Method and apparatus for manufacturing concealed woven slide fastener stringer

摘要

An apparatus for manufacturing a concealed woven slide fastener stringer comprises a frame (16) disposed at a side where foundation warp yarns (8) of a fastener tape (3) are to be arranged and having core-cord-inserting holes (19); a mandrel (17) projecting from the frame (16) for shaping a thermoplastic resin monofilament (21) into a fastener element (2); an anchoring-weft-yarn carrier bar (29) and a foundation-weft-yarn carrier bar (28) both disposed downwardly of the mandrel (17); a rotor (20) revolvable about the frame (16) and having a monofilament guide hole (22); an anchoring-warp-yarn heddle (25) disposed above core cords (7); a foundation-warp-yarn heddle (24) disposed below the core cords (7); and a hook lever (26) vertically movably disposed before the foundation-weft-yarn carrier bar (28) for pushing the outer core cords (7) downwardly.
