ABSTRACT:
In this machine, an optical coding device furnishes a plurality of code numbers one of which is stored upon each rotation of the wheel to be balanced when the latter rotates at a stable measuring speed. This stored number corresponds to the passage of the imbalance through a predetermined position. Thereafter, the motor driving the wheel in rotation is switched off and the number is retained in the store and compared, in the course of a new rotation of the wheel, with the instantaneous number furnished by the coding device. The result of this comparison is displayed by three indicator lamps. When, in the course of the new rotation, the imbalance reaches the position it had at the moment of storage, one of the lamps lights up and the other two lamps are extinguished. The balancing weight must then be fixed to the wheel in a position diametrally opposed to the predetermined position.
