ABSTRACT:
A method of forming a so-called space where fastener elements have been removed from a slide fastener chain in which fastener elements of synthetic resin have been woven into the edges of fastener tapes comprising disengaging right and left stringers from each other, setting each stringer on a working bed, keeping fixed all fastener elements in the space forming area of each stringer on the working bed by respective press pieces at their engaging heads, cutting at least the connecting threads extending through the legs of each fastener element at the front and rear end of the space forming area of each stringer, then pulling the fastener tapes away from the respective press pieces and thus pulling out the binding warp threads, core string and connecting threads from the fastener elements, so as to remove the fastener elements from each fastener tape and keep the binding warp threads, core string and connecting threads extended along the space forming area in the weft loops.
