Abstract
In a slide fastener in which the row of coupling elements is woven into the tape, the warp yarns are formed in part with binding warp yarns in two or three groups. The warp yarns of the first group pass under double weft insertions between coupling members then over two or three coupling members and then under a coupling member and a double weft of the ground weft yarn underlying same. The binding warp yarns of the second group or arrangement pass over the double wefts between the coupling members and then under the coupling members and the double weft underlying same. A third group or arrangement can also be provided in which the double weft between the coupling members is lifted thereby into a loop and the coupling members are overshot by the binding warp of the third group.
