CONTINUOUS MOLDED SLIDE FASTENER STRINGER AND METHOD AND APPARATUS FOR MANUFACTURE

摘要

Interconnecting threads for continuous molded coupling elements are used as load bearing members securing the coupling elements to a support tape. The strength of the union of the connecting threads with the molded coupling elements is increased such as by displacing central portions of embedded segments of the connecting threads deeper into leg portions of the coupling elements or providing a plurality of spaced connecting threads for each leg portion of a pair of leg portions of each element.
