ABSTRACT:
A film dryer for the graphics arts, including a plurality of pairs of squeegee rollers feeding the film through the dryer, and removing water therefrom in the feeding operation. Air is drawn in and directed against the film to dry the film, the air passing through a series of chambers or spaces and passing over and cooling the drive motor and air circulating motor, the heat in the air, picked up from the motors, assisting in drying the film. The pairs of rollers are of successively greater diameters to progressively feed the film faster to keep the film taut and eliminate buckling thereof. The relatively great volume and distribution of spaces through which the air passes minimizes noise. The principal operating components are included in assemblies which are individually removable as units, for ease in servicing, such as a roller assembly which includes air tubes, drive motor assembly, blower-motor assembly, cover, feed roller, and drain pan. Additionally, breakaway clips are included, being positioned between end-butted sections of the rollers, that are individually removable from the rollers without disassembling any of the rollers or positions thereof.
