Abstract
A rotary spinning ring structure for use on a spinning frame or the like comprises, as principal components, a stationary tube fixedly supported on a ring rail, a slide ring, a rotating tube assembly supported for rotation by the slide ring on the stationary tube, and a balancing mechanism incorporated into the rotating tube assembly. The rotating tube assembly comprises a rotating tubular body made of an antistatic synthetic resin material, a circular brake ring made of an antistatic synthetic resin material and joined to the rotating tubular body, and a dust cover made of an antistatic synthetic resin material and put on a middle portion of the rotating tubular body. Each of the antistatic synthetic resin materials forming the rotating tubular body, the brake ring and the dust cover is a mixture of a synthetic resin, and fibers, powder or flakes of a conductive material, such as carbon and has a low volume resistivity.
