Definitions

  • the invention relates to a double fabric as a screen fabric for the wet end of a paper machine according to the preamble of claim 1.
  • sieve fabrics are known for stability, uniformity of water permeability, surface smoothness, number of stitches / cm and the like. The like. Made extraordinarily high demands.
  • the highest possible number of wearing points on the paper side of the fabric is also sought, and the highest possible wear volume on the running side of the fabric, because the surface quality of the paper to be produced u. a. also depends on the number of wearing points and the lifespan of the fabric on the wear volume. The greater the volume of wear, the longer the sieve service life.
  • US Pat. No. 3,127,308 proposes a fine upper fabric in a single weave (linen weave) to combine with a lower fabric in a three-twill weave so that the longitudinal threads of the lower fabric also cross individual transverse threads of the fine, simple upper fabric at certain points.
  • Such fabrics are called double or multiple fabrics with a connection in the technical language.
  • the production of suitable double fabrics of this type as forming fabrics has encountered difficulties, however, because the connection of the thick longitudinal threads of the lower fabric in the fine upper fabric causes such severe disruptions that faultless paper production has not been possible.
  • a double-layer screen fabric is known, which is shown in the attached drawing figure 1 and in which only a part of the longitudinal threads I, II, and preferably every second longitudinal thread II not only in the upper layer III, but also integrates into the lower layer IV of the cross threads. Since each longitudinal thread I and II is involved in the binding of the surface, i.e. the paper side of the sieve, in these sieve fabrics, the longitudinal threads II, which bind in both transverse thread layers, have to be woven from a separate warp thread roller because of their greater length.
  • the object of the invention is therefore to combine the advantages of the double-layer fabrics, which are provided with only one longitudinal thread system, and the advantages of multiple fabrics, which have at least two longitudinal thread systems, without having to take over the disadvantages shown.
  • the two sets of longitudinal threads or the three sets of longitudinal threads with the upper layer of transverse threads form a repeating weaving pattern in which at least some of the upper transverse threads are traversed by at least three successive longitudinal threads and then crossed by at least three successive longitudinal threads at least two of the last at least three successive longitudinal threads if two sets of longitudinal threads are used, at least two belong to the first set and one to the second set and if three sets of longitudinal threads are used, at least two belong to the first set and one to the second set of longitudinal threads and in the case of the use of two as well as three sets of longitudinal threads, this last-mentioned longitudinal thread of the second set only crosses an upper transverse thread within the weaving pattern (repeat), while the longitudinal threads of the first set do at least ns cross two consecutive upper cross threads once within the weaving pattern.
  • This construction ensures that the thickness of the overall fabric, that of the known double fabrics is often more than 50% larger than in double-layer fabrics, is significantly reduced so that it corresponds to the thickness of comparable double-layer fabrics.
  • the clear separation and spacing of the lower and upper fabric layer as an inevitable consequence of the use of separate binding threads is eliminated in the double fabric according to the invention, which also avoids the disadvantages of too high a fabric thickness, namely the dragging of water as well as strong relative movements in the fabric body due to an excessively large water storage volume when passing through the roller system of the wet end due to constant bending alternating stresses.
  • the double fabric as a screen fabric for the wet end of a paper machine for dewatering and forming a paper web consists of three sets of longitudinal threads and at least one upper and one lower layer of transverse threads, the first set of longitudinal threads only with the upper layer of transverse threads, the second set Longitudinal threads with two layers of transverse threads and the third set of longitudinal threads only woven with the lower layer of transverse threads, the solution to the above object is achieved in that the three sets of longitudinal threads with the upper layer of transverse threads form a repeating weaving pattern in which at least one part the upper transverse threads are traversed by at least three successive longitudinal threads and then crossed by at least three successive longitudinal threads, at least two of the latter longitudinal threads belonging to the first set and one to the second set of longitudinal threads and this longitudinal thread of the second set being only one upper thread n Cross thread crosses within the weave pattern (repeat), while the longitudinal threads of the first set cross at least once within the weave pattern two successive upper cross
  • first set of longitudinal threads with the upper layer of transverse threads form a weaving pattern in which at least some of the upper transverse threads alternately pass underneath and across the longitudinal threads of the first set in pairs.
  • the last-mentioned embodiment can be further developed in that in the weaving pattern another part of the upper transverse threads alternately passes underneath and crosses the longitudinal threads of the first set, or in that those upper transverse threads which alternately pass under and cross the longitudinal threads of the first set in order one or two longitudinal threads of the first set are offset with respect to each other.
  • Another advantageous fabric construction variant follows the one in which in the weave pattern another part of the upper transverse threads alternately passes underneath and crosses the longitudinal threads of the first set, in that those upper transverse threads which alternately pass underneath and separately the longitudinal threads of the first set cross, in each case one longitudinal thread of the first set are offset with respect to one another.
  • the lower transverse threads can span three successive longitudinal threads of the second set and all the longitudinal threads of the first set downwards, as seen from the underside of the fabric.
  • two successive ones one belonging to the second set of longitudinal threads and the other to the third set of longitudinal threads, can be bound in such a way that they are not bound in the same transverse threads of the lower layer.
  • the fabric can be designed according to a further embodiment so that the longitudinal threads of the second set at the points where they cross an upper transverse thread, a plane that lies below the plane which is affected by the longitudinal threads of the first set at those points at which these longitudinal threads of the first set cross the upper transverse threads.
  • the two planes can be spaced apart by at least 15% of the largest diameter of the longitudinal threads of the first or second set.
  • the double fabric or screen fabric shown in FIG. 1 is known and was mentioned at the beginning. It is therefore not explained in more detail here.
  • the screen fabric shown in section in FIG. 2 is woven with 8 strands and is shown in FIG. 4 in a top view of the paper side and in FIG. 5 in a top view of the running side.
  • This screen fabric has a total of approximately 75 longitudinal threads of the first set 10 to 13; 10 'to 13', and the second set 20 to 23; 20 'to 23', per cm of polyester with a diameter of 0.15 mm.
  • Its upper cross threads 40 to 47 are also made of polyester and have a diameter of 0.13 to 0.15 mm, while the diameter of the lower cross threads 50 to 53 is 0.20 mm or 0.22 mm and every second cross thread is made of polyamide can.
  • the distance between the two planes is essentially generated by the type of weave and not by the formation of so-called "wells", as they occur in known double fabrics.
  • this screen fabric When ground, this screen fabric has a thickness of approx. 0.63 to 0.56 mm and is therefore not significantly thicker than the known double-layer fabrics of corresponding fineness.
  • the change from longer to shorter floats of the transverse threads 40 to 47 on the paper side results in a low-marking surface which enables very favorable fiber placement and fiber distribution of the paper stock.
  • this screen fabric Despite the relatively high longitudinal thread density and the relatively high number of transverse threads on the paper side of approx. 34 / cm, this screen fabric still has a good air permeability of approx. 2,200 l / m2. s.
  • a construction is realized which is characterized in that the two sets of longitudinal threads 10 to 13 and 20 to 23 designated with 1 and 2 with the upper layer of transverse threads 40 to 47 form a repeating weave pattern in which at least a portion of the upper transverse threads 41, 43, 45, 47 are traversed by five successive longitudinal threads and then crossed by three successive longitudinal threads, two of the last three successive longitudinal threads being the first set 1 and one the belong to the second set 2 and the latter longitudinal thread of the second set only crosses an upper transverse thread within the weaving pattern or repeat, while the longitudinal threads of the first set twice within cross two consecutive upper cross threads of the weaving pattern.
  • FIG. 4 show how and where the longitudinal threads 20 to 23 of the second set 2 are incorporated with reference to FIG. 5.
  • those upper transverse threads 41, 43, 45, 47 which alternately pass underneath and cross the longitudinal threads of the first set 1 in pairs, are offset with respect to one another by one longitudinal thread of the first set 1.
  • those upper transverse threads 40, 42, 44, 46 which alternately pass underneath and cross the longitudinal threads of the first set 1 in order to offset one longitudinal thread of the first set 1 in relation to one another.
  • This embodiment is characterized in that not only those upper transverse threads 41, 43, 45, 47, which cross the longitudinal threads of the first set 1 alternately under and over, are offset by one longitudinal thread of the first set 1 in relation to each other, but that the lower transverse threads 60 to 67 span seven consecutive longitudinal threads of the second longitudinal thread set 2 and all the longitudinal threads of the first set 1 downwards, as seen from the underside of the fabric.
  • the lower or running transverse threads 60 to 67 form very long floats, which further increases the available wear volume.
  • a further embodiment of the screen fabric forming double fabric according to the invention is shown, in which a third set of longitudinal threads 3, consisting of the longitudinal threads 30 to 33, is used, the transverse threads 50 'to 53 only with the lower layer 'Is woven.
  • the three sets of longitudinal threads 1, 2, 3 with the upper layer of transverse threads 40 'to 47' also form a repeating weave pattern, in which at least some of the upper transverse threads 41 ', 43', 45 ', 47' are traversed by five successive longitudinal threads and then crossed by three successive longitudinal threads, two of the latter longitudinal threads belonging to the first set 1 and one to the second longitudinal thread set 2, and the longitudinal thread of the second set crossing only one upper transverse thread within the weaving pattern or repeat, while the longitudinal threads of the first Set twice within the weaving pattern or repeat Cross two successive upper cross threads.
  • Fig. 7 shows a further top view of the upper or paper-side layer of a top view of Fig. 4 comparable embodiment of the screen fabric, in which those upper transverse threads 41 ', 43', 45 ', 47', which alternate the longitudinal threads of the first set 1 Cross underneath and in pairs, in each case two longitudinal threads of the first set 1 are offset with respect to one another, and those upper transverse threads 40, 42, 44, 46; 40 ', 42', 44 ', 46', which alternately pass underneath and cross the longitudinal threads of the first set 1, each offset by a longitudinal thread of the first set 1 with respect to one another.
  • FIG. 8 shows the lower or running layer of the fabric belonging to the upper or paper-side layer of the screen fabric shown in FIG. 7, the circles denoted by d and e in the last two drawing figures indicating the position of the two layers relative to one another.
