Ring‑traveler unit for ring spinning machines

Abstract

A ring-traveler device with no liquid lubrication of a ring type spinning machine includes a ring 11 and a traveler 12 that is slidable along the ring. The ring-traveler device has a plurality of first recesses 15 and a plurality of second recesses 16 formed in at least one of sliding surfaces of the ring and the traveler. Each first recess has a width between 10 and 100 µm and is formed by an opening edge 15A and an inner surface 15B, Each second recess 16 has a width smaller than each first recess 15. At least one of the second recesses extends across at least one of the opening edges and the inner surfaces of the first recesses.

Description

technical field [0001] The present invention relates to a ring-traveler system in a ring spinning machine, more particularly to a ring-traveler system without liquid lubrication. Background technique [0002] In the ring-traveler system of ring spinning machines and ring twisting machines, different methods have been proposed to protect the ring-traveler system from deterioration caused by frictional wear and seizure, e.g. by using different materials, surfaces Handling, shape changes and the use of liquid lubrication, thereby increasing the operating speed and prolonging the service life of the ring-traveler system. The use of liquid lubrication in ring-traveler systems is relatively cheap and effective, but is limited to wool spinning because it can contaminate the yarn with oil and is not easy to maintain. [0003] Japanese Patent Application Publication No. 2014-29045 discloses a ring-traveler system for a ring spinning machine in which grooves with a depth between 0.1 ...
