摘要:
A fastener stringer is provided with a fixing section in which at least one of a first and second half sections is fixed to a fastener tape and a tapered extending section which extends from the fixing section toward the outside of the tape. A first side face and a second side face in the tape length direction in the fixing section have concave surfaces which curve in a concave shape so as to gradually increase from an element surface of a fastener element toward the fastener tape. Accordingly, each fastener element can exhibit an appearance close to a metallic fastener element and a locking mechanism of a slider can be made to function stably.

A method and apparatus for the manufacture of slide fastener carrying a discrete formation of differently colored elements in selected orders. Method and apparatus are disclosed for feeding a plurality of colored elements selectively one at a time in a vertical direction and transferring one such element horizontally to a predetermined position for gravity fall onto a stringer tape.

A garment-fastener assembling apparatus includes a drive mechanism for reciprocating an optical position indicator toward and away from an indicating position located in registry with the path of movement of a punch. The drive mechanism is constructed to operate under direct control of the movement of the ram so that the position indicator is reciprocated without interference with the punch or any other movable part of the apparatus and without causing prolongation of the cycle time of the apparatus.

A stringer combining apparatus includes a stringer combining guide section. The guide section has an outer guide member located at the junction of guide groove portions which in combination constitute a Y-shaped guide groove, the member being made resiliently movable in the outward direction, thereby allowing the passage of even members other than fastener elements attached to a stringer. The apparatus further includes a conveyor device for conveying the stringers through the guide section. The guide section is made movable in the direction parallel with the moving direction of the stringers. The guide section is moved by a fluid-pressure cylinder device. Alternatively, the guide section is pressed by the action of a spring toward the downstream side in terms of the conveying direction of the stringers and is maintained at a predetermined operation position by a stopper against the pressing force of the spring and is further made movable against the pressing force of the spring when a force of a predetermined magnitude acts on the guide section toward the upstream side.

A fastener assembling apparatus includes a shock absorber disposed between a frame of the apparatus and one lever of a toggle joint, the other lever of the toggle joint being connected to a punch assembly. The shock absorber is elastically deformable to absorb shock forces caused in the punch assembly by pressing of a pair of fastener elements between the punch assembly and a cooperating die assembly. The shock absorber may have means for adjusting the stroke of the punch assembly for accommodating changes in thicknesses of both the fastener elements and a garment to which the fastener elements are attached.

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.

A slide fastener stringer includes a row of helically coiled or zig-zag coupling elements of thermoplastic synthetic resin with a reinforcing core extending longitudinally therethrough. The coupling elements are secured to one surface of a stringer tape by sewing threads having portions running across and over upper legs of the coupling elements. Some of the coupling elements are cut off to provide an element-free space on the stringer tape. A terminal or endmost complete coupling element disposed adjacent to the element-free space has a free-ended connecting portion remote from a longitudinal edge of the stringer tape. To form an end of the slide fastener stringer, the free-ended connecting end portion of the terminal coupling element is fused to the stringer tape, and at the same time, the upper leg of the terminal coupling element is heated and pressed toward the stringer tape. A device for forming such a stringer end includes a stringer rest for supporting the end of the stringer, and a heating presser having a first surface for heating and pressing the free-ended connecting portion of the terminal coupling element against the stringer tape and a second surface for heating and pressing the upper leg of the terminal coupling element toward the stringer tape. The first surface projects beyond the second surface toward the stringer rest.

A method of controlling the operation of applying discrete coupling elements one at a time onto a stringer tape, which comprises counting the number N.sub.1 of coupling elements entering a chute and comparing the number N.sub.1 thus counted with the number R of reovlutions of a motor driving a means of applying the elements to the tape thereby incessantly monitoring the inventory Nc of the elements in the chute.

A pair of top end stops is attached to respective beaded edges of a pair of stringer tapes of a slide fastener chain which is fed along a feed path. A punch and die assembly disposed above the feed path has a pair of pockets for gripping the top end stops, respectively. The die assembly being movable between a horizontal position for receiving the top end stops and a vertical position directly above an attaching position for attaching the top end stops to the stringer tapes. The punch and die assembly is moved from the horizontal position to the vertical position, and then lowered from the vertical position into the attaching position across the feed path. The stringer tapes are spread apart from each other by a thrust lever, and then the punch and die assembly is pressed by a pusher rod to clinch the top end stops gripped in the pockets on the respective beaded edges of the stringer tapes.

In a method of attaching parts of a separable bottom end assembly to a continuous slide fastener chain, a box or insertion pin, in the shape of a channel, of a separable bottom end assembly is threaded onto one of longitudinally spaced successive element-free portions of one longitudinal edge of a continuous slide fastener stringer in an edgewise direction while the one element-free portion is kept stationary at an attaching station in a substantially horizontal path of the fastener stringer as the latter is at rest. The thus threaded pin is then fixedly secured to the one element-free portion by being compressed into a final shape therearound.
