ABSTRACT OF THE DISCLOSURE A slide fastener chain with reinforcing strips is fed along a feed path through a finishing apparatus for trimming the reinforcing strips. The finishing apparatus has a chain guide unit, a cutter unit, and a chain tensioner unit. The chain guide unit includes a stop having recesses for accommodating some coupling elements and steps for engaging endmost coupling elements. The chain tensioner unit has a presser gripper for pressing the slide fastener chain against a support base and a presser roller for depressing the slide fastener chain to tension the same for thereby forcibly pushing the endmost coupling elements against the steps. When the slide fastener chain is tensioned by the chain tensioner unit, one of the reinforcing strips is accurately positioned with respect to the cutter unit. The reinforcing strip is now trimmed by central and side cutters which cut off central and side excessive portions completely.
