Abstract
In the fastener-chain-finishing apparatus, only a knockout among plural members arranged below a fastener-chain-transfer path of a space-forming unit can move up and down but all the other members are not movable. Consequently, the units below the chain-transfer path can be compact. Further, main bodies of movable grippers and a punch of the space-forming unit, which have a length equal to a space-forming length of the fastener chain and are arranged above the chain-transfer path, have end surfaces that are exposed outside and are flush with each other at least on a side of a stopper-attaching unit arranged adjacent to them. As a result, all the operating members of the space-forming unit can be arranged so as to contact with the stopper-attaching members of the stopper-attaching unit. Therefore, it is possible to form a space on the slide fastener chain to which particularly coil-shaped continuous coupling elements are attached by sewing thread, simultaneously with attachment of the stopper, which was conventionally impossible to achieve.
