ABSTRACT:
Handling of strip films is improved by providing a method of film handling capable of advancing films wound in either direction. The winding direction of the film is detected, and an air flow is generated and the film spool is unwound depending on this detection. After being preliminarily unwound, the film is positively engaged and fed by advancing rollers.
