  • Spinning device comprising a ring rotatably supported on a fluid bearing
    Patent number: 4244170
    Abstract: Each spinning ring of a ring-frame spinning device is carried by a fluid bearing supplied with compressed air for centering and lifting the ring. The flow of compressed air is selectively interrupted or at least reduced by means of an automatic or hand-operated valve or cock in order to reduce or suppress the ring-lifting action. A braking action is thus produced on the ring as it is brought into frictional contact with a top horizontal radial surface of a ring carrier or stator. The braking action can be applied selectively to one or a number or all the rings of any ring spinning frame employed in the textile industry.
