Abstract: An apparatus and method for rapidly drying and curing a waterborne coating as applied by a spray gun, or other means, to a product traveling on a moving continuous conveyor track. The conveyor track passes through a drying section which uses recycled filtered air to dry the coating and then into a curing section which uses an irradiator and airflow to rapidly cure the coating. The irradiator is cooled using an air flow and a damper assembly system.

Abstract: A drying apparatus and method utilizes radiant heat and forced air to provide for rapid drying of photosensitive material without emulsion side contact. The forced air is supplied through air passages formed between cover members that partially surround radiant heating bars, and is directed onto the photosensitive material where it impinges upon the photosensitive material. As the air passes through the air passages, it is heated by radiant heat from the heating bars. The heated air increases the drying effect of the drying apparatus and at the same time, impinges on the photosensitive material in a manner which assists in holding the photosensitive material firmly against, for example, drive rollers.
