    摘要： A slide fastener shortening method for shortening a slide fastener with rows of fastener elements made of synthetic resin from a predetermined length of the slide fastener into a desired short length thereof. In an illustrative embodiment, the present invention includes the steps of: inserting removers disposed at the position orthogonal to the fastener tape into the interstice between fastener elements at a position approximately corresponding to the fastener element length required in a product slide fastener of the desired short length, pressing unnecessary fastener elements of the extra length adjacent to the removers along the proper length to thin the fastener elements to permit easy deformation, pulling the slide fastener in the longitudinal direction to strip off the compressed and deformed fastener elements with the removers and to remove them from each fastener tape so as to form space sections free of fastener elements, and cutting them within the space sections into the desired short length to obtain the product slide fastener of the desired short length. This method may also comprise the steps of, stripping the pressed and deformed fastener elements form the fastener tape with the remover so as to form the space sections free of the fastener elements, and cutting the slide fastener within the space sections into the desired short length to obtain the product slide fastener of the desired short length after attaching upper ends to the fastener element rows of the product slide fastener of the desired short length.

    摘要： Continuous or other lengths of flat back plastic filament coil slide fastener chain is gapped in such a manner that the tape ends produced by the gapping are scrap-free and undamaged. The slide fastener chain to be gapped is held in a laterally taut state in a die and anvil apparatus while the interengaged coil elements are forced upwardly into engagement with blades which cleanly sever the outer leg portions of the coil elements, which leg portions are conveyed upwardly by suction. During the outer leg severing operation, the slide fastener chain is further stretched laterally and caused to spread apart slightly at its center line. The center portion of the chain between the removed coil outer leg portions is received in a control and stabilizing channel between the severing blades while an ascending punch acts on the remaining interior coupling portions of the coil elements and removes them cleanly from the tapes without damaging the tapes. The removed interior coupling portions of the coil elements are also conveyed upwardly by suction away from the gapping zone. Filament coil fragments remaining near one or both ends of the gap are removed by projections on each end of the punch.

    摘要： The present invention concerns a slide fastener making machine designed to produce space sections of required span devoid of coupling elements at predetermined intervals in the interengaged slide fastener chain and a method for the same.The present apparatus includes: die means facing the fastener tapes for supporting the slide fastener chain horizontally; punch means disposed on the coupling elements side and being reciprocably movable toward the coupling element, said punch means having at the end surface a pair of laterally spaced apart cutting edges for cutting the upper leg portion of the pair of interengaged coupling elements at the connecting reversed portion side of the sewing thread and a gripping projection disposed centrally between the pair of the cutting edges for pressing the upper leg portions adjacent the interengaging head portions of the interengaged coupling elements; ejector means disposed in the die means reciprocably movable toward the gripping projection of the punch means, said punch means being upwardly movable in response to the upward movement of the ejector means while the upper leg portions adjacent to the interengaging head portions of the interengaged coupling elements is gripped between the edge of the ejector means and the gripping projection of the punch means; and means for holding the pair of fastener tapes. The coupling elements cut by the cutting edges or the dismembered coil fragments are suitable flattened by the gripping projection of the punch and the ejector so that they are released of the clinching tension of the sewing thread and get loose enough to be pulled out easily.
