In a printing press adapted to print different size paper, after the imprinting, the paper passes rotatable cutting rollers whose rotative phase position is invariable; the paper next passes a folding knife cylinder and a coaxial gripper cylinder; the gripper cylinder has cam controlled fingers thereon; cams control these fingers; the rotative phase positions of the folding cylinder, the gripping cylinder and the gripper finger control cams are adjustable through respective control gearing for each of them and with respect to the invariable phase position of the cutting rollers; there is a rigid drive connection to the control gearing for each of the phase adjustable parts for jointly readjusting their phase positions for different size paper; individual calibrating adjustments disengageably connect each phase adjustable part from the rigid drive for individual corrections. |
