Abstract
Abstract A seam for an endless woven fabric wherein end portions of weft strands project from the ends of the fabric and are woven together in the seam with a plurality of added warp strands so that the warp end portions projecting from one end of the fabric and those from the other end of the fabric to be joined meet at a termination point and these termination points are both laterally and longitudinally spaced from one another.
