Patent ID: 7373880

Claim:
A printing press comprising: a frame having an operation side and a drive side; a plate cylinder cantileverly mounted to the operation side of the frame; a blanket cylinder cantileverly mounted to the operation side of the frame; a plate cylinder drive assembly mounted to the drive side of the frame and operatively coupled to the plate cylinder to rotate a shaft of the plate cylinder; a blanket cylinder drive assembly mounted to the drive side of the frame and operatively coupled to the blanket cylinder to rotate a shaft of the blanket cylinder; and a sidelay registration mechanism coupled to the plate cylinder drive assembly, the sidelay registration mechanism operatively coupled to the shaft of the plate cylinder to provide side-to-side adjustment of the plate cylinder, the sidelay registration mechanism comprising: a sidelay registration mechanism enclosure cantileverly mounted to the drive side of the frame, the sidelay registration mechanism enclosure housing a section of the shaft of the plate cylinder extending to the drive side; a first race coupled to the shaft of the plate cylinder by a pair of spaced apart first tapered roller bearings, the first race including a threaded outer surface; a second race coupled to the enclosure by a pair of spaced apart second tapered roller bearings, the second race including a threaded inner surface coupling the threaded outer surface of the first race; and a worm gear rotationally mounted on the second race and coupled to a drive screw, wherein rotation of the drive screw provides sideway movement of the shaft of the plate cylinder in the enclosure.
