Abstract (en)
[origin: EP3910097A1] A ring (11) of a spinning machine includes a sliding surface on which a traveler (12) slides, wherein the spinning machine is configured to wind a yarn (Y) through the traveler (12). The sliding surface has a texture having a plurality of recesses and a plurality of projections. Each projection has a curved shape and is located between adjacent recesses. The projection has a curvature radius of 40 to 400 µm. A method for manufacturing the ring (11) includes a step for forming the sliding surface. The step for forming the sliding surface includes: a first step for forming a plurality of dimples in a surface of the ring (11); and a second step for rounding a peripheral edge of each dimple and/or a portion between adjacent dimples.
