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, a feed roller assembly for feeding the chain along the feed path in selective engagement with the intermeshed rows of coupling elements, and an element guide operatively coupled with the feed roller assembly for guiding the rows of coupling elements along the feed path across the feed roller assembly. The feed roller assembly comprises a driven roller and an idling roller movable toward and away from the driven roller for feeding the chain along the feed path. The element guide has guide legs disposed upstream and downstream of the feed roller assembly and having guide grooves, respectively, aligned with the feed path. The element guide is angularly movable and is normally urged into an angular position to cause one of the guide legs to guide the rows of coupling elements in the guide groove therein while allowing the mounted slider to move past the other guide leg.
