Abstract
A ring for use in spinning machinery such as ring spinning machines and twisting machines, which is usable at a high spindle revolutionary speeds of 20,000 r.p.m. The ring comprises a ring flange, a neck part, a collar and a trunk part. The trunk part has a ring fitting part and is provided, at the surface which contacts at least the ring traveller, with a composite plated layer of nickel and phosphorous alloy containing hard fine grains. The ring is further treated with heating and polishing processes to increase hardness and smoothness of the surface to thereby improve anti-wearing properties and heat-resistance properties.
