Definitions

  • the invention relates to a fabric tape which is suitable for use in a machine producing and / or processing a fibrous web, in particular a paper, board, tissue or nonwoven machine.
  • Tissue bands of the generic type include warp threads which are interwoven with weft threads to form crosshairs.
  • Such fabric tapes may be woven and have an upper side and a lower side opposite thereto.
  • the warp threads are in the MD direction and the cross threads in the CMD direction of the machine.
  • Such originally fabricated fabric tapes are made endless at a fabric seam area, so that they can be operated in the machine as endless belts.
  • Such a fabric seam area can be provided, for example, by longitudinal threads which are woven back in the region of their warp end sections in order to form seam loops.
  • Such a fabric seam area may also be formed by, for example, warp thread end sections of warp yarns which are in each case paired in pairs and which are often interwoven with weft threads along a common weaving path with the formation of weft threads often forming part of the flat weave fabric portion.
  • the seam tensile strength, in the fabric seam areas provided by seam loops as well as the fabric seam areas provided by the seam fabric, depends on the number of weft yarns interwoven with the warp end portions in weaving or the number of weft yarns with which the gathered warp end portions share a common weaving path are interwoven. The strength of the seam increases with increasing Number of weft threads with which the Kettfadenendabitese are interwoven.
  • tissue suture region By weaving back or through the common web path, however, physical properties, such as, for example, permeability and thickness of the tissue band, are often influenced in the tissue suture region, so that these physical properties in the tissue suture region are locally different and different from the remaining part of the tissue band.
  • the object is achieved by a fabric tape suitable for use in a machine producing and / or processing a fibrous web, with warp threads are interwoven with weft threads to form crosshairs and at least some of the crosshairs contact surfaces of the warp threads and contact surfaces of the weft yarn are provided at which the warp and weft threads are materially interconnected.
  • the invention is characterized in that at least some of the warp and / or weft threads at least at the crosshairs at which they are materially interconnected, have a flattened cross-sectional shape with a greater width than height and the contact surface of the respective thread through one over the largest Part of the width of the thread extending portion of the outside of the thread is provided.

  • Fabric tapes are made by a weaving process in which the weft yarn is woven back and forth substantially perpendicular to the warp yarns. For this purpose, the weft thread is withdrawn from a spool, whereby the weft thread can rotate about its own axis. Such twisting is not a problem when the weft thread is a weft yarn having a circular cross-sectional shape. However, this can lead to growing problems, the more the cross-sectional shape of the weft thread deviates from the circular shape.
  • a particularly preferred embodiment of the invention therefore provides that at least some, in particular all of the crosshairs with weft threads materially connected warp threads have a flattened cross-sectional shape whose width to height ratio is greater than the ratio of width to height of the cross-sectional shape of at least some, in particular all of the weft threads materially connected to the warp threads.

  • warp yarns having a flattened cross-sectional shape also has the advantage that such warp yarns at a height equal to the diameter of circular warp yarns can have a larger cross-sectional area and thus higher strength, in particular tensile strength. This is especially useful when the warp threads extend in their length in the longitudinal direction of the fabric band.
  • warp threads with a flattened cross-sectional area in particular for the use of the fabric tape as a TAD sieve, make sense, since they provide a larger contact surface to the fibrous web than threads having a circular cross-sectional shape and therefore no longer need to be ground flat, for example by a grinding process.
  • the weft threads have a cross-sectional shape whose width to height ratio is smaller than the ratio of width to height of the flattened cross-sectional shape of the warp threads.
