In a web-fed rotary offset printing machine, operating preferably with variable-format cylinders, both sides of the printing machine are covered, during the operation and resetting of the machine, so that no access, in particular no access to the printing units, is possible. For this purpose, an access module is used between the printing-units, which module is equipped laterally with covers which resemble window roller blinds and cannot be opened while the machine is in operation.

Rotary printing machine, having safety oriented access modules

A gripper cylinder for a folding apparatus, the gripper cylinder having a cylinder shaft on which a cylinder body is mounted and at least two gripper stations mounted to the cylinder body. The gripper stations include grippers and corresponding gripper bases. An adjustment mechanism is provided for adjusting the distance between each gripper and its corresponding gripper base to correspond to the thickness of a product to be gripped. The gripper mechanism is operative to simultaneously adjust all of the gripper stations.
