<p>In an apparatus for forming a row of zigzag coupling elements, a winding unit includes a guide plate having a guide hole through which a monofilament is supplied onto a periphery of a continuously rotating die wheel. The guide plate is driven by two separate drive mechanisms, for lateral reciprocating movement and tangential reciprocating movement, respectively, with respect to the die wheel periphery so that the guide hole traces a horizontal figure-eight curve to thereby wind the monofilament alternately around a pair of rows of circumferentially staggered pins, on the die wheel periphery.</p> |
