An Automatic Rewinding and Cleaning Machine for Motion-Picture Films
This paper describes an automatic machine in which motion-picture film rolls are rewound and cleaned in one operation at 360 ft/min. A new type of combination air and vacuum sqeegee permits cleaning of 3000-ft rolls at this speed. Use of the machine in production permits successive printing of negatives without other periodic wet-cleaning techniques.
