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.
