Abstract
A folding apparatus in a rotary printing press utilizes a cutting blade cylinder, a transport cylinder and a folding jaw cylinder. Operation of the various assemblies on the transport cylinder, such as folding blades and gripper systems is accomplished by control cams and associated cam rollers. The control cams are carried on the transport cylinder and rotate in the direction of the transport cylinder and at a speed which is different from the speed of rotation of the cylinder itself. This ensures low wear of the control cams and of the cam rollers.
