Definitions

  • the present invention relates to a belt for a machine for producing sheet material, such as e.g. Paper or board, and a method for producing such a tape.
  • bands are used in different sections, which are permeable to the removal of moisture from the web material to be produced for air or steam.
  • Such bands to be used for example, in press sections or dry sections are often provided to provide this required permeability as fabric tapes with longitudinal threads running in a tape longitudinal direction and transverse threads running in a tape transverse direction, wherein generally the tape longitudinal direction also corresponds to the direction of movement of the tape.
  • a strip for a machine for producing web material comprising at least one fabric layer with longitudinal threads extending substantially in one strip longitudinal direction and transverse threads extending substantially in a strip transverse direction, wherein, to provide an endless configuration of the band, end portions of the longitudinal threads are interwoven with connecting transverse threads, wherein at yarn ends of at least a portion of the Cross-linked interconnecting threads longitudinal cross-sectional extensions are provided.
  • the cross-sectional enlargements form an integral part of the longitudinal threads.
  • additional materials such as e.g. Glue or the like can be dispensed with.
  • additional material such as e.g. Adhesives
  • At least a part of the cross-sectional extensions may be formed by knotting the thread ends.
  • At least part of the cross-sectional enlargements be formed by deformation of the thread ends.
  • at least a part of the longitudinal threads provided with cross-sectional widening is constructed of thermoplastic material and that the cross-sectional widenings are formed by hot deformation.
  • At least part of the cross-sectional widenings is formed by attaching clamping elements to the thread ends. This variant is particularly advantageous if, due to the dimensioning or the material the longitudinal threads knotting the thread ends or the deformation of the thread ends, for example by thermal action, is not possible.
  • the cross-sectional widenings at the thread ends be dimensioned such that they are larger than the fabric interspaces generated in the region of such thread ends by the threads surrounding them.
  • such strips in various areas of machines for the production of web material, that is, for example, paper machines.
  • a band may be provided for use in a press section. It is also possible to provide such a band for use in a dry section.
  • a belt for a machine for making web material is generally designated 10.
  • This band which can be used, for example, in a press section or a dry section, comprises a band body 12, which in the example shown is constructed with a fabric layer 14.
  • This fabric layer 14 comprises longitudinal yarns 16 running in a band longitudinal direction and transverse yarns 18, ie substantially transverse in a ribbon transverse direction.
  • the longitudinal yarns 16 can advantageously be warp yarns, while the transverse yarns are weft yarns. In this way, it becomes possible to weave this with almost any length for a given width of such a band 10.
  • the band body 12 is woven during the weaving process so that the longitudinal threads 16, ie, for example warp threads, have interwoven end regions at their two end regions 20, 22, ie, with transverse threads 18, for example weft threads 24 and 26 are provided.
  • the two recognizable end regions 24 and 26 at the ends 20, 22 of the band body 14 are respective end regions of the same longitudinal thread 16, which of course does not necessarily have to be the case.
  • These end portions 24, 26 of the or each longitudinal thread 16 are then interwoven to form a connection zone V with connecting transverse threads VQ.
  • the connection zone V comprises the connecting transverse threads 1, 2, 3, 4 and 5.
  • connection zone V a fabric structure, preferably the fabric structure, is obtained by the end regions 24 and 26 of the longitudinal threads 16 and the connecting transverse threads VQ , which is present in the remaining band body 12 corresponds, so that over the entire length of the band 10 now provided in endless configuration uniform surface properties are present.
  • cross-sectional widenings are formed in the band 10 according to the invention in the area of these thread ends 28 and 30 in the manner described below. It is first after the generation of the connection zone V by the use of the thread end 28 in Fig. 1 recognizable cutting tools 32 ensured that, as already apparent from the thread end 30, they project beyond the fabric layer 14 only to a predetermined extent. This predetermined extent may of course also be dependent on the thickness of the longitudinal threads 16 in the range of 3 to 5 mm.
  • the thread ends 28 and 30 After at least in those areas in which cross-sectional enlargements are to be formed, for example, the edge region of such a belt 10, the thread ends 28 and 30 have been shortened to this predetermined length or have already been provided in the connection process with such length, then become These thread ends 28 and 30, the cross-sectional extensions provided.
  • longitudinal threads 16 with thermoplastic construction material, for example polyethylene, this can be achieved by providing a by in Fig. 2 indicated tool 24, for example one of the tip of a soldering iron, on the Thread ends 28 and 30 is acted upon.
  • a by in Fig. 2 indicated tool 24 for example one of the tip of a soldering iron
  • the cross-sectional widenings 36, 38 will form with appropriate pressure loading by the tool 34 so that they conform to the shape of the surrounding threads .
  • the cross-sectional enlargements will have a dimension which is greater than a respective tissue interspace in which a longitudinal thread 16 having such a cross-sectional widening 36 or 38 extends between the further longitudinal threads 16 or transverse threads 18 surrounding it. In this way it can be reliably ensured that thus treated thread ends 28 and 30 can no longer slip out of the fabric structure.
  • cross-sectional enlargements are not generated by thermal treatment, but by knotting, so forming nodes at the thread ends.
  • the cross-sectional enlargements thus form an integral part of the longitudinal threads 16 themselves, since they are also made of their structural material, albeit by mechanical treatment.
