ABSTRACT:
A dryer apparatus in combination with a printing press for drying printed matter and coatings on containers as they are received from the printing press, including a shroud assembly for housing a shutter assembly and a UV lamp assembly for drying printed matter and coatings on the containers. The UV lamp assembly includes a housing, a UV lamp mounted in the housing, and a UV reflector mounted in the housing for directing UV light in a light path toward the containers; and guide rails and guide tracks for moving the UV lamp assembly between an operational position in the shroud assembly and a non-operational position outside the shroud assembly to allow the UV lamp to be serviced or changed. The shutter assembly includes a clam-type shutter, a shutter shaft for pivotally mounting the shutter located inside the shroud assembly, and a piston-cylinder mounted outside the shroud assembly for pivotally moving the shutter between a light-blocking position between the UV lamp and the containers, and a light-drying position wherein the shutter is moved out of the light path of the UV lamp to dry the containers. There is a second embodiment having dual UV lamp assemblies and dual shutter assemblies which operate in cooperation with each other within a shroud assembly.
