摘要： Spinning machine includes draft rollers 3, 4 and 5 and a drive device for driving the draft rollers. The drive device has a drive unit 6 for driving the front draft roller 5, and a drive unit 7 for driving the back and middle draft rollers 3 and 4. Each drive unit has a variable speed motor M2 or M3 and a transmission mechanism, and the variable speed motor of the drive unit 6 for driving the front draft roller 5 is a synchronous AC motor having permanent magnets. A reverse rotation preventing device including a ratchet wheel and a pawl is arranged in the drive unit 6 for preventing a reverse rotation of the front draft roller 5, occurring with a reverse rotation of the synchronous motor M2, caused by the action of the permanent magnets in the synchronous motor upon starting the synchronous motor.

摘要： A rotary spinning ring structure for use on a spinning frame or the like comprises, as principal components, a stationary tube (22) fixedly supported on a ring rail (7), a slide ring (25), a rotating tube assembly (26) 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 (26) comprises a rotating tubular body (28) made of an antistatic synthetic resin material, a circular brake ring (36) made of an antistatic synthetic resin material and joined to the rotating tubular body (28), and a dust cover (30) 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.
