ABSTRACT:
Increased resistance to unraveling is imparted to a fringe selvage of the type formed by weaving on a fluid weft insertion loom by means of a special selvage construction produced along the opposite side edges of the fabric which combines a pair of twisted binder threads and a juxtaposed leno chain stitch. The binder threads extending along the edges of the warp are opened or separated for the insertion of each weft thread therebetween and then closed and separated in the opposite direction to entwine around the corresponding end of each inserted weft thread while being simultaneously twisted about their own axis and preferably the timing of the closing of the binder threads during the weaving cycle is slightly in advance of the closing of the warp shed itself. The leno chain stitch is situated immediately interior of the binder threads and is constituted of two separate leno strands which are looped under alternating weft strands on either side of a multiplicity of warp strands at each fabric edge and criss crossed over the intervening weft strands, the criss crossing being achieved by reversing the locations of the leno threads preferably while the warp shed itself is in substantially fully open condition.
