  • Patent number: 3976106
    Abstract: A helical series of slide fastener links is fed parallel to warp threads and the filling threads are inserted to weave the tape. The helical or meandering series of slide fastener links is extended adjacent to the zero plane of the weaving machine and is moved along a straight line and without formation of a shed during the weaving operation. At least two joining warp threads are warped which are spaced from the series of slide fastener links and disposed before the coupling surfaces thereof. Warp threads of the backing woven fabric are warped on the other side of the series of slide fastener links. Two joining warp threads lying in upper and lower sheds are formed into a first shed. The warp threads of the backing woven fabric and any remaining joining warp threads lying in a middle shed and the lower shed are formed into a second shed.
