A parts feeding apparatus is disclosed for use in feeding a supply of garment appliance parts such as buttons, hooks, slide fastener component parts and the like from parts reservoirs or parts feeders through a plurality of feed chutes onto a parts applying holder. The feed chutes each carrying thereon an array of parts of different types and colors are pivotally movable in the same plane into and out of an operative position relative to the parts applying holder, in which position the parts are selectively transferred onto the holder.

An apparatus for attaching bottom stops of a generally H-shaped cross section to a slide fastener chain. According to a preferred embodiment, a pair of stringer tapes of one of successive spaced element-free space sections are spread apart by a spreading member. The top and bottom faces of the center base of the bottom stop are clamped resiliently by clamping members until attaching of the bottom stop to the fastener chain is finished and the clamping members move vertically for placing the bottom stop between the stringer tapes of the space section. The spread pair of stringer tapes are then drawn near to come toward each other by a drawing member until the beaded edges of the space section can be threaded respectively through spaces formed between the pair of gripping legs of the bottom stop. Then the fastener chain is transported so that the bottom stop is located to be contacted with the space section-side face of the terminal element of the row of coupling elements. Finally, the gripping legs of the bottom stop are bent with a punch and a die for attaching the bottom stop to the fastener chain. In the present invention, since clamping operation is carried out so as not to interfere with the bending operation, the bottom stop can be attached to the slide fastener chain surely and precisely.

A coupling element shaper comprises a pair of parallel externally threaded screw members corotatable in a common direction and disposed on opposite sides of a mandrel along which a core thread is fed while a filamentary material is wound around the mandrel into a row of helically coiled coupling elements. Each screw member has a portion varying in pitch to gradually reduce in a direction from one end to the opposite end thereof. The core thread is squeezed by the coupling elements as shaped by such portion so as to have a certain degree of stretchability which can cancel or take out its shrinkage when the coupling elements are sewn to a slide fastener stringer tape.

A stamping apparatus disclosed deforms a filamentary material to provide coupling heads and the like at predetermined intervals along the length of the filament which is to be coiled and attached to stringer tapes for a slide fastener. The apparatus includes a pair of stamping rolls which are rotatable in opposite directions on their own axes simultaneously as they orbit about the axis of a rotor. A ring member rotatably connected to the stamping rolls is driven via the same power source as the rotor but rotates at a slower or faster angular speed than the rotor, the resulting angular speed differential being utilized to effect the rotation of the stamping rolls on their axes.

Improvements in apparatus of the type including a mandrel around which a continuous filament is coiled and which has a guide channel formed longitudinally therein for slidably receiving a continuous core to be positioned within the coil, and a mandrel holder holding the mandrel adjacent one end thereof and reciprocating with the latter in the longitudinal direction thereof in step with the formation of each convolution of the coil. A unit length of the core required for each coil convolution is forcibly pulled away from a core pay-off bobbin by a pair of pull-out rolls actuated intermittently by a ratchet mechanism. The mandrel holder has formed therein passageways through which the core travels from the pull-out roll pair to the entrance end of the guide channel in the mandrel. The passageways are adapted to provide several obtuse-angled bends for holding the core in frictional contact with the mandrel holder, so that the successive unit core lengths are delivered without tension to the guide channel in the mandrel with the reciprocation of the mandrel holder.
