FIELD: technological processes.
SUBSTANCE: invention relates to the field of manufacturing of the variator belts of vehicles using the technology of preventing nitriding defects. In a drum made of polymers, a closed metal ring is polished, a cleaned ring is rolled, nitrided and the adhered polymers are removed. The device comprises a holding tool, a rotation mechanism, a washing tank with an ultrasonic cleaning fluid, and an ultrasonic wave generator.
EFFECT: elimination of nitriding defects.
