FIELD: engineering. SUBSTANCE: device has vibration detector, amplifier of signal from vibration detector, and correction mechanism, which is controlled by signal from output of amplifier through electromagnetic relay. Correction mechanism is designed as heater, two cases and two rings with cylindrical recesses, which are connected to one another by means of four elastic caps. Cases and rings with caps provide two cylindrical chambers which are partly filled with easily melted material, which amount conforms to condition of filling hollow locations for any misbalance of drum. EFFECT: increased reliability of device operations, decreased power use. 1 dwg
