Abstract
A rotator for a twister for twisting yarn at more than two double twists for each rotation is provided. The rotator includes a rotating member, a stationary member and a tubular rod coupled together. Between a center rod and a point in an L-shaped passageway in the rotator and a bending point at a small guide wheel is produced respectively double twists to the yarn. A rectangular frame of the rotator member rotates with the rotator member so as to force the portion of yarn between a top hole in the frame and the bending corner of the L-shaped passageway to produce more double twists. Thus, at least two double twists are produced for each rotation of the rotator member to increase the speed of twisting yarn.
