Abstract
A method and apparatus for forming a loop-shaped substrate composed solely of helical wound yarns. An endless winding belt is mounted on a pair of support rolls for travel in an endless path and a plurality of yarns are connected in parallel spaced relation to a threading section disposed along a side edge of the belt. As the belt is driven in its endless path, the yarns are wound on the rolls in a helical pattern. Guide members are located adjacent and upstream each of the rolls and include a plurality of openings to receive and uniformly space the respective yarns. After the group of yarns has been wound in a single convolution, the wound convolution is shifted laterally along the length of the rolls to thereby enable subsequent convolutions of the yarns to be wound on said rolls.
