ABSTRACT:
A rotary ring for spinning including a holder having a lower end face, a ring-shaped rotary member supported rotatably by a bearing inside the holder, a braking shoe carried by a lower end of the rotary member and having an upper portion fixed to the lower end of the rotary member, the braking shoe having a lower portion for extending radially outwardly from the upper portion in a conical shape, the lower portion having an inner face and an outer face, the braking shoe being of a flexibility and shape such that when the rotary member is rotated, the lower portion of the braking shoe will extend radially outwardly to a greater degree due to centrifugal force so that the lower portion will be moved in a space beneath the lower end face of the holder and generally toward the lower end face, a substantially annularly shaped non-magnetic braking runner positioned to be in contact with the outer face of the lower portion of the braking shoe, the non-magnetic braking runner being mounted so as to be carried by the outer face of the braking shoe to frictionally contact the lower end face of the holder and to exert a braking force thereon.
