  • Spinning ring for a ring spinning machine and method of manufacturing thereof
    Patent number: 6568164
    Abstract: A spinning ring, in which a ring flange portion 101 making a track permitting a ring traveller to run thereon is divided into an inner flange 103 and an outer flange 106, the inner flange 103 is continuously formed from a sheet steel, the outer flange is formed together and integral with a ring neck portion 109 and a mount portion 102 by cutting, the inner flange 103 and the outer flange 106 are secured to each other by a securing means, and a ring flange portion 101 is provided in an upper portion of the spinning ring 100. The spinning ring enables enhancing the ring flange portion in accuracy and wear resistance, and preventing fine vibrations of the ring flange portion from causing abnormal wear of and shortening of service life of a ring traveller and the ring flange portion and frequent yarn breakage leading to reduction in productivity and falling-off of the ring flange portion due to shock.
