ABSTRACT:
A speed control device for a multi-motor drive mechanism for driving printing press components is described. The speed control device allows the control of drive motors experiencing different instantaneous loads. This is achieved in accordance with the invention by assigning the motor having the greatest load fluctuation as the master, with the other motors assigned as slaves. A signal indicative of the demand experienced by the master is smoothed and used to control the slave motors.
