Abstract

Apparatus and method for coating lower surfaces of paper sheets with lacquer and drying the sheets include fans for simultaneously drying the sheets and for forcing the sheets upwardly against the lower surface of spaced-apart moving conveyer belts. The streams of air produced by the fans are directed upwardly against the paper sheets and against and through the conveyer belts, and the paper sheets are moved from a first location to a second location within the apparatus. Features provide for washing and cleaning the apparatus and for circulating the lacquer to keep the lacquer in a uniform mixed state.
