Abstract
A spinning ring for winding a yarn fed from a raw yarn bobbin on a bobbin includes a stationary ring that is mounted on a ring rail. A rotary ring is disposed inside and concentrically with the stationary ring for rotation about the central axis thereof. The bobbin is disposed inside and concentrically with the rotary ring for rotation about the central axis thereof. A traveler is disposed on the rotary ring for revolution in the circumferential direction of the rotary ring to guide the yarn fed from the supply bobbin with respect to the bobbin. When the bobbin is rotated substantially at normal operating speed, the speed of the traveler and the rotary ring are rotated substantially in unison with each other relative to the stationary ring.
