Abstract:
A rotary sprocket disc for driving motion picture film is characterized in its construction by sprocket teeth enabling interchangeable transporting of film strips of different dimensions. Certain teeth are so disposed around the sprocket disc that they will mesh with or engage the holes in different film strips, the latter having different strip widths, tooth hole sizes, and pitches.
