摘要:
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.

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).

A fastener slider inserting apparatus inserts a slider into a continuous concealed fastener chain alternately having element rows interlocked with each other and space portions in which no element is present. The apparatus has a slider holding device which includes: a slider holder (31) which is adapted to receive a slider from a slider supply device (32) and to support the same, with a pull of the slider hanging down; a device which moves the holder between an upper position where the slider is upwardly separate from the fastener chain and a lower position where the slider is in contact with the fastener chain so that bead portions of the fastener chain are allowed to be inserted into a channel in the slider; a pull guide (63) having a pull groove which houses the pull of the slider; and a device (61,62) which moves the pull guide between a lower position where the pull guide is downwardly separate from the fastener chain and an upper position where the pull guide extends such as to pass through one of the space portions of the fastener chain and to come in contact with or be adjacent to the slider within the slider holder. When the pull guide (63) is moved from the upper position to the lower position, the slider holder is moved from the upper position to the lower position together with the pull guide (63).

An apparatus (100), for automatically processing a slide fastener chain (1) to which a succession of fly strips (1) is attached, comprises an intermittently operative feed unit (30) for feeding the fastener chain (1) along a longitudinal path (9), a first cutting unit (10) disposed upstream of the feed unit (30) for forming element-free gaps (8) in the fastener chain (1) near or at ends of successive fly strips (4), and a second cutting unit (50) disposed downstream of the feed unit (30) for severing the fastener chain (1) at such element-free portions. The apparatus (100) also includes a measuring unit (60) disposed upstream of the first cutting unit (10) for measuring the amount of the fastener chain (1) having been fed by the feed unit (30), and a detector (70) disposed between the first cutting unit (10) and the measuring unit (60) for detecting ends of successive fly strips (4). The measuring unit (60) and the detector (70) are electrically connected to a processing circuit (80) which produces output signals to control the intermittent operation of the feed unit (30) in timed relation with the operations of the first and second cutting units (10), (50).

Disclosed herein are method and apparatus for attaching pin fittings to a slide fastener having a separable end stop, in which a pin fitting is attached to a slide fastener by the steps of holding the pin fitting by a pin fitting holder (26), moving the stringer tape (1) gripped by a gripper (3,4) for introducing a core portion of the tape into the pin fitting, and deforming the pin fitting to secure it to the core portion. In these method and apparatus, attachment by deforming the pin fitting is performed under a condition where a first fastener element (52,53) of a fastener element row affixed to the stringer is abutted against an end portion of the pin fitting with a force of a predetermined magnitude.

A longitudinally gapped, continuous slide fastener chain (21) with sliders (30) slidably mounted is longitudinally fed along by a feed roller (34) through an apparatus (33) including a top stop applicator mechanism (110). When the slider (30) on a pair of coupling element rows (24,25) is sensed by a slider sensor (127), the feed roller (34) is stopped and a chain stop lever (84) is lowered into a gap (29) adjacent to the coupling element rows (24,25). The feed roller (34) is rotated again to feed the slide fastener chain (21) again to displace the chain stop lever (84) slightly downstream by engagement with a bottom stop (28) attached to a following length of coupling element rows (24,25). When the slide fastener chain (21) is stopped again, the chain deflector (99) is lowered transversely into the path of the slide fastener chain (21) to depress the chain (21) so that the chain (21) located downstream of the chain deflector (99) is pulled back until the ends of the coupling element rows (24,25) where top stops (31,32) are to be applied are bought into clinching dies (46,47). After the chain deflector (99) has been fully lowered, a main shaft (115) is rotated through one revolution for actuating a top stop cutter (112) to cut a pair of top stop blanks out of a flat wire bar (130) and lowering a curling punch (114) to clinch top stops (31,32) around the rows of coupling elements (24,25) at their ends in the clinching dies (46,47). The foregoing cycle of top stop attaching operation is repeated for successively attaching top stops (31,32) to the slide fasteer chain (21).

摘要:
A method and apparatus for attaching a reinforcing tape to an intermittent fastener chain. A fastener chain having alternate element-containing and element-free sections is advanced intermittently in the longitudinal direction thereof. When the fastener chain is stopped, a strip of reinforcing tape is moved transversely across an element-free section from the side edge thereof and is folded over the side edge, after which pressure is applied to the side edge from the top and bottom sides of the chain to adhere the strip of reinforcing tape to the side edge. The attachment of the tape is divided into a first attaching step of applying pressure solelytothevicinity ofthe side edge from both sides of the fastener chain, and a second attaching step of applying pressure to the entire portion of the element-free section having the strip of reinforcing tape folded thereon, from both sides of the fastener chain.
