Abstract (en)
[origin: WO8602113A1] A ring for spinning machines, such as a spinning frame and a yarn twisting machine. This ring consists of a flange portion, a neck portion, and a trunk portion having a ring rail-fitting section. At least the portion of the ring which slidingly contacts a traveler is formed of a ceramic material, or it is covered at its outer surface with a layer of a ceramic coating. Thus, a ring for spinning machines, which has an outer surface of a high strength, a high smoothness like the smoothness of a mirror surface, and improved wear-resistance, thermal resistance and corrosion-resistance, is obtained. This ring enables a spinning machine to be operated at a high speed of not less than 20000 r.p.m.
