Abstract:
A spinning ring for winding a yarn fed from a yarn feeder on a bobbin, comprising:a stationary ring mounted on a base member;a rotary ring disposed inside and concentrically with the stationary ring for rotation about the central axis thereof, the bobbin being disposed inside and concentrically with the rotary ring for rotation about the central axis thereof;a traveler disposed on the rotary ring for revolution in the circumferential direction of the rotary ring to guide the yarn fed from the yarn feeder with respect to the bobbin;the rotary ring being supported on the stationary ring by means of a slide ring; anda brake for applying a braking force to the rotary ring in response to the rotational speed of the rotary ring, the braking force of the brake and a frictional force between the rotary ring and the slide ring being determined such that, when the bobbin rotates at a normal operating speed, the rotational speed of the rotary ring is lower than the rotational speed of the bobbin and the rotary ring rotates substantially in the unison with the traveler so as to maintain the same rotational speed as the traveler and prevent over-run rotation.
