An Automatic Threading Mechanism for a 16mm Sound Projector

Arthur Nupnau, Jaroslav Cherniavskyj

A 16mm sound motion-picture projector has been developed to include automatic threading of motion-picture film through the entire film path thereby eliminating the complexity of manual threading. The mechanism is equipped with movable guides to form the proper size of loops and tensions. It also has an automatic loop restoring device to retain the proper size of lower loop.
