摘要 |
A slide fastener has a pair of tapes along confronting edges of which are provided respective rows of coupling elements in a ladder configuration with individual members being affixed together by a continuous textile strand, as one-arm rungs of the ladder. Each coupling member is molded unitarily and unbent, and comprises an upper portion and a lower portion separated by a plane parallel to a slide fastener plane. The head of each coupling member lies above this plane and is mushroom-shaped to have a neck reaching inwardly toward the respective edge of the tape. Flush with this plane but on the lower half of the coupling member are a pair of ledges which function to absorb forces transverse to this plane. The connecting yarn is embedded in the upper half which can be provided for connection to the tape. |
