<p>A slide fastener chain (13) with reinforcing strips (39) is fed along a feed path (12) through a finishing apparatus (10) for ramming the reinforcing strips (39). The finishing apparatus (10) has a chain guide unit (14), a cutter unit (15), and a chain tensioner unit (16). The chain guide unit (14) includes a stop (43) having recesses (55, 56) for accommodating some coupling elements (37) and steps (57) for engaging endmost coupling elements (63). The chain tensioner unit (16) has a presser gripper (114) for pressing the slide fastener chain (13) against a support base (116) and a presser roller (119) for depressing the slide fastener chain (13) to tension the same for thereby forcibly pushing the endmost coupling elements (53) against the steps (57). When the slide fastener chain (13) is tensioned by the chain tensioner unit (16), one of the reinforcing strips (39) is accurately positioned with respect to the cutter unit (15). The reinforcing strip (39) is now trimmed by central and side cutters (71, 74, 75) which cut off central and side excessive portions (41, 104, 105) completely.</p> |
