the invention relates to a refrigerating - lubricating cursor ring that can be used in ring twisting machines , continuous ring spinning machines and double twisting machines . said ring serves as a guide for a cursor and comprises a cylindrical , hollow ring made of a porous material , said ring being provided with chamber into which an air - lubricant / refrigerant mixture is injected by pressure , thereby creating an air cushion between the ring and the cursor that prevents mutual friction , lubricates the contact area between said ring and cursor and cools them to prevent wear and heating of the ring and cursor at high speeds . this makes it possible to significantly increase the working speed of the rings in twisting and continuous spinning machine .
