ABSTRACT:
An apparatus for manufacturing a continuous slide fastener stringer including a row of injection-molded coupling elements secured to a stringer tape along a longitudinal edge thereof, includes a pair of fixed and movable mold members through which the stringer tape is fed by a tape advancing means, and a pair of upper and lower tape shifters mounted on the movable mold member for moving the stringer tape between a first position in which a part or portion of the stringer tape lies flatwise on a mold surface of the movable mold member and a second position in which the tape's part is spaced from the mold surface and held out of interference with a feeler projecting from the mold surface of the movable mold member. During the advancing movement of the movable mold member toward the fixed mold and in timed relation to the stringer-tape advancing means, the tape shifters are movable with respect to the movable mold member to place the tape's part in the first position.
