ABSTRACT:
A process and apparatus for making alternate S and Z twist plied yarn from individual singles yarns includes the steps of tensioning the singles yarns as they move in a path through the process, twisting the individual yarns in either an S or Z direction, snubbing the yarn to restrain ply twisting so the twist in the singles yarn can equalize itself, stopping the forward movement of the yarn, then bonding the ply-twisted yarns at a node while applying twist, stopping the twisting operation, then repeating the procedure while twisting in the opposite direction. The ply twisted yarn has a lower defect level of less than 2.5 defects per 100 inch length of yarn.
