Definitions

  • press felt for a paper machine known, which comprises a layer of elastic foam material, which is connected to a support structure made of fiber material by needling.
  • the constructed of polymer material foam is closed cell.
  • a support structure for example, woven material is used with running in a machine longitudinal direction and a cross-machine direction yarns.
  • a band or press felt constructed in this way, a structure is created which counteracts the hydraulic or capillary forces, which want to pull water back onto the surface of a paper layer to be produced. In this way, a rewetting effect of the strip material to be produced can be minimized.
  • the EP 0 367 739 B1 discloses a method for coating a belt for a papermaking machine, in which process a thin layer of polymeric foam material is applied to the upper surface of a press fabric.
  • the foam material remains primarily on the surface of the tissue or may partially penetrate into the surface of the tissue.
  • the support structure is completely foamed into the foam material, that is embedded. This allows easy manufacturability, since the foam material on the one hand and the support structure on the other hand are not to be connected in additional operations with each other.
  • the foam material on the one hand and the support structure on the other hand are not to be connected in additional operations with each other.
  • the selection of the foam material the requirements arising in interaction with the web material to be produced can be optimally taken into account, while the selection of the carrying structure can take into account the mechanical loads occurring in the machine longitudinal direction and in the cross machine direction.
  • the foam material used is preferably open-celled.
  • thermoplastic polymer material preferably polyurethane material
  • the foam material may alternatively or additionally comprise thermosetting polymeric material, preferably melamine-formaldehyde.
  • the foam material can be made with the support structure foamed therein in a film extrusion process.
  • Fig. 1 shows a band constructed according to the invention in section.
  • band 10 which can be used for example in a press section of a machine for the production of paper or cardboard, comprises a support structure 12.
  • this is designed as a fabric or scrim with in a tape longitudinal direction running longitudinal threads 14 and extending in a transverse direction of the tape transverse threads 16.
  • the tape longitudinal direction of the machine direction and the tape transverse direction of the machine transverse direction correspond.
  • the support structure 12 is passed through an extrusion head in a film extrusion process and thereby foamed with open-cell foam material 18.
  • the foam material 18 is the support structure completely embedding provided on this and kept very stable.
  • the surfaces formed on the foam material 18 may form, for example, a strip material contact surface 20 and a machine contact surface 22.
  • the foam material 18 may, for example, thermoplastic polymer material, such as. As polyurethane material, and has due to its open-cell structure on an excellent water laxative property. By adjusting the size of the cells present in the foam material 18, the selection of the foam material per se and its dimensions, it becomes possible to optimally take into account the requirements in the area of a press section with regard to the dehumidifying properties, with regard to the abrasion properties and also the pressure-elastic properties. The mechanical stability in the longitudinal and transverse directions is ensured by the support structure 12. This can, as already mentioned, for example, be designed as a clutch. Of course, differently structured support structures, such as a fabric, a felt or nonwoven material or a net-like material can be used.
  • a plurality of layers of foam material which layers may differ in their structural or physical properties.
  • a layer of nonwoven or felt material on at least one side in order to connect, for example by needling, to the underlying foam material layer. This also makes it possible to adapt the properties of such a strip 10 to the requirements occurring in a paper machine.
