摘要： An apparatus for manufacturing a fastener chain having solid sections by repeating the steps of providing a tape having perforated sections which include holes punched in a longitudinal edge of the tape, and solid sections, which are free of holes, alternating with the perforated sections, supplying the tape so that the perforated section thereof is placed between a stationary mold and movable mold, applying tension to the tape to stretch it, and then injection-molding fastener elements onto the tape at the holes. Stretching of the tape is accomplished by a sprocket wheel provided adjacent a freely rotatable drum. Teeth on the circumferential surface of the sprocket wheel are caused to recede below the circumferential surface of the freely rotatable drum when a solid section of the tape passes over the drum.

摘要： An apparatus (20) comprises a heated die wheel (22) having a circumferential groove (25), and a series of circumferentially spaced bending, punching and hammering units (28 - 30) disposed along the periphery of the die wheel (22) and having respective working heads (41a, 54, 71) projectable into the groove (25) to deform a filament (a) of thermoplastic material into a row of continuous zigzag coupling elements (g). Each of the working heads (41a, 54, 71) is movable in a direction parallel to the axis of the die wheel (22) in agreement with the lateral oscillation of the groove (25) when the die wheel (22) is rotated.

摘要： An apparatus for manufacturing a continuous slide fastener stringer (11) including a plurality of longitudinally spaced rows of injection-molded coupling elements (13) secured to a stringer tape (12) along a longitudinal edge thereof with a plurality of element-free portions between the successive rows of the injection-molded coupling elements, includes a fixed feeler (70) disposed on the one of a pair of relatively movable mold members (14, 15) adjacent to a leading mold cavity therein for detecting a trailing end (73) of the injection-molded coupling elements, and a movable feeler t74) disposed on the one mold member (15) downstream of the fixed feeler (70) at a distance (W) substantially equal to the length of the element-free portions of the stringer. The movable feeler (74) is driven by a driving mechanism to selectively project or retract from a mold surface (26) of the one mold member (15) in interlocking relation with a feed mechanism (63, 66) which intermittently feeds the stringer tape by a predetermined distance.

摘要： A row of slide fastener coupling elements (64) of synthetic resin or meta! is pressed between a pair of first and second presser rolls (18, 24; having first and second confronting presser surfaces (34, 39) engaging legs of the coupling elements (64). The first and second presser surfaces (34, 39) have closest confronting portions spaced from each other by a distance (W) equal to the width of each of the coupling elements (64). The second presser roll (24) is displaceable with respect to the first presser roll (18) to vary the distance (W). The first presser roll (18) has a spur gear (35) held in mesh with a pin gear (41) on the second presser roll (24). The first and second presser rolls (18,24) can be rotated in synchronism by the spur gear (35) and the pin gear (41) even when the second presser roll (24) is displaced relatively to the first presser roll (18). The first and second presser rolls (18, 24) also have partition ridges (47, 48) for meshing engagement with the legs to keep them spaced apart at equal intervals. One of the first and second presser rolls (18, 24) has a third presser surface (50) for engagement with coupling heads (78). Another presser roll (51) has a fourth presser surface (53) in confronting relation to the third presser surface (50) for pressing the coupling elements (64) toward the third presser surface (50).

摘要： In a reinforcing-film applying apparatus for use in production of separable slide fasteners, there are a first working station where a shaping die (50) and a coacting ultrasonic horn (49) are located, and a second working station where a heating die (78) and a coacting heating punch (77) are located, the first and second working stations being spaced apart remotely from one another along a longitudinal path (22) of a slide fastener chain (5). When one of successive pairs of blank tape portions (8) arrives at the first working station, a reinforcing film piece (9) is placed on the fastener chain (5) across the pair of blank tape portions (8), whereupon the shaping die (50) and the ultrasonic horn (48) are moved toward one another to fuse the reinforcing film piece (9) to the pair of blank tape portions (8) only at their inner marginal areas and also to shape such fused marginal portions so as to provide therealong a pair of pin-like members (10, 11) to which a pin and a box of a separable bottom end stop are to be attached. After that, when the pair of blank tape portions (8) with the reinforcing film piece (9) partially fused thereto arrives at the second station as the fastener chain (5) is further moved along the path (22), the heating die (78) and punch (77) are moved toward one another to apply pressure and heat to the pair of blank tape portions (8) and the reinforcing film piece (9) thereon at their superposed areas except the pin-like members (10, 11).
