Abstract
A woven fabric and a method of forming a seam therein comprising a woven fabric as used for supporting a paper web on a paper making machine. The fabric has interwoven weft and warp strands with the strands in the machine direction being flexible strands incapable of retaining a stable crimp. The improvement in the fabric comprises a plurality of spaced apart replacement monofilament strands having stable crimp characteristics extending in the machine direction and in a seam area for interconnecting opposed ends of the fabric to form an endless belt having a seam which is substantially flat. The replacement strands have crimps of the same configuration as crimps in the machine direction strands of the fabric.
