Definitions

  • the invention relates to a covering for the sheet-forming part of a paper machine, which is formed from a double-layer fabric with an upper and lower layer of transverse threads which are interwoven with longitudinal threads.
  • the transverse threads of the top layer and the longitudinal threads form bends directed towards the paper side, the highest points of which lie in one plane, the paper plane.
  • the longitudinal threads are bound twice in the upper layer of the transverse threads, and the number of transverse threads in the upper layer is twice as high as in the lower layer.
  • Such double-layered sheet-forming fabrics are known from DE-A-22 63 476, 25 40 490 and 27 06 235 and from EP-A-30 490.
  • the transverse thread density in the upper layer is also twice as high as in the lower layer.
  • the marking properties are achieved by extremely long shot floats, i.e. Cross thread floats, improved.
  • EP-A-30 490 as well as according to US-A-4 333 502, attempts are being made to achieve the same goal with long warp floats.
  • the invention has the object of providing a covering for the B latt Struktursteil to provide a paper machine having a particularly high labeling freedom.
  • this object is achieved in that first transverse threads of the upper layer having the paper plane tangent to offsets, which are supported in a Abkröpfungssattel a longitudinal thread, and in that alternately to the first transverse threads disposed second transverse threads of the upper layer has cranks b-plane of the paper tangent A, which are supported by two adjacent longitudinal threads, one of which rises from the inside of the fabric to the plane of the paper, while the other descends from the plane of the paper into the inside of the fabric.
  • a transverse thread is supported by an offset saddle of a longitudinal thread, the longitudinal thread runs under the relevant transverse thread, while it is guided over the preceding and the subsequent transverse thread. A resulting force acts on the cross thread and is directed upwards.
  • the first transverse threads of the upper layer are supported in this way.
  • the first Q are alternately arranged with the second transverse threads of the upper layer.
  • the second transverse threads are supported by adjacent, scissor-like longitudinal threads, ie one of the two longitudinal threads rises from the inside of the fabric to the plane of the paper, while the other descends from the plane of the paper into the inside of the fabric.
  • a support not only a force pointing upwards to the paper plane acts on a transverse thread, but also a torque which rotates it in the paper plane out of the transverse direction.
  • the longitudinal threads are guided directly before and after each cranking saddle over two transverse threads of the upper layer and adjacent longitudinal threads are offset in the longitudinal direction by six transverse threads of the upper layer.
  • the transverse threads of the lower layer are stronger than those of the upper layer to improve the abrasion resistance.
  • the abrasion resistance can be further improved if some of the transverse threads in the lower layer consist of a particularly abrasion-resistant material, for example polyamide.
  • the web process has not yet achieved a monoplanarity on the paper side. Only by thermofixing the fabric under longitudinal stretching is it achieved that the uppermost points of the offsets of the longitudinal threads and the transverse threads lie in one plane on the paper side, as is generally known.
  • the monoplanarity can be Open weave in general is more likely to reach than with endless weave.
  • the double-layer covering has an upper layer 1 of first transverse threads 3 and second transverse threads 4, which alternate with one another, and a lower layer 2 of transverse threads 5.
  • Longitudinal threads 6 are interwoven with the transverse threads 3, 4 of the upper layer 1 and the lower layer 2 and connect the two layers.
  • the transverse thread density in the upper layer 1 is twice as high as in the lower layer 2, and the covering is woven in such a way that the second transverse threads 4 of the upper layer 1 come to lie as precisely as possible over the transverse threads of the lower layer 2.
  • each longitudinal thread 6 is bound twice into the upper layer 1 by being looped in sequence over two transverse threads 3, 4 under a first transverse thread 3 and again over two transverse threads 4, 3.
  • the longitudinal thread 6 therefore forms a saddle, by means of which a first transverse thread 3 is supported, with essentially only an upward force acting on the transverse thread 3.
  • the longitudinal thread 6 runs over a distance of four transverse threads 3, 4 of the upper layer 1 or two transverse threads 5 of the lower layer 2 between the two layers 1, 2 and is then passed under a transverse thread 5 of the lower layer 2, so that it is also woven with the lower layer 2. It then runs again between the two layers 1, 2 until it rises again to the top within the next binding repeat.
  • adjacent longitudinal threads 6 are offset in the longitudinal direction by six transverse threads 3, 4 each of the upper layer 1. As can be seen in FIG. 1, adjacent longitudinal threads 6 therefore intersect below a second transverse thread 4 of the upper layer 1. This leads to a scissor-like support of this second transverse thread 4, by means of which the second transverse thread 4 is not only pressed upwards, but at the same time in the tissue plane is slightly rotated out of the transverse direction.
  • the bent portions 8 of the second transverse threads are not therefore parallel to the A-b cranks 7 of the first transverse threads 3 of the top sheet. 1
  • the weave of Figures 1 to 3 is a 7-strand weave, since it repeats itself after seven transverse threads 5 of the lower layer 2 and seven longitudinal threads 6.
  • a weave repeat thus comprises seven transverse threads 5 of the lower layer 2 and seven longitudinal threads 6 and fourteen transverse threads 3, 4 of the upper layer 1.
  • the first transverse threads 3 and the second transverse threads 4 can be made of the same material and have the same dimensions.
  • a softer material is preferably selected in connection with a larger diameter, so that the offsets 8 of these transverse threads 4 run at a larger angle to the transverse direction, which for the Labeling freedom can be advantageous.
  • Figures 4 to 6 show an embodiment analogous to that of Figures 1 to 3, but with an 8-strand binding.
  • Each longitudinal thread 6 in turn forms two offsets 9 in the upper layer 1, which are separated by an intermediate first transverse thread 3, which has an offset 7 extending in the transverse direction at this point.
  • the offsets 8 of the second transverse threads 4 again run at an angle to the transverse direction, since the second transverse threads 4 are supported in a scissor-like manner by adjacent longitudinal threads 6, which are offset from one another by six transverse threads.
  • each longitudinal thread 6 it is also possible to separate the two offsets 9 of each longitudinal thread 6 from one another not by a transverse thread 3, but by a total of three or five transverse threads of the upper layer 1.
  • the two different types of offsets are formed in each transverse thread of the upper layer 1 and run obliquely to one another. If the offsets 9 are separated by five transverse threads of the upper layer 1, the transverse threads float over four longitudinal threads and there is only a single type of offset, so that there is no longer any improvement with regard to the freedom of marking.
  • Figures 3 and 6 show the weave cartridges for the embodiments of Figures 1 and 2 or 4 and 5.
  • the numbers 1 to 7 of Fig. 3 and 1 to 8 of Fig. 6 at the bottom refer to the longitudinal threads, and the numbers 1 to 21 and 1 to 24 on the side edge refer to the cross threads of a repeat.
  • the transverse threads with the numbers 1, 4, 7, 10, etc. relate to the first transverse threads 3 supported by an offset saddle of a longitudinal thread, while the transverse threads with the numbers 2, 5, 8, etc. refer to the second transverse threads supported by scissor-shaped warp threads 4 concern.
  • the cross threads with the numbers 3, 6, 9, etc. relate to transverse threads 5 of the bottom layer 2.
  • the transverse threads with the numbers 2, 5, 8, 11, etc. belong to the lower layer, while the first transverse threads 3, supported by angled saddle, are designated with the numbers 1, 4, 7, etc., and the scissors-shaped, second transverse threads 4 with numbers 3, 6, 9, etc.
  • Each individual square of the Webpatrone provides a K Reuter wetting point between a longitudinal and a transverse thread is.
  • Black Filled squares thereby indicate that the longitudinal thread overlies the transverse thread, while white squares indicate that the transverse threads of the upper layer 1 via the longitudinal threads 6 run.
  • the squares with a black dot indicate that the transverse threads of the lower layer 2, viewed from the paper side, lie over the longitudinal threads 6.
  • the covering according to the invention is generally woven and heat-set in such a way that a longitudinal thread density of between 90 and 110% results.
  • a typical value for the longitudinal thread density is between 100 and 105%. However, lower values are appropriately chosen for tissue papers.
  • the papermaker's fabric as described herein can EP-A-0 are 048,962 also carried out accordingly, that only part of the longitudinal threads is included in the lower layer 2 of the transverse threads 5 6, while the remaining L ijnsfäden 16 only with the weft wires 3, 4 of upper layer 1 are woven so that they are not exposed to abrasion on the running side.
  • Such embodiments of the paper machine clothing according to the invention are shown in section in FIGS. 7 and 9.
  • the embodiment shown in FIG. 7 largely corresponds to that of FIG. 1, and the only difference is that every second longitudinal thread 16 is not woven into the lower layer 2.
  • Another ratio of the longitudinal threads 6 to the longitudinal threads 16 can also be selected.
  • the longitudinal threads 6 are bound twice in the upper layer 1 and once in the lower layer 2 within each weave repeat.
  • the longitudinal threads 16 are bound twice in the upper layer 1 within each weave repeat, but never in the lower layer 2. This results in very long transverse thread floats on the running side, namely those with 13 longitudinal threads, as shown in FIG. 8. There is no difference on the paper side compared to the embodiment of FIGS. 1 and 2.
  • FIGS. 9 and 10 show an embodiment of the paper machine clothing in which the one warp threads 6 are bound twice in the upper layer 1 and twice in the lower layer 2 within each weave repeat.
  • the other longitudinal threads 16 are bound twice in the upper layer 1 within each weave repeat, but never in the lower layer 2. This results in shorter transverse thread floats on the running side, namely those with 7 longitudinal threads, as shown in FIG. 10.
  • the paper side of this embodiment corresponds to that of FIGS. 4 and 5, since there are no differences with regard to the integration in the upper layer 1.
  • the paper machine clothing according to the invention can be designed in accordance with EP-A-0 120 337 so that the weave pattern in the two halves of the fabric separated by the longitudinal center line is mirror-symmetrical and the weave points form a V-pattern in the weave with a weave diagonal breaking in the middle of the weave.
  • the lateral running or A bdrif- th the running paper machine clothing in the paper machine is prevented.
  • Excessively long floats of the transverse threads are prevented by additional longitudinal threads 26 in the middle of the fabric, so that no substantially longer floats of the transverse threads occur at the boundary line of the two fabric halves than in the remaining fabric.
  • 11 shows a plan view of a section of such a paper machine clothing including some additional longitudinal threads 26.
  • F ig. 12 shows in longitudinal section an embodiment in which three layers of transverse threads are provided.
  • the upper layer 21 and the middle layer 22 of the transverse threads are interwoven with the longitudinal threads 6 as shown in FIG. 1 for the upper layer 1 and the lower layer 2.
  • the backsheet 23 of the transverse threads of FIG. 12 is an additional layer of transverse threads 25, which is woven with 27 of the middle layer 22 of the transverse threads 5 ssensfäden means of additional L. Overall, therefore, each longitudinal thread is only woven with the transverse threads of two successive layers.
  • the transverse threads 25 of the lower layer 23 expediently correspond in their arrangement to the transverse threads 5 of the middle layer 22.
  • Such a composite fabric is described and illustrated in detail in DE-A-32 25 599.
  • the paper side of this embodiment is as shown in FIG. 2.
