RING-TRAVELLER SYSTEM FOR SPINNING AND TWISTING FRAMES AND METHOD OF TREATMENT OF TING SURFACE IN RING-TRAVELLER SYSTEM FOR SPINNING AND TWISTING FRAMES

FIELD: ring-traveller systems used in spinning and twisting frames. SUBSTANCE: ring surface at least in zone engageable with traveller is made of polycrystalline ceramics. In this case, surface structure of ceramic coating is made with rounded boundaries of grains forming space for reception of self-forming lubricating layer from fibers. Traveller is made of flexible carrying material and has metal and/or ceramic surface whose hardness equals to that of ceramic surface of ring or exceeds it. method of ring surface treatment in ring-traveller system includes procedures of deposition of ceramic coating and finishing by making surface structure with rounded boundaries of grains. EFFECT: prolonged service life of ring-traveller system; high productivity without reducing thread quality; increased profitability. 10 cl, 1 dwg
