Abstract
Abstract A woven textile fabric and seam is disclosed for joining dryer fabrics and the like papermaking clothing constructed of multiply woven fabric belting wherein each of the ends of the belting is separated into continuous woven superposed plys permitting insertion and securing of seam webbing between the plys at each end of the belting. The seam webbing is illustrated sandwiched between the separated plys and completely enclosed therein when the plys and webbing are secured together so that interruption of the otherwise continuous belting is minimized. Having affixed the webbing at ends of the woven fabric in this manner, pintle loops may be interlaced and fastened securely together by the insertion of pintle material. One of the separated plys may be advantageously woven to provide pintle loops when folded upon itself.
