摘要:
A woven slide fastener stringer comprises a row of filamentary coupling elements fastened to a stringer tape by a binding thread system composed of weft and warp threads intertwined with the coupling elements and the stringer tape. At leat a pair of warp threads symmetrically overlie and underlie upper and lower legs of the coupling elements and cross each other between adjacent coupling elements. The weft threads of the binding thread system are interlooped with the symmetrically running warp threads at the upper and lower legs of the coupling elements. With such an arrangement, coupling heads connected to the coupling element legs are disposed substantially perpendicularly to the plane of the stringer tape for increased coupling strength necessary to keep opposite rows of coupling elements securely interengaged against accidental separation. An apparatus for manufacturing such a woven slide fastener stringer includes independent heddles and filling inserters for supplying warp and weft threads of such a binding thread system.
