ABSTRACT:
An automated coating apparatus includes a coating unit for applying a curable liquid material to the entire edge-to-edge surface area of one side of a flexible sheet. The sheet is then received on a rotatable drum adjacent the curing device, and moved back and forth next to the curing device to cure the liquid material. The drum includes a plurality of apertures in communication with a regenerative blower for retaining the sheet on the drum during the curing operation without contacting the uncured liquid material on the opposite face of the sheet. The curvature of the drum functions to essentially counteract the tendency of the sheet to curl during the curing operation.
