Abstract
A drive system for an oscillating gripper of a sheet-fed printing machine has a main drive train and a controlled drive. The pregripper is mechanically coupled to the main drive train. The controlled drive supplies energy required to drive the pregripper in accordance with a position of the pregripper. The controlled drive at least approximately meets the discontinuous energy requirement of the pregripper.
