PURPOSE: False twisting is applied to the twisted yarn taken out of the rotor, as a force of opposite direction to the yarn-running is applied to the twisted yarn to ensure the yarn to be held in the yarn-collecting part at the top of the twisting yarn in the rotor.
CONSTITUTION: The diameter of the yarn-guiding hole 39 is formed larger on the inlet side 40, smaller on the outlet side and a step 42, between them. An air- jetting nozzle 43 is opened at the larger diameter part 40 so that the hole is inclined tangentially to the inner surface of the larger diameter hole 40 on the axis of the hole toward the stepped part. The fluid flow can positively whirl so that it can press the twisted yarn toward the stepped part and no unreasonable, force is applied to the twisted yarn in the taking-up direction.
