Abstract

The method involves using a balance device with ball weights (13) moving freely in a circular track (12) concentric to the drum (2). An imbalance detection unit (6b,c) produces an imbalance signal during rotation or fluctuations in rotation speed. The system is rotated at a speed below its critical rotation speed, or that of its bearing system. The balancing unit is made so that the ball weights are carried in the track at this rotation speed. An evaluation unit (6d) produces the curve of imbalance amount and accelerates the bodies to a rotation speed above the critical speed in the area of the curve minimum or on exceeding a threshold value.
