New Processing-Machine Film Spool for Use with Either 35-mm or 16-mm Film
It was decided that a new film processing machine at Du Art Film Laboratories, Inc., should be capable of handling either 16-mm or 35-mm film. After a number of experiments to find the best sprocket and spool combination, a radically new type of spool distinguished by a tapered profile was chosen. The advantages of this design, as applied to sprocket-drive and friction-drive machines, are enumerated.
