Definitions

  • the invention relates to a covering for the sheet forming part of a paper machine, e.g. a so-called sheet forming sieve.
  • the covering consists of a double-layer fabric, i.e. there are two layers of cross threads and the longitudinal threads are interwoven with each of the two layers of cross threads.
  • the transverse threads are predominantly visible both on the running side and on the paper side.
  • the longitudinal threads are bound twice per repeat in the upper layer of the cross threads.
  • the transverse threads lie over at least 80% of the longitudinal threads. The fact that the number of transverse threads on the running side is only half as large as that on the paper side is compensated for by the larger diameter of the transverse threads in the lower layer.
  • Such a sheet forming screen is known from DE-A-2,706,235 (Fig. 2F).
  • the longitudinal threads run relatively flat in spite of being bound twice into the upper layer in the interior of the fabric, and this has the consequence that the woven seam, with which the two ends of the fabric are joined together to form an endless band with a flat weave, has a relatively low strength .
  • the woven seam is quickly destroyed when cleaning with a high pressure water jet from the running side. The places where the longitudinal and warp thread ends meet within the woven seam are freely distributed within the woven seam.
  • each joint is an interruption of the warp thread, so that the transverse or weft thread of the lower layer is not held at the joint of the warp thread ends and is increasingly ground down to a width that corresponds to two weave repeats .
  • the unbound free warp thread ends are very quickly shredded and destroyed when the paper machine screen is cleaned with a high-pressure water jet.
  • a double-layered forming screen is known in which the longitudinal threads are bound twice per repeat in the upper layer of the transverse threads, but only once in the lower layer of the transverse threads.
  • This sheet forming screen has the same number of transverse threads in the upper and lower layers, so that the double integration of the longitudinal threads in the upper layer of the transverse threads results in a shortening of the transverse thread floats on the paper side. This is noticeable by a poor removal of the paper web from the sheet forming screen.
  • a similar sheet forming sieve is also known from DE-B-2,263,476, the longitudinal threads being bound two or three times in the upper layer. In the lower layer, the longitudinal threads run under two or three transverse threads and are therefore exposed to heavy wear. In DE-B-2,540,490 this is corrected in such a way that each longitudinal thread binds at most with every sixth transverse thread of the lower layer.
  • the low drainage performance and the poor sheet removal, particularly in the case of tissue paper are also disadvantageous.
  • the invention has for its object to provide a covering for the sheet forming part of a paper machine, which is characterized by an improved combination of retention, drainage performance and sheet removal.
  • this object is achieved in that the longitudinal threads per repeat are integrated twice in the lower layer and that two adjacent longitudinal threads lie together at each binding point, and thereby one longitudinal thread at one binding point together with the preceding longitudinal thread and the next tie-in point together with the following longitudinal thread and each longitudinal thread runs between two ties over at least one cross thread of the lower layer.
  • the floating length of the upper transverse threads is not shortened in the sheet forming sieve according to the invention by the multiple integration of the longitudinal threads.
  • the double inclusion of the longitudinal threads in the upper layer makes the surface of the fabric more closed, but surprisingly the permeability does not decrease, but becomes even larger. This may be due to the fact that the paper side consists of a large number of transverse threads and each transverse thread of the upper layer is tied only once per repeat by a longitudinal thread. This means that the transverse thread floatations remain highly monoplanar compared to the longitudinal thread offset.
  • the offset of the longitudinal threads becomes even smaller and that of the transverse threads always larger, ie the transverse threads protrude on the paper side and, depending on the construction of the fabric, also on the running side.
  • the sheet forming screen is then monoplanet on the paper side, and the fibrous web is carried by the cross threads (cross thread or weft carrier). If the same effect also occurs on the running side, the cross threads absorb the abrasion (cross thread or weft runner).
  • monoplanarity or over-monoplanarity cannot be achieved by heat-setting, since there the longitudinal threads are formed by the weft and therefore already lie in the tissue due to the weaving process.
  • the pronounced transverse structure of the paper side of the covering according to the invention in conjunction with the excess monoplanarity, provides good support for the paper web which is being formed and at the same time facilitates the removal of the paper web from the sheet-forming screen. This is particularly important for very thin tissue papers with low tensile strength.
  • the high permeability of the fabric is of equal importance for the production of tissue papers. At paper machine working speeds of 1500 to 1800 m / min and the high thinning of the paper pulp, large amounts of water have to be drained through the fabric within short drainage distances and within a very short time, especially in the production of tissue papers.
  • the covering according to the invention is particularly suitable for use on twin-wire paper machines. It has been shown that the above-mentioned ejection of the white water at the first deflection points is substantially reduced in the paper machine clothing according to the invention. The reason for this is not clear. In the case of coverings according to the prior art, in which each longitudinal thread per repeat is integrated only once in the lower layer, the lower half of the fabric is formed almost exclusively from free-standing transverse thread offsets, since the longitudinal threads once again lead diagonally upwards to the paper side will.
  • the paper machine clothing according to the invention is particularly suitable for the production of fine tissue papers on twin-wire paper machines.
  • the sheet forming sieve according to the invention is also suitable for writing and printing papers, since with sufficient permeability it enables extremely high transverse thread counts in the upper layer, which improves the retention of the paper stock and the marking. Because of the improved retention, this is the invention
  • Sheet forming screen can also be used for so-called "brown" paper types, ie for kraft papers, packaging papers based on waste paper and for cardboard.
  • the binding is also 7-, 8-, 14- or 18-strand based on the transverse threads of the lower layer.
  • transverse threads of the lower layers are expediently of a larger diameter.
  • the diameter of these transverse threads is chosen only so large that the longitudinal threads can still provide sufficient cranking of these transverse threads and that the longitudinal threads are thereby largely removed from abrasion. This offset takes place only when the covering is fixed, so that the fixing tension must be chosen accordingly in order to give the sheet-forming sieve the property of a transverse thread runner.
  • the covering according to the invention is expediently produced in an open weave, so that the transverse threads are then the weft threads and the longitudinal threads are the warp threads.
  • the production of a cross thread runner by circular weaving encounters additional difficulties, but is also possible, but requires looms with a very high number of shafts or a thread divider according to DE-C-3 108 189.
  • transverse threads of the upper and lower layers and the longitudinal threads are expediently plastic monofilaments, in particular polyester monofilaments.
  • the transverse threads of the lower layer and possibly also of the upper layer can partly. also consist of polyamide.
  • Fig. 1 shows schematically the course of a longitudinal thread
  • 2 shows a top view of the paper side of the covering
  • Fig. 3 in top view the running side
  • Fig. 4 shows the course of a longitudinal thread in another embodiment.
  • the embodiment has an upper layer 1 of transverse threads 3 and a lower layer 2 of transverse threads 4.
  • the number of transverse threads in the upper layer 1 is twice as high as in the lower layer 2, so that in the upper layer 1 a cross thread 3a lies above a cross thread 4 of the lower layer 2 and the next cross thread 3b in the middle over two cross threads 4 the lower layer 2 is.
  • Longitudinal threads 5 connect the upper layer 1 and the lower layer 2.
  • the weave repeat extends over sixteen transverse threads 3 of the upper layer or eight transverse threads 4 of the lower layer. Beginning at the left edge of the illustration, the longitudinal thread 5 runs over a transverse thread 3a of the upper layer 1, then under two transverse threads 3b and 3a of the upper layer 1, over a transverse thread 3b of the upper layer 1, then binds with the fifth transverse thread 4 of the lower layer 2, runs between the two layers 1, 2, binds with the eighth cross thread 4 of the lower layer 2 and finally runs diagonally upwards in order to bind again with the first cross thread 3a of the upper layer 1 in the next binding repeat.
  • Each longitudinal thread 5 thus binds within a weave repeat with a transverse thread 3a, which is above a transverse thread 4 of the lower layer 2, and with a transverse thread 3b, which lies in the middle over two transverse threads 4 of the lower layer.
  • a transverse thread 3a and 3b of the upper layer, with which the longitudinal thread 5 binds there must therefore be two, four or another even number of transverse threads, so that the condition is met that each longitudinal thread binds with a transverse thread 3a within one repeat, which lies over a transverse thread 4 of the lower layer 2, and sets with a transverse thread 3b which lies in the middle over two transverse threads 4 of the lower layer 2.
  • FIG. 2 The binding pattern of the paper side is shown in Fig. 2. It can be seen that adjacent longitudinal threads 5 are each offset by six transverse threads in the longitudinal direction and each weave repeat comprises eight longitudinal threads 5.
  • Fig. 3 shows a bottom view of the running side of the embodiment of Fig. 1 and 2.
  • two longitudinal threads 5 are together and bind together a transverse thread 4 of the lower layer 2.
  • the integration takes place at a binding point with the longitudinal thread 5 lying to the left and at the next binding point lying higher up in FIG. 3 with the longitudinal thread lying to the right.
  • the two bindings of the longitudinal thread 5 in the upper layer 1 follow one another directly, that is, without the binding of the longitudinal thread 5 in the lower layer 2 in between he follows.
  • the two inclusions of the longitudinal thread 5 in the lower layer 2 follow one another directly.
  • Fig. 4 an embodiment is shown in which the longitudinal thread 5 are alternately bound in the upper layer 1 and in the lower layer 2, so that between two ties in the upper layer 1, the longitudinal thread 5 is incorporated in the lower layer 2 . 4 shows the course of two adjacent longitudinal threads 5.
  • the fabric has the 8-strand weave shown in FIGS. 1 to 3 and is woven open.
  • the longitudinal threads 5 consist of polyester monofilament 0.15 mm in diameter and are arranged in a density of 68 threads / cm.
  • the transverse threads 3 of the upper layer 1 consist of polyester monofilament of 0.14 mm diameter and are arranged in a density of 42 threads / cm.
  • the transverse threads 4 of the lower layer 2 consist alternately of polyester monofilament and polyamide 6.6 monofilament with a diameter of 0.18 mm and are arranged in a density of 21 threads / cm.
  • the fixation is carried out at a temperature of about 200 ° C and with such a tension that the longitudinal thread 5 is shifted towards the inside of the fabric both on the paper side and on the running side, so that it is not exposed to abrasion on the running side and does not interfere with the sheet removal on the paper side.
  • the tissue lengthens by approx. 8%.
  • the offset height of the longitudinal threads 5 decreases, and the longitudinal threads shift into the interior of the fabric.
  • the transverse threads 3 and 4 are bent by the tension of the longitudinal threads 5, the width of the fabric being reduced by approximately 11%.
  • the transverse threads 3, 4 bulge outwards at the long floats and form the desired supermonoplane structure on the paper side and on the running side.
