Title: Rotating ring for spinning
Inventor: KAGOHASHI TOSHINORI
IPC: D01H7/56
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To provide the subject rotating ring secured in air braking effect thereon through controlling the air stream blown from an annular brake section. SOLUTION: When a rotating cylinder 26 is rotated by spinning rotation, as the outer periphery of each of fins F corresponding to brake rings 36 exposed downward from the lower end of a fixed cylinder 22 is situated in an open space with a sufficient distance from the tapered air stream guide face 73 of a turning cover 70, the air stream going out radially due to the rotation of the fins F is guided slantly downward owing to the air stream guide face 73 without springing back, therefore, being neither affected by an air stream blown by the fin F itself nor acting on the fin F of the adjacent rotating ring 20, thus the fin F produces a moderate rotary brake force by the aid of the air frictional resistance between the fin F and air.
