Apparatus for attaching top end stops to a continuous slide fastener chain.

摘要

A clamping mechanism (11) mounted on a punch/die holder (13) includes a pair of punch arms (12) angularly movably supported on the punch/die holder (13) and a die (14) fixed to the punch/die holder (13) and disposed between the punch arms (12) for supporting U-shaped top end stops (40) between the die (14) and lower ends of the punch arms (12). The punch arms (12) are angularly moved to cause the lower ends thereof to clinch the top end stops (40) respectively about the beaded marginal edges (71) of slide fastener stringer tapes (70) at one of element-free spaces (73) adjacent to ends of two rows of coupling elements (72). The die (14) and the lower ends of the punch arms (12) have slanted surfaces (45, 46) for smoothly guiding the beaded marginal edges (71) into the top end stops (40) between the die (14) and the punch arms (12). The beaded marginal edges (71) of the stringer tapes (70) at the element-free space (73) are separately directed toward the top end stops (40) supported between the die (14) and the lower ends of the punch arms (12).
