ABSTRACT:
Individual coupling members, molded from synthetic resin onto a support tape and straddling an edge thereof are removed, e.g. to enable the mounting of a slider, the stitching of the tape to a fabric or other carrier or for the formation of end-stop members, by applying orthogonal to the stringer plane a pressure causing plastic deformation and flow of the material of the coupling member which results in a spreading of the fastening shanks thereof. The tape is then withdrawn from between the legs or shanks which have been thus spread apart or the coupling member is withdrawn from the edge of the tape generally in the aforementioned plane.
