Definitions

  • the present invention relates to a paper machine clothing according to the preamble of claim 1.
  • These screens have a paper-side weave structure which is connected by binder threads to a machine-side weave structure.
  • the binding threads are interwoven with the paper-side weave structure to form tie-up points and machine-side weave structure to form tie-off points.
  • the conventionally shot-bound, three-ply fabric with a separate binding thread system can no longer meet the requirements with respect to monoplanity of the surface and consequently the requirements for the marking behavior.
  • the pure binding threads have been given an additional 'task' by using them as part of the paper-side weave structure, ie the binding threads continued the weave structure formed by the warp and weft threads.
  • the binding threads to the binding effect also has a fiber supporting effect.
  • Such forming fabrics are referred to as SSB screens, where SSB stands for structurally-bonded or "sheet support binder". The marking tendency on the paper side can be considerably reduced by this measure.
  • the known forming fabrics continue to have too high marking tendencies.
  • the high marking tendencies are caused, inter alia, by the tying and binding points of the binding threads on the paper-side and the machine-side weave structure by the planarity and permeability (permeability) of the sieve and thus the dewatering behavior of the pulp suspension is changed at these locations.
  • a screen for the production of tissue paper which has an upper and a lower fabric layer, wherein the two fabric layers are connected by binding threads that form constrictions through which significantly less water can flow through than adjacent areas of the screen.
  • the invention is achieved by a paper machine clothing with the features of claim 1.
  • the invention is based on the recognition that a mark caused by the setting or tying points becomes clearly visible to an observer, especially when the tying or tying points in the tying point or setting point repeat unit are arranged completely regularly with respect to one another.
  • a papermachine fabric is proposed with a paper-side and a machine-side weave structure and binding threads, which are interwoven to form tying points with the paper side and formation of bonding points with the machine-side weave structure, wherein the arrangement of the tethering points or the Abbindehav by juxtaposition of several smallest Anbindetician- or Abbindeticianwiederholriaden can be described, and wherein in each tying point and / or Abbindeddlingwiederholappel at least one of the setting or tethering points in relation to the other setting or tethering points is arranged irregularly, the tying each are arranged as a pair of binder yarns, whereby, for example, each binder thread pair on the paper side weaves the path of a non-binding weft or warp and wherein by weaving the binding threads with the paper-side warp or paper-side wefts a webmaster is formed by the paper side warp and Weft threads is continued.
  • the paper-side woven structure of the paper machine clothing is a plain weave and the papermaking fabric itself is a forming fabric for the production of graphic papers.
  • Tying points and bonding points are defined as follows: At a tying point, a binding thread running in the CD direction weaves over a paper-side MD thread, at a setting point the binding thread weaves under a machine-side MD thread. Between consecutive tying and setting points no paper-side MD thread is arranged over which the binder thread weaves. Between the successive tying and setting points, no machine-side MD thread is arranged below which the binder thread weaves.
  • a binding yarn running in the MD direction at a tying point, the binding yarn running in the MD direction weaves over a paper-side CD yarn, at a setting point the binder yarn weaves under a machine-side CD yarn. Between each successive tying and binding points no paper-side CD thread is arranged over which weaves the binder thread. Between successive tying and bonding points, no machine-side CD thread is arranged underneath which weaves the binder thread.
  • An irregular arrangement is to be understood as meaning that at least one of the bonding points or attachment points breaks through the pattern formed by the remaining bonding points or attachment points or does not continue this pattern. That is, for example, all setting point are arranged along one of a plurality of mutually parallel straight lines, wherein a setting point is not arranged on one of the straight lines.
  • the setting or attachment points are arranged regularly relative to one another, it is, for example, possible to arrange these along mutually parallel straight lines.
  • a possibility of irregular arrangement can be caused by some of the setting and / or Anbinde08 are arranged in the Abbinderios- or Anbindeddlingwiederholü such that they can be connected only by at least one straight line, which is not parallel to another Abbinde- or Connecting points interconnecting lines runs.
  • a particularly preferred embodiment of the invention therefore provides that the irregular arrangement is caused by some of the tethering and / or Abbinde08 are arranged in the Abbinderios- or Anbindeticianholussi so that these tethering and / or Abbinde08 not by a straight line in a first Abbindetician- or Anbindeticianwiederholussi connect, which can be continued by connecting tying or Abbindeticianen in one of the first Abbindetician- or Anbindeticianwiederholussi adjacent second Abbindetician- or Anbindeticianholriad.
  • a particularly preferred embodiment of the invention provides that the irregular arrangement is caused by some of the attachment points and / or Abbinde08 are arranged in the Abbinderioshuiwiederholussi so such that these tethering and / or Abbinde08 not through a line in a first Abbindetician- or Anbindeticianwiederholussi connect with each other, which runs parallel to a straight line, the tying or Abbinde08 in one of the first Abbindetician- or Anbindeticianwiederholussi adjacent second Abbindetician- or Anbindeticianwiederholhow interconnected.
  • At least one straight line can not be “continued” by a straight line parallel thereto in an adjoining tie point or tying repeat unit, but rather that the straight line in continuation of the tying point repeat unit is discontinuous, e.g. broken, which greatly reduces the visibility of the mark.
  • Another possibility for influencing the regularity of the setting or tying points is that at least some setting or tying points arranged along a straight line are spaced apart from one another along the straight line.
  • a preferred embodiment of the invention provides that up to 20%, preferably up to 30%, particularly preferably up to 50% and very particularly preferably up to 70% of the setting or tying points in the setting point or tying repeat unit not a regular Patterns are arranged following.
  • the paper machine clothing can be described by stringing together a plurality of smallest repeat units, wherein the smallest repeat unit of the papermachine clothing is the least common multiple of the smallest repeat unit of the paper side weave structure, the smallest repeat unit of the machine side weave structure, the tie point and the tether repeat unit.
  • the possibility of variation in influencing the irregular arrangement of the setting or tying points can be increased considerably by increasing the number of warp threads per smallest repeat unit.
  • a particularly preferred embodiment of the invention provides that the smallest repeat unit of the paper machine clothing is formed by 24 or 26 or 28 or 30 or 40 or more warp threads.
  • the Abbinderios- or Anbindeticianholhow is formed by a maximum of 5 or 7 warp threads.
  • binding threads run in the warp and / or weft direction.
  • the paper-side weave pattern is formed only by weaving paper-side warp or weft threads with the binding threads.
  • the paper machine clothing is a forming fabric.
  • FIG. 1 shows the distribution of setting points 1 of the binding threads of a Formieriebs 2 with a six Kettfäden 1K to 6K and twelve running in the weft binding threads 1 B to 12B formed Abbindeddlingwiederholriad.
  • the Abbindeix 1 are in the representation of FIG. 1 represented by black squares.
  • the Abbindelie 1 are regularly arranged to each other, which can be connected by a plurality of mutually parallel lines 3 together.
  • the Abbindework 1 in the Formierieb 2 of FIG. 1 are arranged such that the straight lines 3 connecting the bonding points 1 can be continued by a setting point repeat unit 4 in the adjacent repeat units 5, 5 ', 5 " Tying to a change in the pore structure, which leads to quality-reducing markings in the paper as a result, especially in the graphic paper area.
  • FIG. 2 shows a distribution of Abbindeterrorism on the machine side 7 of a forming fabric according to the invention 8.
  • a smallest Abbindeddlingwiederholhow the forming fabric 8 shown is formed by 30 warp yarns 1 K to 30 K and 15 in the weft direction binding threads 1 B to 15B.
  • four adjoining smallest Abbindeticianwiederholhow 9 to 12 are shown.
  • Each Abbindeticianwiederholhowderholhow 9 to 12 has in the right area a number of mutually regularly arranged setting points 13, which are connected to each other via parallel lines 14.1 to 14.4. Some of these lines can also be continued in the adjacent repeat units. Thus, for example, the straight 14.1 of the repeat unit 9 is continued by the straight line 14.2 of the repeat unit 10. Or else the straight 14.2 from the repeat unit 9 is continued by the line 14.3 of the repeat unit 10.
  • the left area of each smallest Abbindeticianwiederholhowderholhow many of mutually regularly arranged setting points 15 are provided, but which are arranged irregularly with respect to the Abindeddlingen 13, i. do not continue the pattern formed by the bonding points 13. Accordingly, in each Abbindeddlingwiederholhow 9 to 12, the binding points 15 with respect to the binding points 13 are arranged irregularly.
  • the irregular arrangement is caused by some of the Abbindeimi 15, for example, in the Abbinderioswiederholhow 9 are arranged such that the bonding points 15 can not be connected by a straight line, which by connecting bonding points 13 or 15 in a of the tying point repeat unit 9 to continue adjoining tying point repeat unit 10 or 11 or 12.
  • FIG. 3 shows a further embodiment of the invention in the form of a Formieriebes 17 with almost free distribution of its Abbindeach 18 and 19.
  • Each Abbindeticianwiederholhow 21 to 24 is formed by 30 warp yarns 1 K to 30 K and 15 weft extending binding threads 1B to 15B. Only the binding points 18 are arranged to each other such that they can be connected to each other by parallel lines 20.1 and 20.2. Furthermore, it can be seen that the grades 20.2 of the Abbindeddlingwiederholhow 21 continues in the line 20.1 of the repeat unit 22.
  • FIG. 4 The arrangement of the bonding points 28 to 32 is described by one of the Abbindeticianwiederholticianen 24 to 27, each Abbindeticianwiederholtician 24 to 27 by five warp yarns 1 K to 5 K and five running in the weft binding threads 1 B to 5 B is formed.
