Abstract: A reverse-separating device for a slide fastener, comprises a retainer pin 5, a separable pin 6 both made of metal and a reverse-separating slider 3. Each of the retainer pin 5 and the separable pin 6 is of a U-shaped cross-section and has a slit 18 formed along its front edge. At the lower end of the slit 18, the retainer pin 5 projects rearward beyond the slit 18 to thus provide a loop-like stopper 22 for engagement with the flange 31 of the reverse-separating slider 3. Once the retainer pin 5 is inserted into the reverse-separating slider 3, the retainer pin 5 is firmly retained by three parts of the reverse-separating slider 3. The separable pin 6 has a projecting ledge 28 formed on the upper end the projecting fin 27 so as to project laterally therefrom. The projecting ledge 28 of the separable pin 6 is adapted to abut against the upper end of the projecting fin 25 of the retainer pin 5 and thus prevent the separable pin 6 from moving further into the reverse-separating slider 3.

Abstract: A stopper portion has a minute protrusion on part of an outer peripheral face except a side face in the length direction of a fastener tape. This protrusion is a rib-like protrusion extended linearly in the length direction of the fastener tape formed on a vertex of the surface of a bent portion, a protrusion extended so as to be expanded in a curved shape in the length direction of the fastener tape or a rib-like protrusion protruded along a boundary portion between the bent portion of the stopper portion and a bottom face thereof. Existence of this protrusion not only reduces a sliding resistance when the slider is started but also eliminates prickly feeling and feeling of disharmony originating from a shape of an upper stopper which is a kind of the conventional stopper portion.

Abstract: A stop device for upper stops and a pull of a Nylon zipper has an upper stop formed by a left stop and a right stop; a pull being installed on one end of a zipper strip. The upper end surfaces and the bottom of the left stop and right stop are formed with protruded stop blocks, and the pull has a left and a right teeth channel, tops or bottoms of a respective teeth channel are formed with stop grooves.

Abstract: A method of attaching bottom stops of a generally H-shaped cross section to a slide fastener chain. One of successive spaced pairs of opposed blank tape portions of the fastener chain is spread apart. A bottom stop, which has two pairs of gripping legs, is placed between the spread pair of opposed blank tape portions. The spread pair of opposed blank tape portions is then released and thereby allowed to come toward each other until a pair of opposed blank beaded tape edges are threaded one through a space between each pair of the gripping legs of the bottom stop. Then, the blank beaded tape edges are compressed against the bottom stop on opposite sides. Finally, the gripping legs of each pair are clinched about the compressed beaded edge of a respective one of the stringer tapes. An apparatus for carrying this method is also disclosed.
