Abstract
Coil-like or zigzag-like linear fastener elements formed of synthetic fiber mono-filaments are attached such that coupling heads project from a side edge of a fastener tape and at least one coupling head thereof located at a top end is moved to the inside of the fastener tape so as to substantially coincide with the side edge. Then, the fastener element is fused to the fastener tape in a state in which an inverted portion project inwardly while the coupling heads are in a non-coupling condition, so as to form a top end stop. The top end stop formed of the linear fastener element includes plasticity and provides an excellent tactile feeling without any burr on the surface thereof.
Claims9
A top end stop of a linear slide fastener, wherein linear fastener element rows are attached to side edges of fastener tapes or bent side edges bent in parallel along the side edges, each of the linear fastener element rows comprises plural linear fastener elements, each of the liner fastener elements comprises a coupling head and an inverted portion connecting adjacent linear fastener elements to each other,
- wherein the inverted portion of at least one linear fastener element at a top end portion of each linear fastener element row is projected to an inside of each of the fastener tapes more inwardly compared to a position of the inverted portions of the other linear fastener elements, the coupling head is placed along the side edge of each fastener tape or the bent side edge bent in parallel along the side edge, and each linear fastener element and each fastener tape are fused together and fixed,
- wherein said at least one linear fastener element at the top end portion of each linear fastener element row is entirely placed on the inside of each fastener tape, and
- wherein each of the linear fastener elements other than said at least one fastener element at the top end portion of each linear fastener element row comprises the coupling head projecting from the side edge or the bent side edge,
- wherein right and left linear fastener elements fused together and fixed on the fastener tapes comprise a stop mechanism by bringing right and left inverted portions into contact with inside wall faces of flanges on a shoulder side of a slider while respective opposing coupling heads are in a non-coupling condition so as to form the top end stop.
