ABSTRACT:
Apparatus for removing photographic images from Mylar film comprising first and second abrading rollers and deformable and resilient pressure rollers which partially overlie the abrading rollers at laterally offset locations so different segments of the film are scraped by the respective abrading rollers. The film is advanced past the abrading rollers by feed rollers and overlying nylon rollers that are spring-biased down against the feed rollers with enough force to prevent slippage between the feed rollers and the film. A motor drives the abrading rollers at a much higher surface speed than that of the feed rollers.
