摘要:
A punch blade (72; 80) depresses the coupling heads (79) of a length of successive filamentary coupling elements (76) toward a knockout blade (39) while sandwiching stringer tapes (43, 44) between upper and lower grippers (55, 56, 21, 22). The punch blade (72; 80) is lowered until lower legs (78) of the coupling elements (76) are cut off by cutter blades (31,32). The punch blade (72; 80) and the knockout blade (39) are then lifted while gripping the severed coupling elements (76) therebetween to forcibly remove the coupling elements (76) out of engagement with sewing thereads (77) on the stringer tapes (43, 44). The upper grippers (55, 56) have confronting steps (61, 62) for engaging the sewing threads (77) so that the severed coupling elements (76) can be detached reliably and smoothly from the stringer tgapes (43, 44) without unduly tensioning the sewing threads (77) and stringertapes (43,44). The punch blade (80) may have a vertical reinforcement member attached to at least one side edge thereof and having a lower tooth (86) projecting downwardly beyond a lower edge (84) is pressed against the coupling elements (76), the lower tooth (86) enters between adjacent coupling elements (76) to position the coupling elements (76) against unwanted longitudinal displacement with respect to the punch blade (80).
