摘要： A spinning ring structure (10) for twisting a fleece into a yarn and taking up the yarn on a bobbin (82) comprises a stationary ring (20) fixedly mounted on a ring rail (74), a rotary ring (30) disposed for rotation about its own axis inside the stationary ring (20) coaxially therewith so as to surround the bobbin (82) disposed with the stationary ring (30). A traveler (50) is put on the rotary ring (30) so as to revolve along the circumference of the rotary ring, and a brake ring (60) is mounted on the rotary ring (30) and provided with a plurality of radial vanes (68) to which air applies resistance against the turning of the brake ring. The brake ring (60) is provided with an air pressure evading wall (64) for avoiding the influence of a pressure generated by whirling air currents produced by the rotating cop, on the brake ring (60) to prevent retardation of the variation of the rotational speed of the rotary ring according to the variation of the effective circumferential speed of the cop built on the bobbin during a cop building operation so that a balloon formed by the yarn will not expand and will not collapse.
