Abstract
Each revolving ring of a continuous-spinning frame for textile yarn is mounted on a fluid bearing and driven in rotation by a ring traveler. The resisting torque of the ring is intentionally increased by means of hollow or projecting portions such as fins formed on the ring in order to produce a difference in speed between the normal speed of rotation of the spindle and the speed of rotation of the ring. The result thereby achieved is to ensure uniform tension of the yarn and to improve operating stability of the spinning frame.
