Abstract

A low-oscillation and space-saving drive for a changeable format folder of a rotary printing is provided, the rotary printing machine having rotating subassemblies that can be driven, in particular a cutting cylinder, a pin folding blade cylinder, a folding jaw cylinder, a gripper folding blade cylinder, and perforating cylinders belonging to a perforating device. The drive is split up into individual subsystems, and each subsystem is assigned a controlled-position drive motor. In the event of failure of a drive motor, the drive continues to operate without functional impairment.
