摘要： A method of welding a row of interconnected thermoplastic coupling elements for slide fasteners at opposed leg portions of each coupling element with the use of an ultrasonic horn. The method comprises: pressing the opposed leg portions of the coupling elements against the ultrasonic horn on its opposite sides while the coupling elements are being fed at constant speed; concurrently with this pressing step, softening the opposed leg portions of the coupling elements at their confronting inner surfaces by ultrasonically vibrating the ultrasonic horn in a direction parallel to the confronting inner surfaces; and pressing the opposed leg portions of the coupling elements, after the latter is disengaged from the ultrasonic horn, against each other so as to be united at the confronting inner surfaces that have been softened. An apparatus for carrying the above method into practice efficiently and accurately is also disclosed.

摘要： . Several embodiments are disclosed of a bottom stop of a slide fastener of the type comprised of three members, two secured to one stringer tape and one to the other, such that once the three members are passed through the Y-shaped channel, they interengage to form a unitary stop member that cannot be disassembled. Contrary to prior art wherein at least one part of the stop member is of a greater maximum width than the maximum width of the respective channel of the slider, to secure abuttive opposition to the movement of the slider, the invention provides elements that can all pass relatively smoothly through the respective slider channels when assembling the stop. The abutting action is achieved by a concave protrusion on one of the members by its engagement with the neck of the slider. The interengagement of the members is such as to prevent separation of the assembled stop both transversely of and perpendicularly to the fastener rows, while facilitating the assembling by avoiding forced passage of at least one stop member through the slider and the resulting damage to at least one of the members to the channel of the slider or to both, frequently encountered in prior art stops of this type.

摘要： A separable slide fastener comprises a pair of oppositely disposed stringers each having a support tape and a fastener element formed from a plastic monofilament into a continuous structure having coupling head portions, upper legs, lower legs and connecting heel portions and secured by sewn seams to a longitudinal inner edge of the respective tape, a reinforcing core extending through the coiled fastener element and a slider having a pair of branched guide channels defined between its flanges and diamond. A group of successive loops of the fastener element are fused together over a predetermined length at one end of the fastener and cut closely along the sewn seams to provide a pair of integrated pin members on the respective stringers. The group of fused loops on one stringer has a plurality of coupling head portions transferred from the other stringer. One of the pin members includes a locking lug having a transverse length substantially equal to or slightly greater than the width of one of the branched guide channels of the slider.

摘要： An improved slide fastener assembly incorporating an arrangement in which the stringer tapes of the fastener may be sewn into a garment prior to assembly with the slider and wherein the slider may then be assembled to the stringers without force. Upon such assembly the parts remain assembled by virtue of cooperating fastener elements having projecting portions that interengage with each other and the slider to prevent retrograde movement back out of the slider following assembly.

摘要： A separable slide fastener is disclosed which is provided with a separable end stop assembly comprising a pin member on one stringer and a socket member on the other stringer, both members being releasably interengageable to couple the stringer. Each stringer has a portion of its fabric tape raised above the general plane of the tape and anchored within the stop assembly. The pin part of the assembly is reinforced by a sleeve which has a thickened portion extending closely along a longitudinal marginal edge of the pin.

摘要： A pair of continuous slide fastener stringers having a pair of stringers tapes including thermoplastic synthetic fibers and a pair of integrated rows of fastener elements mounted on the confronting edges of the stringer tapes are provided with an element-free gap therein and are cut off transversely of the element-free gap to produce an individual slide fastener length with ultrasonic processing means. Simultaneously, the cut edges and ends are fused, and top and bottom end stops are mounted respectively on the fastener slide stringers and the slide fastener length with heat induced by the ultrasonic processing means. The interengaged element rows while advancing are introduced into a slider through its mouth which is supported on a slider holder, with portions of the top end stop being forcibly flexed away from each other by the body of the slider, thereby allowing the top end stop to move past the slider.

摘要： A bridge top end stop for slide fasteners is provided for preventing a slider from running off of the upper end of the slide fastener, which top stop has a substantially horseshoe-shaped body including a channel or opening through which a beaded edge of a fastener tape is threaded to position the top stop on the fastener. The top stop body is secured together into positive engagement with the beaded edge, whereupon the channel is completely filled up by the beaded edge.

摘要： A top stop of thermoplastic material is thermally fused onto a plurality of topmost scoops of a continuous coupling element on each stringer tape to limit the upward or fastener closing movement of the slider. The top stop is substantially L-shaped, comprising a longitudinal portion embracing the coupling heads of several topmost scoops and a transverse portion bent outwardly from the upper extremity of the longitudinal portion to secure the stitching thread to the extreme endmost scoop or scoops.

摘要： A slide fastener slider having on its upper wing a hook-shaped lug to which a pull tab is pivotally connected by snap fitting operation. There is also provided on the upper wing a projection spaced apart from the lug and adapted to fit in an opening formed in the pull tab when the latter is moved down into contact with the slider upper wing, thereby preventing the pull tab from becoming displaced relative to the horizontal axis of the slider body.
