ABSTRACT:
An apparatus automatically manufactures a succession of slide fasteners with flies from a continuous slide fastener chain having a pair of intermeshed rows of coupling elements with element-free spaces therein and stringer tapes supporting the rows of coupling elements, respectively, with the flies sewn to one of the tapes. The apparatus includes a feed path along which the chain can be fed along, a fly folder in the feed path for folding one of the flies on itself at a time, a slider applicator in the feed path for mounting one of the sliders at a time on the rows of coupling elements, a feed roller assembly for feeding the chain along the feed path in selective engagement with the intermeshed rows of coupling elements, a bottom stop applicator and chain cutter in the feed path for applying a bottom stop to the rows of coupling elements and cutting off the chain across one of the element-free spaces to produce a slide fastener with a fly, and a discharge roller assembly actuatable in synchronism with the feed roller assembly for discharging the assembled slide fastener with the fly.
