a forming fabric for the wet end of a paper machine, consisting of at least two complete fabrics of any type of weave, which are woven together with longitudinal and / or transverse binding threads, the longitudinal threads of the fabrics forming longitudinal fiber support points and the transverse threads forming transverse fiber support points.
  • 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 known (DE 24 55 185, DE 29 17 694).
  • Such screens are used to make a wide variety of papers, from kraft paper to cigarette and condenser papers. It goes without saying that kraft paper, that is to say packaging paper, has very different requirements with regard to tear and burst strength than, for example, cigarette papers. At the latter is less about tensile strength than about a defined air permeability, while again the most important thing is the printability of newsprint or graphic arts papers.
  • the relationship between the fiber support points FUP in the longitudinal direction of the fibers and the fiber support points FUP in the transverse direction of the thread is crucial.
  • the term "fiber support point” is understood to mean all those thread surface parts which stand out the most from the sheet formation plane of the forming wire and in this respect most likely come into contact with the fibers of the pulp.
  • the drawing figures 1 and 2 which show known forming fabrics of paper machine screens, in which, according to FIG. 1, the fiber support points have a balanced ratio in the longitudinal and transverse directions, i.e. are represented 1: 1 numerically, and according to FIG. 2 are clearly dominant in the longitudinal direction compared to the transverse direction, that is to say are represented in a larger number.
  • the object of the invention is therefore to bring about the adaptation of the surface structure of the paper to be produced to the respective application or the respective desired properties with the aid of binding means without changing the basic weave of the forming fabric in its character.
  • This object is achieved according to the invention in that at least some of the longitudinal threads and / or transverse threads of the forming fabric are assigned partner threads which run at least in one repeat parallel and thus are identical to the relevant longitudinal threads and / or transverse threads and the numerical ratio of the longitudinal fiber support points to the transverse ones Change the support points of the forming fabric.
  • Partner threads are threads that are associated with certain threads of the predetermined weave of the forming fabric, i.e., are at least partially integrated in the same way as the threads to which they are associated. These partner threads thus cause at least a part of the points at which the threads to which they are assigned to form a fiber support point virtually double this support point because they form a second point in addition to the first point, as a result of which the sheet formation surface of the threads increases accordingly .
  • the number of partner threads can be selected, it can be selected for forming fabrics that have a large difference between the existing fiber support points in the transverse and longitudinal directions of the fabric, so that the same number of fiber support points in the fabric in the two directions mentioned is installed.
  • the longitudinal fiber support points are identified by an x, the transverse ones by a circle. This marking makes it clear that the ratio of the number of longitudinal to the transverse fiber support points is balanced.
  • FIG. 2 also shows a known forming fabric in linen weave, in which, however, the longitudinal fiber support points, once again marked with x, clearly dominate over the transverse fiber support points.
  • At least some of the longitudinal threads and / or transverse threads of the forming fabric are associated with partner threads which run at least in one pattern parallel and thus are identical to the relevant longitudinal threads and / or transverse threads, whereby the numerical ratio of the longitudinal fiber support points to the transverse fiber support points of the forming fabric is changed.
  • the number of longitudinal fiber support points, identified by an x was originally greater than that of the transverse fiber support points, identified by a circle.
  • the partner threads 1 which run parallel to the transverse threads
  • every second of the forming fabric in linen weave having a partner thread 1 associated with it, which runs parallel in all adjacent repeats, that is to say the same weave the number of transverse fiber support points has been increased so that the original overweight is now balanced. Every second transverse thread of the forming fabric is therefore carried out twice in this embodiment. Nevertheless, the character of the respective original fabric is hardly changed by these partner threads. Its specific properties, such as stability, rigidity, wear behavior, drainage behavior u. Like., remain in Maintain unchanged or change due to the installation of the partner threads 1 only within tolerable limits.
  • a partner thread 2 is associated with every second transverse thread of the forming fabric, the partner threads running in the same pattern only in every second adjacent repeat and in the intermediate repeats are not involved.
  • the partner threads 2 are therefore bound 3: 1, i.e. they run over three longitudinal threads and then under one longitudinal thread, so they differ from the specified transverse threads to which they are assigned in that they are only crossed by a longitudinal thread in every second adjacent repeat , so are involved there.
  • a partner thread can be assigned not to every second thread but to each transverse thread or longitudinal thread.
