TITLE AXIAL AND CIRCUMFERENTIAL REGISTER CONTROL APPARATUS FOR A CYLINDER IN A PRESS FRAME ABSTRACT OF THE DISCLOSURE A plate cylinder has a shaft end portion that is rotatably supported in a press frame for axial movement re- lative thereto. A gear hub is axially movable and coaxially positioned on the shaft end portion. A helical driven gear is coaxially positioned on and non-rotatably secured to the gear hub. The teeth of the driven gear mesh with the helical gear teeth of a drive gear fixed relative to the driven gear, circumferential adjustment housing is rotatably secured to the gear hub to permit rotation of the gear hub relative to the housing. The housing is non-rotatably positioned for axial movement in a support frame that extends outwardly from the press frame. Resilient members retained within the cir- cumferential adjustment housing urge the housing to move axially relative to the support frame. A circumferential adjustment mechanism is non-rotatably secured to the circum- ferential adjustment housing and axially move the housing toward and away from the main frame. The gear hub and the driven gear move axially with the housing relative to the drive gear to rotate the driven gear and the shaft end por- tion to adjust the circumferential register of the plate cylinder while the cylinder is rotating or is stationary. An axial adjustment housing is secured to the shaft end portion to permit rotation thereof relative to the housing. The axial adjustment housing is urged toward and away from the press frame relative to the circumferential adjustment housing by resilient members that are retained within the housing. The axial adjustment housing is threadedly secured to an axial adjustment mechanism that advances the housing toward and away from the press frame by the resilient members to axially move the plate cylinder shaft end portion relative to the press frame and thereby adjust the axial register of to plate cylinder while the cylinder is rotating or is stationary. - 2 -
