Abstract
A system for bonding alternate S and Z twist plied yarn. The system bonds the plied yarns as they move in a path through the process and permits balanced expansion of the yarn while preventing lateral movement out of the path. The bonding of the yarn strands while plied together, forms a bond characterized by a dense region of filaments adhesively joined together where one of the strands overlaps another strand, followed by a less dense region along the one strand where fewer filaments are adhesively joined, followed by another dense region.
