Abstract

A puncture or gripper cylinder is provided with at least one puncture strip that is provided with gripper pins or point needles. These pins are extendable from the cylinder to puncture and to grip a signature. At least one deflector is carried on the puncture cylinder and is extendable and retractable with respect to a surface of the cylinder. The deflector, when it is extended at least temporarily shields the signature from subsequent pins.
