| 20100252219 | SEAMABLE PRESS FELT WITH FLAT MANUFACTURED CARRIER STRUCTURE WHICH IS NOT WOVEN - 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. | 10-07-2010 |
