ABSTRACT:
A coupling-element pairing apparatus includes a substantially Y-shaped guide channel defined in a base and including a joint passage for interengaging disengaged rows of continuous filamentary zigzag coupling elements. The joint passage has a width narrow enough to substantially prevent interengaged rows of coupling elements from moving laterally with respect to one another. A pair of toothed guide wheels disposed one on each side of the joint passage for guidingly advancing the interengaged rows of coupling elements through the guide channel. Each guide wheel has a plurality of peripheral teeth, two adjacent ones of which project into the joint passage for holding therebetween one of the connecting portions of each row of coupling elements at opposite ends thereof without impairing the coupling elements.
