ABSTRACT:
An apparatus for mating a pair of slide fastener coupling elements carried on a pair of stringer tapes, respectively, includes a pair of guide wheels each having a plurality of peripheral teeth meshable with one of unengaged rows of coupling elements for guiding the same and for regulating distances between adjacent coupling elements of each row, and a pair of presser rollers for squeezing the unengaged rows of coupling elements to interengage the same immediately after the latter are released from the teeth of the guide wheels. The axis of each guide wheel is eccentric to that of one of the presser rollers. With this arrangement, the pair of rows of coupling elements can be mated nicely without obstruction or impairment by wheel teeth but while such regulated distances between adjacent coupling elements of each row remain.
