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.
Claims8
A spinning or twisting device comprising an annular support, a rotary ring, a fluid bearing arranged on said annular support for supporting said rotary ring for rotation, and a traveler slidably engaged on said rotary ring and effecting rotation of said ring, wherein controlling means are provided for obtaining a predetermined differential rotational speed between said rotary ring and said traveler.
