Abstract:
Storage and transport apparatus for a web such as photographic film and the like. The film, which is stored in randomly formed loops within the cassette, is withdrawn from the cassette, passed along a film gate including a projection gate by a drive wheel and pinch rollers which contact the film along its edges, and then is returned to the cassette. The design of the film channel, along with the absence of conventional film storage reels, provides a film transport system having low inertia and resulting in rapid frame access time coupled with precision frame positioning.
