ABSTRACT:
A printing press electronic side guide registry apparatus for sheet stock to be printed on a printing press having a print cylinder, print stock forward motion advancer through the print cylinder, and a forward motion registry stop including a laterally movable side registry stock gripper device comprising a slide anvil positioned to be adjacent one surface of the stock, and a fluid cylinder positioned to be adjacent the opposite surface of the stock, aligned with the slide anvil to grip sheet stock therebetween, the slide anvil and fluid cylinder both mounted on a laterally shiftable support movable transverse to sheet stock forward motion, a nut connected to the support, and a laterally extending screw operably engaging the nut, a rotational servo motor drivingly connected with the screw for rotation of the screw to laterally drive the nut, support, fluid cylinder and slide anvil, and a sheet edge detector electrically associated with the servo motor to controllably actuate and deactuate the servo motor, whereby the presence of stock at a print station will cause the fluid cylinder to shift and grip the stock against the slide anvil and cause the servo motor to be actuated to rotate the screw and thereby move the nut, slide anvil, fluid cylinder and the stock toward the sensor, until the sensor senses the stock.
