ABSTRACT:
An apparatus for interengaging a pair of rows of slide fastener coupling elements on a pair of stringer tapes, respectively, with a pair of top end stops mounted on the stringer tapes respectively at confronting ends of the rows of coupling elements, includes a base and a pairing guide mounted on the base and normally defining a substantially Y-shaped guide channel including a pair of branched guide passages for receiving disengaged rows of coupling elements, respectively, and a joint passage for discharging interengaged rows of coupling elements. The pairing guide comprises first guide means fixed to the base and including first flange means defining the branched guide passages, and second guide means movably supported on the base and including second flange means normally defining the joint passage. The Y-shaped guide channel is thus normally defined jointly by the first and second flange means. The second flange means is retractable away from the first flange means in response to the engagement of at least one of the top end stops with the second flange means, whereby the top end stops can be discharged out of the pairing guide.
