Abstract
Paper gripper improvement in a printing press of the type having a frame, a large paper carrying impression cylinder drum mounted on the frame and a plurality of retractable printing stations mounted on the frame and spaced around the drum. Each gripper has a stationary finger and a second finger reciprocatable with respect to the stationary finger. A cam is connected to operate the reciprocatable finger to grip the paper as it is fed onto the drum. To detect a missing paper, an electrical circuit is completed by contact between the stationary finger and the reciprocatable finger in the absence of a paper between them insulating them from each other, whereby the need for photo-cells or other detectors to detect missing papers is eliminated. The inking rollers are driven separately from the drum to facilitate retracting the printing stations in the event of a missing paper.
