ABSTRACT:
A shutter system cooperatively associated with a high temperature lamp-reflector assembly for curing a photosensitive coating on a substrate moving adjacent the lamp-reflector block comprises a reflector block having a cavity within which is mounted a high temperature lamp and a shutter system which includes a double acting cylinder with piston rod, two support-guide rod, bearing assemblies and a flat shutter plate supported in a cantilevered manner from the cylinder piston rod and support-guide rod, bearing assemblies. The shutter plate is moved on signal by the cylinder piston rod to a position between the reflector block and coated substrate to shield the substrate when its movement is interrupted and away from such position when the substrate is moving.
