Definitions

  • the invention relates to a drainage belt, in particular as a dryer for paper machines, which from a Variety of platelet-shaped flat bodies composed is used to adjust the permeability through openings have and / or gaps between them leave blank, the flat body over flexible connecting strands, that penetrate the flat bodies, among themselves are coupled so that in operation on the Longitudinal forces acting on the drainage tape act on them.
  • Such a drainage belt is DE 37 35 709 A1 remove.
  • This drainage belt provided by flat bodies, which as elongated, flat strips extending in the transverse direction are in the longitudinal direction of the drainage belt arranged one behind the other and by transverse Plug wires are coupled together. Use this the flat bodies alternate with each other, so that aligned Through channels arise in which the plug wires can be inserted.
  • the platelet-shaped flat body can be easily and quickly by injection molding or by extrusion getting produced. Let through their combination drainage tapes of almost any length and Make width. Permeability in the thickness direction can be placed in the Flat bodies themselves and / or by providing gaps between the flat bodies precisely and reproducibly the respective requirements are adjusted. Despite this The paper web finds through openings and / or gaps a large-area support, so practical there are no marks on the paper web. Also regarding the thickness of the flat body gives great freedom d. H. it can meet the respective machine requirements be adjusted. Corresponding freedom exists with the Choice of material for the flat body. Come for this Plastics, such as thermoplastics, thermosets and casting resins, in question. However, the flat bodies can also be made of elastomers or even metals. It is also conceivable that not all flat bodies of a drainage belt be made from the same material, so that different materials are provided alternately can.
  • the invention is therefore based on the object of a drainage belt of the type mentioned at the beginning that it is capable of absorbing high longitudinal tensile forces of the drainage belt is suitable.
  • connecting strands extend in the longitudinal direction of the paper machine clothing extend and with their ends in End pieces are anchored, which can be coupled together are.

Basically, should the connecting strands at least thermally and chemically be as resilient as the flat body itself.
  • Anchoring the connecting strands in the end pieces can be done in different ways, for example by welding, gluing, pressing or also by Wrap.
  • the end pieces can be designed as individual pieces be in which only a connecting strand or a few of which are anchored. But you can also use them as end strips be formed in which a plurality of connecting strands are anchored, the end strips also across the entire width of the drainage belt can extend.
