5461/0005 RGY SELF TWIST YARN AND METHOD AND APPARATUS FOR MAKING SUCH YARNS Abstract of the Disclosure Self-twisted yarns are made by a system in which a strand twisting device is engaged with the strand and moves at strand speed to twist the oppositely-extending sections of the strand in opposite directions. The strand is brought together with another strand and released, enabling it to untwist and twist itself to the other strand. Various arrangements are disclosed for maximizing the distance between twist reversal nodes, for cabling plied yarns together, for strengthening the strands, for reducing the tensile stresses imposed on the strands and for producing unique products with non-uniform node spacing or unequal strand lengths between adjacent pairs of nodes.
