Definitions

  • the invention relates to a seamable press felt for a machine for producing and / or treating a fibrous web, such as a paper, board or tissue web, and a method for the production thereof.
  • Press felts usually consist of a tensile load-bearing support structure, which also provides substantially the dimensional stability of the press felt.
  • the carrier structures of today's seamable press felts are often woven round, with the machine direction yarn being woven back to form seam loops.
  • the disadvantage of woven structures is that the round weaving process is time-consuming and costly. Further, since the warp yarn forms the cross-machine direction yarns and the weft yarns the machine direction yarns, the length of such carrier structures is limited to the width of weaving machines used in weaving.
  • the US 3,948,722 shows a dimensionally stable warp knit for a papermachine fabric, which has a plurality of intersecting yarns of a thickness of at least 500 denier and other inserted therebetween threads and / or resin for stabilization.
  • the object is achieved by a press felt for a machine for producing and / or treating a fibrous web, in particular paper, board or tissue web.
  • the press felt has a carrier structure substantially affecting the dimensional stability of the felt.
  • the support structure comprises a flat fabric produced, which is formed from longitudinal yarns and these crossing transverse yarns and sewing threads, which connect the longitudinal and the transverse yarns at the intersection points.
  • the textile fabric of the press felt according to the invention is longer than the length of the support structure and deposited in sections on itself, that the support structure is formed by a plurality of extending over the entire length of the support structure layers of textile fabric.
  • the layers arranged on one another are connected to each other at least in sections.
  • edges are formed, which extend transversely to the longitudinal direction of the support structure and define a one and another transverse end of the support structure.
  • the longitudinal yarns are curved to form seam loops at the two transverse ends of the support structure.
  • the support structure is seamable in a paper machine by guiding the two transverse ends of the support structure to make the support structure endless, and engaging the seam loops to form a connecting channel extending transversely of the support structure.
  • a pintle wire is passed through the connection channel of the support structure.
  • the transverse yarns are spaced apart from each other, wherein the distance between adjacent transverse yarns corresponds at least to the diameter of the transverse yarns.
  • the layers of the textile fabric are preferably laid on each other such that transverse yarns of the one layer are arranged between adjacent transverse yarns of the other layer and vice versa. As a result, the thickness of two successive layers can be reduced. Furthermore, the successive layers are fixed to each other.
  • the inventive solution provides a press felt having a non-woven support structure having both longitudinal and transverse yarns.
  • the longitudinal yarns represent the elements that absorb at least the essential part of the tensile load acting on the press felt.
  • the transverse yarns determine at least the essential part of the transverse stability of the press felt. Since in the solution according to the invention the longitudinal yarns also provide the seam loops, those in the EP0261488 proposed wire helices in the seam area omitted. Since the press felt according to the invention has a support structure which comprises a non-woven textile fabric or even formed from this, it can be produced easily and quickly and thus inexpensively.
  • the solution according to the invention thus combines the advantages of the WO89 / 12717 and EP0261488 known solutions.
  • the self-deposited portions of the fabric may form two or more entire layers. If, for example, the carrier structure has two layers, ie is formed by two layers of the textile fabric extending over the length of the carrier structure, then the two end sections of the flat fabric can be deposited on the middle section of the textile fabric such that they become one Complete the center section completely covering the center section. In this case, therefore, the textile surface is about twice as long as the support structure and the press felt.
  • the support structure may also comprise three layers of the textile fabric or be formed by them.
  • the textile fabric can be divided into three sections of equal length, for example two end sections and one center section laid on top of each other, for example by covering one end section completely on one side of the center section and the other end section on the other side opposite the one side Side of the middle section completely covered.
  • the successive portions of the textile fabric are connected to each other by sewing and / or needling.
  • the sections may, for example, be interconnected by a needled nonwoven structure of staple fibers.
  • a preferred embodiment of the invention provides that one or more transverse yarns is respectively removed from the textile fabric in the region of the cover edges.
  • the textile fabric is preferably a warp knit structure or a leno fabric.
  • the support structure is formed only by the one warp knit structure or the leno fabric.
  • the longitudinal yarns in the support structure preferably extend straight down to the area of the seam loops. Furthermore, preferably extend the Cross yarns in the support structure straight.
  • the term "straight extension in the support structure" is to be understood in the present case that the yarns for providing the support structure do not extend in a curved manner, as is the case, for example, with a woven fabric. The above definition is not intended to exclude that the yarns are curved when the support structure is curved, as is the case, for example, in the case of the carrier structure made endless.
  • the yarns extend mutually curved.
  • the advantage in the straight course of the longitudinal and / or transverse yarns is on the one hand that less yarn material is needed for the production of the textile fabric.
  • such structures are more dimensionally stable than a woven fabric, particularly when used as a press felt, because a structure constructed by straight yarns exhibits less distortion under force in the press nip than a fabric with curved yarns.
  • the longitudinal yarns are monofilament yarns, since in this case the pintle wire can be guided much easier through the connecting channel than if the longitudinal yarns are formed by multifilament yarns.
  • the monofilament yarns forming the longitudinal yarns are formed from or contain a polyamide and / or a polyamide copolymer.
  • the transverse yarns are multifilament yarns and / or staple fiber yarns.
  • the staple fibers of the nonwoven structure can be significantly better anchored than in monofilament yarns.
  • the multifilament yarns are formed from a plurality of monofilament yarns twisted together.
  • 4-ply threads, 6-ply threads, 9-ply threads, or 10-ply threads, to name but a few possible ply threads, are conceivable here.
  • the longitudinal yarns are spaced apart from each other and the distance between adjacent longitudinal yarns corresponds at least to the diameter of the longitudinal yarns.
  • the layers of the textile fabric are preferably laid on each other such that longitudinal yarns of the one layer are arranged between adjacent longitudinal yarns of the other layer and vice versa.
  • the diameters of the transverse yarns are preferably adapted to the diameter of the plug-in wire.
  • a preferred embodiment of the invention therefore provides that the diameter of the transverse yarns substantially corresponds to the diameter of the plug-in wire.
  • the longitudinal yarns extend in the intended machine direction and the transverse yarns in the intended cross-machine direction of the press felt.
  • the method according to the invention may comprise the further step of removing one or more transverse yarns from the textile fabric in the region of the cover edges.
  • the method according to the invention may comprise the step of connecting the layers of the textile fabric forming the carrier structure to one another.
  • the layers it is possible for the layers to be connected to one another only along lines, as may be the case when the layers are stitched together, for example. It is also conceivable to connect the layers with one another in a planar manner, as may be the case, for example, when the layers are glued together.
  • the flat fabric has two transverse edges which limit the length of the fabric and two longitudinal edges which limit the width of the fabric. Furthermore, the textile fabric has an upper side and a lower side opposite thereto.
  • a tubular structure is produced from the textile fabric before step b).

  • step b) is carried out. Furthermore, it is conceivable that after step c) is carried out. Furthermore, it is conceivable that after step c) a fixation the seam loops takes place.
