ABSTRACT:
Multiple size plate registration system having a platen with a top planar surface. Channels are formed in the platen and open through the top planar surface. Parallel grooves are formed in the platen spaced transversely of the platen, extending longitudinally of the platen and opening through the top planar surface. Endless belts travel in the grooves and are used for advancing a plate onto the planar surface of the platen. First and second stop pins are mounted in the platen and are extendable above the top planar surface. Controls are provided for causing the stop pins to be selectably movable between retracted positions below the top planar surface and extended positions above the top planar surface. A guide is carried by the top surface of the platen and extends longitudinally of the platen on one side of the planar surface. Controllable snubbers are provided for snubbing a plate on the planar surface of the platen against the guide and against any one of said first and second stop pins extending above said surface so as to make it possible to precisely register at least two different sizes of plates on said planar surface.
