A cloth pick-up apparatus is used which comprises pressing mechanism for a pressing one end of the top cloth piece from the upper side, a catch roller having on a part of its circumferential surface catch needles and movable toward and away from the other end of the top cloth piece, the catch roller being adapted to be driven for rotation to feed the top cloth piece in a direction remote from the pressing mechanism, a feed roller rotatable in timed relation with the catch roller, and a pressure roller movable toward and away from a cloth-piece-feed surface of the feed roller and rotatable in cooperation with the feed roller. The catch roller is rotated touching one end of front face of the cloth pieces with the other end of the cloth piece pressed by the pressing roller so that the upper most cloth piece is caught by the catch needles and, at the same time, is raised. Then the cloth pieces are fed one by one to the next station as the individual cloth piece is clamped between the feed surfaces of the feed roller in driven rotation and the pressure roller.

The apparatus additionally includes a slider holder retainer disposed on the path of vertical movement of the slider holder and adapted for retaining the slider holder stably, as the slider holder assumes the uppermost position for the threading operation, so as to prevent the slider holder from being wobbled and pulled downstream by the fabric-pieced slide fastener chain during the threading thereof through the slider.

Slider holding apparatus

A method of feeding an array of sliders one at a time for application onto a stringer chain is disclosed, which method comprises holding the array of slider linearly in a tilted position relative to a horizontal path of travel of the stringer chain so that the sliders can slide down smoothly by gravity, orienting a leading slider to lie flush with the horizontal path of the chain and transferring the leading slider over to a slider applying station. An apparatus is also disclosed for carrying this method into practice.

A method of stacking a multiplicity of fabric strips attached with a slide fastener chain one upon another is disclosed, which comprises folding each of the strips in halves along the longitudinal axis of the fastener chain, clamping the fabric strip from both sides closely at its folded edge, cutting the trailing end of the fabric strip and depositing the thus cut fabric strip upon and in registry with a stack of previously accumulated fabric strips. An apparatus is also disclosed for carrying this method into practice, which essentially comprises a gate means having a guide slit through which a slide fastener chain is passed, a gripper means releasably gripping a leading end of the fastener chain, and a clamping means releasably clamping the fabric strip from both sides closely adjacent at the fastener chain.

A slider holding apparatus includes a slider holder for holding thereon a slider, and orientating means for angularly moving the slider holder on its vertical axis to adjust the orientation of the slider held on the slider holder.

A discharge device incorporated in an elongate article processing apparatus includes a discharge unit disposed immediately downstream of a cutter of the apparatus and a conveyor unit extending downstream of the discharge unit. The discharge unit includes a drive roller and a vertically movable pinch roller, the pinch roller being held in its upper standby position remote from the drive roller while the cutter is in operation. The conveyor unit includes a presser roller vertically movable, in independent of the movement of the pinch roller, into and out of engagement with a belt conveyor of the discharge unit.

A method of feeding a continuous slide fastener chain with successive fly strips in a slide-fastener finishing machine, comprises feeding the slide fastener chain with successive fly strips along a horizontal straight path normally by applying driving force to one tape free of the fly strips, and feeding the slide fastener chain by applying the driving force to both of the opposed tapes while the slide fastener chain is threaded through a slider. An apparatus for carrying out this method comprises a main roller engageable with the lower surfaces of the opposed tapes, and first and second associate rollers engageable with the respective upper surfaces of the opposed tapes and vertically movable independently of each other.

In a method and apparatus for applying a protective strip by sewing to an end of a slide fastener, a continuous protective strip is fed downwardly toward a tape supply position on the base of a sewing machine with its one surface facing opposite to a direction of feed of a slide fastener until a leading end portion of the protective tape overlays the base by a predetermined length, then the leading end portion is bent in a direction opposite to the fastener feed direction by a stream of pressurized air issued from an air nozzle, thereafter, a slide fastener is advanced along the base until its leading end reaches to a sewing position located downstream of the tape supply position, thereby causing the leading end portion of the protective tape to bend into a U-shape extending from the back to the face of the slide fastener around the leading end thereof, then the U-shaped leading end portion is cut from the continuous protective tape, thereby forming a U-shaped protective strip which in turn is sewn to the leading end of the slide fastener.

Method and apparatus for applying protective strip to end of slide

An apparatus for holding a slider includes a holder body defining a space for receiving a pull tab, and a slider support having a first seat and a bore below the first seat. A locking lever is pivotally disposed in the space and has a locking projection. A supporting arm is angularly movable between an inclined position in which its second seat is positioned remotely from the first seat and it presses the locking lever so that the projection is retracted into the bore, and an upright position in which the second seat is positioned adjacent to the first seat. As the arm is angularly moved from the inclined position to the upright position, the locking lever is allowed to turn so that the projection projects through the bore for engagement with the slider's pull tab.

An apparatus automatically manufactures a succession of slide fasteners with flies from a continuous slide fastener chain having a pair of intermeshed rows of coupling elements with element-free spaces therein and stringer tapes supporting the rows of coupling elements, respectively, with the flies sewn to one of the tapes. The apparatus includes a feed path along which the chain can be fed, a feed roller assembly for feeding the chain along the feed path in selective engagement with the intermeshed rows of coupling elements, and an element guide operatively coupled with the feed roller assembly for guiding the rows of coupling elements along the feed path across the feed roller assembly. The feed roller assembly comprises a driven roller and an idling roller movable toward and away from the driven roller for feeding the chain along the feed path. The element guide has guide legs disposed upstream and downstream of the feed roller assembly and having guide grooves, respectively, aligned with the feed path. The element guide is angularly movable and is normally urged into an angular position to cause one of the guide legs to guide the rows of coupling elements in the guide groove therein while allowing the mounted slider to move past the other guide leg.
