Abstract:
The present invention relates to a press felt for a machine for the production and/or processing of a fibrous web including a carrier structure which fundamentally influences the dimensional stability of the felt. The carrier structure includes a flat manufactured textile fabric formed from longitudinal threads, transverse threads crossing the longitudinal threads, and sewing threads which connect the longitudinal and transverse threads with each other at the crossing points. The textile fabric is longer than the carrier structure and is laid onto itself in sections such that the carrier structure is formed by several layers of the textile fabric, extending respectively along the entire length of the carrier structure. The layers are connected with each other, at least in sections. Due to the placement of the sections of the textile fabric on top of each other, turned over edges which extend transversely to the longitudinal direction of the carrier structure are formed defining transverse ends of the carrier structure. In an area of the turned over edges, the longitudinal threads have a curved progression to form seam loops on the respective transverse ends, whereby the carrier structure is seamable in a paper machine in that the two transverse ends of the carrier structure are brought together to make the carrier structure continuous and the seam loops are meshed with each other, thus forming a connecting channel extending in the cross direction of the carrier structure. To make the carrier structure continuous, a pintle wire is inserted through the connecting channel.

The invention relates to paper machine clothing, in particular a press felt for a paper, cardboard or tissue machine, comprising a load absorbing base structure that extends in longitudinal and cross direction of the clothing and which comprises, and in particular is formed by: a) a longitudinal reinforcement module substantially providing the dimensional stability in longitudinal direction of the clothing, and b) a transverse reinforcement module substantially providing the dimensional stability in cross direction of the clothing, whereby the transverse reinforcement module and the longitudinal reinforcement module are arranged one on top of the other and are interconnected with each other. The invention is characterized in that the transverse reinforcement module is a warp knit fabric which is composed of at least one system of weft threads arranged parallel to each other, and at least one system of stitch forming sewing threads which extends substantially perpendicular thereto into which the weft threads are integrated to form a textile fabric, wherein the weft threads extend diagonally to the longitudinal direction of the clothing and have a greater flexural strength than the sewing threads.
Abstract:
A paper machine clothing, in particular a press felt for a paper, cardboard or tissue machine, includes a load bearing base structure that extends in the longitudinal and cross directions of the clothing and which is formed, for example from a longitudinal reinforcement module substantially providing the dimensional stability in longitudinal direction of the clothing, and a transverse reinforcement module substantially providing the dimensional stability in the cross direction of the clothing, which is arranged on the longitudinal reinforcement module and is connected with same. The transverse reinforcement module is a warp knit fabric, which includes at least one system of warp threads arranged parallel to each other and one system of stitch-forming sewing threads extending substantially perpendicular thereto into which the warp threads are integrated to form a textile fabric. The warp threads extend transversely to the longitudinal direction of the clothing and have a greater flexural strength than the sewing threads.
Abstract:
The invention relates to a clothing especially a press felt for a paper, cardboard or tissue machine with a nonwoven structure comprising staple fibers and which provides the paper and running side of the clothing and with a base structure which is embedded into the nonwoven structure, whereby the base structure comprises a warp knit structure which has sewing threads and reinforcing threads extending lengthways parallel to each other and which have a greater flexural strength than the sewing threads, whereby the sewing threads form loops into which the reinforcing threads are tied thereby forming the warp knit structure. The invention is characterized in that an intermediate layer is arranged at the warp knit structure which is connected with the reinforcing threads by way of the sewing threads.

Abstract:
A scaffold for tissue culture and cell culture and for producing implant materials, in particular bone, cartilage or skin replacements or extra-corporal organ replacements or for other applications in medicine or biotechnology is made of biocompatible materials. It has at least one base material which is electrostatically flocked with fibers on at least one side. Through the electrostatic flocking the fibers are arranged almost perpendicularly on the surface of the base material and exhibits a high fiber pull-out resistance. The scaffold provides an elastic growth lattice, which is stable against compression, for cell colonization in vitro or the ingrowth of cells in vivo. Implants or implant materials can be produced with the scaffold.
