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 within each weave repeat.
  • first transverse threads of the upper layer tangent to the paper plane are supported in an offsetting saddle of the longitudinal threads
  • the offsets of second transverse threads of the upper layer tangent to the paper plane are supported by two adjacent longitudinal threads, one of which rises from the inside of the fabric to the paper plane, while the other of descends into the interior of the tissue.
  • transverse threads are arranged such that two second transverse threads and then two first transverse threads follow each of two first transverse threads.
  • the arrangement of the transverse threads in pairs emphasizes the paper markings caused by the individual types of transverse thread, so that the paper quality suffers.
  • the invention has for its object to provide a covering for the sheet forming part of a paper machine, which has a particularly high freedom of marking.
  • this object is achieved in that the first transverse threads and the second transverse threads are arranged alternately.
  • a transverse thread is supported by an offset saddle of a longitudinal thread, the longitudinal thread runs under the relevant transverse thread, while being 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 transverse threads are arranged alternately with second transverse threads of the upper layer.
  • the second transverse threads are supported by adjacent, scissor-like longitudinal threads, i. that is, 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.
  • 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 longitudinal and transverse threads are expediently made of plastic monofilaments, in particular polyester monofilament.
  • 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 by a part of the transverse threads of the lower layer made of a particularly abrasion-resistant material, e.g. B. 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. Monoplanarity is generally more likely to be achieved with an open weave than with an 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 also in the tissue plane is slightly rotated out of the transverse direction.
  • the offsets 8 of the second transverse threads are therefore not parallel to the offsets 7 of the first transverse threads 3 of the upper layer 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 of the same material and have the same dimensions.
  • a softer material is preferably expediently 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 can be advantageous for the freedom from marking.
  • 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 there is also the option of. not to separate the two offsets 9 of each longitudinal thread 6 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. refer 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., the warp threads guided by scissors supported second cross threads 4 concern.
  • the transverse threads with the numbers 3, 6, 9 etc. relate to transverse threads 5 of the lower layer 2.
  • the transverse threads with the numbers 2, 5, 8, 11 etc. belong to the lower layer, while those supported by angled saddle .
  • First transverse threads 3 with the numbers 1, 4, 7, etc. are referred to and relate to the scissors-shaped, second transverse threads 4 with the numbers 3, 6, 9, etc.
  • Each individual square of the weaving cartridge represents a crossing point between a longitudinal thread and a transverse thread.
  • Squares filled in black indicate that the longitudinal thread lies above the transverse thread, while white squares indicate that the transverse threads of the upper layer 1 run over the longitudinal threads 6.
  • 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 paper machine clothing described here can also be carried out in accordance with EP-A-Q048 962 in such a way that only part of the longitudinal threads 6 is bound into the lower layer 2 of the transverse threads 5, while the remaining longitudinal threads 16 are only connected with the weft wires 3, 4 of the upper layer 1 are woven so that they are not exposed to abrasion on the barrel 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 each weave repeat in the upper layer 1, 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 into 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. This prevents lateral running or drifting of the running paper machine clothing in the paper machine. 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 rest of the fabric. 11 shows a plan view of a section of such a paper machine clothing including some additional longitudinal threads 26.
  • Fig. 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 lower layer 23 of the transverse threads of FIG. 12 is an additional layer of transverse threads 25, which is interwoven with the middle layer 22 of the transverse threads 5 by means of additional longitudinal threads 27. 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.
  • a covering with a 7-shaft binding according to FIGS. 1 to 3 is produced in an open weave.
  • the longitudinal threads consist of polyester monofilament with a high modulus of elasticity and a diameter of 0.15 mm. After heat setting, the longitudinal thread density is 71 wires / cm.
  • the first transverse threads 3 of the top layer 1 are polyester monofilaments with a diameter of 0.17 mm and have a medium modulus of elasticity (elongation 19% under a load of 27 cN / tex).
  • the second cross threads 4 are polyester monofilaments of 0.185 mm in diameter and have a relatively low modulus of elasticity (elongation 23.4% at a load of 27 cN / tex). After heat setting, the cross thread density in the top layer 1 is a total of 36 / cm.
  • the transverse threads 5 of the lower layer 2, which form the running side, are alternately particularly soft polyester monofilaments (elongation 23.4% with a load of 27 cN / tex) of 0.20 mm and soft polyamide 6 monofilaments of 0. 21 mm in diameter, and after heat setting, the cross thread density in the lower layer 2 is a total of 18 / cm.
  • the fabric is heat-set in such a way that the bends 7 and 8 of the first transverse threads 3 and the second transverse threads 4 and the bends 9 of the longitudinal threads 6 lie in one plane on the paper side, so that the fabric is monoplan.
  • care was taken to ensure that the first transverse threads 3 of the upper layer 1 lie exactly above the transverse threads 5 of the lower layer 2.
  • a covering with an 8-strand binding according to FIGS. 4 to 6 is produced in an open weave and, after being fixed, is made endless with a woven seam.
  • the fabric is woven with a longitudinal thread count of 54 / cm. During heat setting, the number of longitudinal threads increases to 60 / cm due to the transverse contraction of the fabric.
  • the longitudinal threads consist of polyester monofilament with a diameter of 0.17 mm and a longitudinally stable quality with a high modulus of elasticity.
  • the cross threads 3 of the upper layer consist of polyester monofilament of 0.17 mm diameter with a relatively hard weft quality (type Trevira 902 with a relatively high modulus of elasticity for weft wires corresponding to an elongation of 8.5% under a load of 27 cN / tex).
  • the second weft threads 4 of the upper layer 1 are also polyester monofilaments, but of the softer type Trevira 900 corresponding to an elongation of 23.4% at 27 cN / tex and a diameter of 0.20 mm.
  • This fabric is woven with a total cross thread density of 35 / cm, whereby the number of cross threads is reduced to 32 / cm in the top layer 1 and to 16 / cm in the bottom layer 2 by heat setting.
  • the transverse threads 5 of the lower layer 2 are alternately polyester monofilaments with a diameter of 0.22 mm of the soft type Trevira 900 corresponding to an elongation of 23.5% at 27 cN / tex and polyamide monofilaments of the type PA 6.6 with a diameter of 0, 24 mm.
  • the fabric is fixed at 195 'C, whereby a maximum longitudinal tension of 95 N / cm is reached.
  • the longitudinal and transverse threads are bent:
  • the longitudinal threads (warp) originally lying on the outside of the woven screen cloth stretch under the influence of the fixing tension and heat and are embedded in the interior of the fabric as a result of this bending.
  • the longitudinal thread floats and the floats of the first transverse threads 3 and the second transverse threads 4 directed towards the paper side all lie in one plane.
  • the longitudinal thread 6 forces the transverse threads 5 to bend strongly, so that in the finished covering alone, the floats of the transverse threads 5 the outside, ie. H. form the running side of the fabric in the lower layer 2.
