Definitions

  • the invention relates to a method for producing a felt belt, in particular a press felt for a paper, board or Tissuemaschine.
  • Felt tapes in particular press felts for paper, board or tissue machines, generally have a basic structure providing the dimensional stability of the felt, which is needled on both sides with one or more nonwoven fabric layers.
  • Press felts can be provided either as endless belts or as seams. Formed as endless belts press felts have in comparison to press felts with seam the disadvantage that they are often difficult to install in the paper machine, as they can not be drawn as an open band in the machine.
  • press felts with nonwoven basic structures are already proposed, in which the basic structure comprises, for example, a longitudinal thread scrim.
  • the basic structure formed by a Leksfadengelege is, for example, from the US 4,495,680 known.
  • Most of the previously known L jossfadengelege comprehensive press felts are designed as endless belts.
  • the idea of the invention is first of all to produce a helically wound longitudinal thread layer and only in a subsequent step to apply a transverse reinforcement structure to the longitudinal thread layer and to connect it to the longitudinal thread layer. This creates a hose-like composite structure. Subsequently, opposing sections of the produced tubular composite structure are superimposed so that the tubular composite structure forms a flat structure whose length corresponds approximately to half the circumference of the tubular structure and which at its opposite longitudinal ends seam seams provided by the at least one helically wound longitudinal thread are formed. Then the flat structure is made endless by bringing the opposite seam loops together and joining them together. Furthermore, the mutually deposited portions of the flat structure are connected together to form a basic structure.
  • a plurality of flat structures are produced, which are joined together to form an endless belt at the seam loops. This means that the successive flat structures together form an endless belt.
  • the at least one thread is, for example, helically wound around two mutually spaced and substantially parallel rollers, the progress of the helical winding, i. the winding direction, perpendicular to the two rolls takes place.
  • the length of a winding corresponds to the circumference of the tubular composite structure.
  • the one or more longitudinal thread or longitudinal threads forming the longitudinal thread loop is or are advantageously designed as monofilament thread or as monofilament threads.
  • a preferred embodiment of the method according to the invention provides that the endless or forming of an endless belt before connecting the successive filed sections. Because the basic structure is first made endless before the successive layers or sections of the tubular composite structure are connected to one another and their relative position is thus fixed relative to one another, it is possible, for example, to correct length inequality and tension in the flat structure.
  • the flat or flat structures are tensioned in their or their longitudinal direction after endless movement. This can be done, for example, by passing the endless flat sheet or ribbon over a pair of spaced-apart and mutually parallel rolls and increasing the distance between the rolls in the longitudinal direction of the flat sheet.
  • An alternative embodiment of the invention provides that the endless making or forming of an endless belt takes place after the connection of the sections deposited on one another.
  • the invention provides that at least one carrier ply is applied to the longitudinal thread ply after the production of the longitudinal thread ply and before the application of the transverse reinforcing structure.
  • the carrier layer is applied to the Lssensfadengelege together with the transverse reinforcement structure.
  • the transverse reinforcement structure is first connected to the carrier layer before this arrangement is applied to and connected to the longitudinal thread layer. This can be done, for example, to fix the distance between successive thread windings before applying the transverse reinforcement structure.
  • the transverse reinforcement structure for example, has no direct contact with the Lticiansfadengelege, but is connected to the Lticiansfadengelege on the support layer.
  • the invention provides that the Leksfadengelege and the transverse reinforcement structure are connected to each other via the carrier layer.
  • the carrier layer is preferably arranged between the transverse reinforcement structure and the Leksfadengelege.
  • the carrier layer may be formed, for example, alone or in combination by a non-woven fabric layer or a film layer.
  • the carrier layer formed as a nonwoven fabric layer preferably comprises hot melt adhesive fibers.
  • the longitudinal thread layer to be bonded to the nonwoven layer by melting and re-solidifying the hot-melt adhesive fibers, and / or for connecting the transverse reinforcement structure to the nonwoven layer by melting and re-solidifying the hot-melt adhesive fibers.
  • the nonwoven fabric layer Before melting the hotmelt adhesive fibers of the nonwoven fabric layer or, alternatively, it is furthermore conceivable for the nonwoven fabric layer to be needled with the longitudinal yarn layer and / or with the transverse reinforcement structure.
  • the longitudinal thread layer and / or the transverse reinforcement structure are preferably at least partially embedded in the nonwoven layer. This means that the connection between the scrim and the carrier layer and / or between the transverse reinforcing structure and the carrier layer can be done by needling and / or by fusing. Alternatively or additionally, bonding is also conceivable.
  • the longitudinal thread layer and the transverse reinforcement structure are to be joined to the nonwoven layer comprising the melt adhesive fibers by melting and re-solidifying the melt adhesive fibers, it makes sense if the longitudinal thread layer, the transverse reinforcement structure and the fiber layer together are hot calendered together, for example by passing them together around a heated roller ,
  • the transverse reinforcement structure preferably comprises a transverse thread arrangement.
  • the transverse thread arrangement can be formed, for example, alone or in combination by: a woven fabric, knitted fabric, knitted fabric, leno fabric or a Querfadengelege.

  • the method is preferably carried out in such a way that, in the finished basic structure, each of the transverse reinforcement modules deposited on the longitudinal thread layer extends along the width of the longitudinal thread layer and the transverse reinforcement modules arranged one behind the other complete the length of the longitudinal thread layer.
  • the production of the basic structure is cost-effective, in particular, if the transverse reinforcement module exit web is present as a roll product and this is unwound from the roll during the lateral feed.
  • a winding method is also used, so that a carrier layer extending over the entire width of the felt belt can be produced by helically winding a part-width carrier web.
  • a preferred embodiment of the invention provides that the carrier layer is produced by winding a carrier web which extends only in part over the intended width of the felt belt in the direction of the intended width of the felt belt in a helical manner, in particular to the intended width of the felt belt ,
  • the carrier layer When helically winding the carrier web depending on the requirement, for example. Whether the carrier layer is to be formed one or more layers, facing edges of the same are placed on impact or overlapping regions.
  • the seam loops which are brought together or connected to one another are connected to one another by a pintle wire.
