In a ring-traveler system of a ring spinning machine, circular recesses (15) are formed on a sliding surface of a ring (11) on which a traveler (12) slides when the traveler travels. The depth of each recess is 0.5 to 8 µm, the diameter of each recess is 5 to 30 µm, and the percentage of the area of all recesses in the area of the entire sliding surface of the ring is 5 to 16%. |
