ABSTRACT:
Apparatus for applying protective coatings to photographic films or papers in web or sheet form. More specifically, apparatus for applying protective coatings that are curable by actinic radiation is provided. The apparatus includes a feeding station for supplying film which may be either a feed spool or a sheet feeder for holding and supplying individual sheets of film. The apparatus further includes a conveyor for conveying the film through a coating station and a curing chamber to a receiving station which also may either be a take-up spool to receive coated cured film or a stacking device to receive a stack of individual sheets of film. The conveyor can either be a series of conveying spools or pulleys or an endless conveyor belt in the case of individual sheets of film. The coating station includes a coating roller having a pattern of grooves formed by winding wire onto the surface thereof or other pattern of surface indentations.
