An Automatic Sound-Track Editing Machine

The sound-track cutter requires a film reproducer in his daily routine work: a reproducer that can be threaded quickly and will not tear or damage the film, and will produce sound quality of sufficient excellence to judge splits or cut-outs in music recording. — Such a device has recently been developed, and its mechanical details and operation are described. By means of a geared motor drive and a series of friction rollers, the sound-track is fed past the light-beam of the reproducing system at standard speed, with a reversible feature that is automatic and instantaneous. No sprockets or clamp rollers are used, and the work of the cutter is speeded materially through its use.
