A Pneumatically Operated Film-End Detector and Film Brake for Continuous Motion-Picture Film-Processing Machines

T. J. Lawlor

Film-end detectors and film brakes are used on high-speed motion-picture film-processing machines to sense the end of a film roll automatically and hold the film end while a new roll is being spliced onto it. A pneumatically operated film-end detector and film brake have been developed which offer advantages over previous designs.
