ABSTRACT:
An apparatus for making alternate S and Z twist plied yarn from individual singles yarns. The apparatus twists the singles yarns as they move in a path through the process, twisting the individual yarns in either an S or Z direction. The bonding of the ply-twisted yarns at a node while applying twist 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.
