Title:
REINFORCED WARP LOOP BONDED SEAM FOR AN INDUSTRIAL TEXTILE
Document Type and Number:
WIPO Patent Application WO/2011/022831
Kind Code:
A4
Abstract:
A seaming area for a woven industrial fabric, a fabric, and a method of providing a seaming area and seam. The fabric comprises at least a first set of warp yarns interwoven with weft yarns, either in a single layer, or multiple layers in which the warp yarns can optionally be stacked. At each seaming area, yarns of a first group pass around and in contact with the fabric edge, and yarns of a second group pass around the fabric edge to form protruding loops. Free ends of the warp yarns are bonded to the fabric body, over warp yarns or weft yarns, or combinations thereof. Opposing fabric ends are brought together, and the loops interdigitated to be joined by a pintle or coil to render the fabric endless. The seaming area and the method provide increased seam strength and reliability, with significant reduction of time and costs of manufacture.
