Abstract A separable bottom end stop having a pin member and a box member is attached to a pair of slide fastener stringers each comprising a row of helically coiled coupling elements supported on and along one side of a marginal edge of a stringer tape, there being a filler cord extending in and along the row of coupling elements. In preparation for the mounting of each of the pin member and the box member, a length of the row of coupling elements is removed, and the exposed filler cord portion and element-free tape portion are pressed together so that the exposed filler cord portion remains in substantial alignment with a portion of the cord which extends over the element-supporting stringer portion, and the element-free tape portion is bent into pressed contact with the exposed filler cord portion. The pin member and the box member are injection-molded on the element-free tape portions and the exposed filler cord portions of the stringers. The attached pin member and pin part of the box member lie substantially flush with the fastener stringers so that the slider can slide smoothly onto the pin member and pin part.
A method of attaching a separable bottom end stop having a pin member and a box member including pin part to a pair of slide fastener stringers including a pair of stringer tapes supporting on and along one sides of their confronting marginal edges a pair of rows of helically coiled elements having filler cords extending therethrough, comprising the steps of: (a) removing a length of each of said rows of helically coiled elements from said stringer tapes to provide a pair of element-free tape portions with exposed portions of said filler cords left thereon; (b) bending with heat and pressure said pair of element-free tape portions into pressed contact with said exposed portions of the filler cords, said exposed portions being held in substantial alignment with those portions of said filler cords which are disposed in said rows of helically coiled elements; and (c) mounting said pin member and said box member on said pair of element-free tape portions, respectively, said pin member and said pin part being substantially equal in thickness to and lying substantially flush with element-supporting portions of said slide fastener stringers.
