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 o

Abstract: In an improved rotary ring winding device wherein a rotary ring member is rotatably supported by a bearing device secured to a ring rail, the bearing device is provided with a first annular magnetic member wherein an annular recess is formed. The rotary ring member is provided with a second annular magnetic member having an annular projected portion which is arranged in the annular recess of the first annular magnetic member with an air-gap therebetween. The first annular magnetic member is provided with at least an annular portion formed by an electric magnet, and the other portion of the first annular magnetic member and the second annular portion are formed by permanent magnets, wherein each annular portion of the first magnetic member and each annular portion of the second magnetic member, facing each other, are designed to have identical magnetic poles.

Abstract: A rotary ring spinning device in combination with a spindle, and utilized for a ring spinning machine provided with ring rail lifting mechanism, comprises a holder for rigidly mounting a rotary ring spinning device to the ring rail, a rotary ring body rotatably mounted on the holder via a bearing, and an inner motor disposed in an annular space formed between the rotary ring body and the holder coaxially thereto.
