Abstract: A cord stopper comprises a double-headed plug having a pair of through holes formed one through each plug heads perpendicularly to the longitudinal axis thereof; a pair of sockets each reciprocally fitted over the respective plug head and having a pair of apertures formed through the periphery thereof; and a pair of springs for normally urging the sockets away from each other. When the sockets are fully compressed against the bias of the spring, the apertures come into registry with the respective through holes for letting a string through.

Abstract: A retainer assembly for retaining cords, strings or the like in position comprises a cylindrical tube having holes, a resilient locking means mounted in the tube and a pair of end taps and having a through bore. The locking means has arcuately inwardly bent upper and lower wing members defining therebetween slits. The end taps each have an arrow-headed portion adapted to be received through and locked inside of the slit of the locking means and a tapered portion resiliently engageable in the slit and movable between the upper and lower wing members to bring the bore into and out of registry with the holes.

Abstract: A strap retainer includes a flexible plate adapted to be attached by sewing to a substrate, and a retaining mound integral with the plate and raised above the upper surface of the plate so as to define therebetween a pair of laterally aligned apertures for the passage therethrough of the strap. A sewing groove extends in the upper surface of the plate along a peripheral edge of the plate for receiving a sewing thread. A support ridge projects from the bottom surface of the plate and extends along the peripheral edge of the plate, the ridge being disposed inwardly of and immediately adjacent to the sewing groove. The strap retainer thus constructed is free from curling up around the periphery thereof and is capable of protecting the sewing thread against abrasive wear.

Abstract: An apparatus for manufacturing a continuous slide fastener stringer, including a plurality of longitudinally spaced rows of injection-molded coupling elements secured to a stringer tape 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 disposed on one of a pair of relatively movable mold members adjacent to a leading mold cavity therein for detecting a trailing end of the injection-molded coupling elements, and a movable feeler disposed on the one mold member downstream of the fixed feeler at a distance substantially equal to the length of the element-free portions of the stringer. The movable feeler is driven by a driving mechanism to selectively project or retract from a mold surface of the one mold member in interlocking relation with a feed mechanism which intermittently feeds the stringer tape by a predetermined distance.
