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.

A strap retainer (l0) includes a fexible plate (l0) adapted to be attached by sewing to a substrate (l6), and a retaining mound (ll) integral with the plate (l0) and raised above the upper surface of the plate so as to define therebetween a pair of laterally aligned apertures (l2) for the passage therethrough of the strap (l3). A sewing groove (l4) extends in the upper surface of the plate (l0) along a peripheral edge of the plate for receiving a sewing thread (l5). A support ridge (l9 a ) projects from the bottom surface of the plate (l0) and extends along the peripheral edge of the plate, the ridge being disposed inwardly of and immediately adjacent to the sewing groove (l4). The strap retainer (l0) thus constructed is free from curling up around the periphery thereof and is capable of protecting the sewing thread (l5) against abrasive wear.

摘要:
Disclosed herein is a buckle comprising a buckle body (1) and a movable member (15). The movable member (15) is pivotally mounted on the buckle body (1) so that the movable member (15) can be rotated to a working position wherein it is folded on the buckle body. The movable member (15) has an engaging projection (19) which penetrates into an engaging opening (4) fomed in the buckle body so that a belt (8) is clamped between the engaging projection and the buckle body when the movable member is in the working position. A locking device (19), (6) is provided on the movable member and the buckle body to hold the movable member in the working position.
