ABSTRACT:
Disclosed is an improved ring and traveller system for spinning and twisting frames. At least the surface of the ring coming into contact with the traveller consists of a polycrystalline ceramic material and the ceramic surface of the ring has a surface structure with rounded grain boundaries which form a storage volume for a self-generating lubricating film of fibers. The traveller consists of a resilient carrier material, especially metal, and has a metal and/or ceramic surface, the hardness of which is greater than the hardness of the ceramic surface of the ring.
