<p>A coupling-element pairing apparatus (10) includes a substantially Y-shaped guide channel (12) defined in a base (11) and including a joint passage (21) for interengaging disengaged rows of continuous filamentary zigzag coupling elements (13,14). The joint passage (21) has a width narrow enough to substantially prevent interengaged rows of coupling elements (13, 14) from moving laterally with respect to one another. A pair of toothed guide wheels (22, 23) disposed one on each side of the joint passage (21) for guidingly advancing the interengaged rows of coupling elements through the guide channel (12). Each guide wheel (22, 23) has a plurality of peripheral teeth (24), two adjacent ones (24a, 24b) of which project into the joint passage (21) for holding therebetween one of connecting portions (18) of each row of coupling elements (13, 14) at opposite ends thereof without impairing the coupling elements (13, 14).</p> |
