Abstract
Apparatus and procedure for accurately positioning and magnetically holding a flexible ferrous plate on the surface of a rotary printing cylinder. Movable registering pins and a permanent bar magnet are mounted to the rotary cylinder and controlled by a single operating means. The pins and magnetic bar are alternately moved toward and away from the cylinder surface such that, when the pins are initially projected to register with positioning holes in the plate, the magnet is withdrawn. When the pins are withdrawn the magnet is simultaneously advanced to 'grab' the leading edge of the plate. The operating means is controlled by a foot pedal linkage. The trailing edge of the plate is held in position by a second bar magnet. To remove the plate, the procedure is reversed so as to simultaneously advance the register pins and retract the bar magnet to release the leading edge of the plate.
