摘要:
An auxiliary film (4) is applied or fused to a slide fastener chain (1) having a pair of intermeshing rows of coupling elements (2) with an element-free space (3) defined therein. The slide fastener chain (1) is fed by a chain feeder (A) along a feed path (6). The device for applying the auxiliary film (4) includes an ultrasonic horn (8) disposed above the feed path (6), a holder (9) disposed below the feed path (6) and movable toward and away from the ultrasonic horn (8), a stopper (13) disposed in the holder (9) and movable into the element-free space (3) of the slide fastener chain (1), an anvil (14) disposed in the holder (9) and movable toward and away from the ultrasonic horn (8), and a feed roller assembly (31, 36) for supplying an elongate auxiliary film (27) onto the anvil (14). A sensor roller (48) is mounted on the holder (9) for pressed engagement with the elongate auxiliary film (27), the sensor roller (48) having a plurality of circumferentially equally spaced controlling elements (51). A controlling element sensor (52) is disposed near the sensor roller (48) for sensing the controlling elements (51) one at a time and issuing a command signal to keep the chain feeder (A) energized insofar as the controlling element sensor (52) successively senses the controlling elements (51).
摘要:
An elongate separable slide fastener chain (11) is cut off into individual separable slide fasteners, the slide fastener chain (11) having a plurality of longitudinally spaced element-free portions (15) with pin-receptive boxes (18) supported respectively thereon. The slide fastener chain (11) is fed under tension in one direction, and then stopped to release the slide fastener chain (11) of its tension. The reading and trailing ends of one of the boxes (18) are clamped to position the slide fastener chain (11). Then, the slide fastener chain (11) is severed across one of the element-free portions (15) adjacent to the leading end of the box (181. With this arrangement, the slide fastener chain (11) can be positioned accurately for severance and cut off into separable slide fasteners which are sightly in appearance and equal in length.
摘要:
Separable slide fasteners are manufactured from an elongate slide fastener chain (10) composed of a pair of slide fastener stringers (11, 11) having rows of coupling elements (12,12) alternating with element-free portions (13,13) having substantially U-shaped recesses (14, 14) defined in inner edges thereof. The elongate slide fastener chain (10) is fed under tension along a longitudinal path, and the slide fastener stringers (11, 11) are separated from each other. Then, an insertion pin (24) is attached laterally to the inner edge of one of the element-free portions (13), and a box pin (27) is attached laterally to the inner edge of another element-free portion (13) confronting said one element-free portion (13). The insertion pin (24) and the box pin (27) which are laterally aligned with each other are threaded through a slider (32) until certain coupling elements (12, 12) of the slide fastener stringers (11, 11) are interengaged. Then, a box (34) is attached to the box pin (27). An elongate product (46) composed of joined separable slide fasteners may be sewn to successive garment fabrics (48), or may be cut off into individual separable slide fasteners (45).

摘要:
An apparatus (1) for discharging slide fasteners (F) comprises a guide unit (4) disposed on a horizontal longitudinal path downstream of a pair of feed rollers (2), (3) for receiving the slide fasteners (F) therefrom one after another, and a gripping unit (5) disposed on the path downstream of the guide unit (4) for releasably gripping a leading end of the individual slide fastener (F) received in the guide unit (4). The guide unit (4) includes a stationary upper guide member (6) and a lower guide member (7) pivotally movable to open the bottom side of the guide unit (4) to thereby allow the individual slide fasteners (F) therein to fall and hence become suspended from the gripping unit (5).
