ABSTRACT:
On a ring spinning or twisting frame having winding units with rotatable thread follower rings, the difference in the speed of rotation between the ring and its follower during the restarting of the winding unit, after repair of a thread break, is maintained within acceptable limits while the frame continues to run at its high operational speed, by controlling the rotational speed of either the ring or the spindle, the speed of the controlled element being varied either continuously, or in one or more steps during the restarting operation.
