Wide Film Shrinkage and its Effects as a Factor in Determining Proper Dimensional Specifications for a New Standard

A. S. Howell, J. A. Dubray

Mr. Roebuck, in 1918,1 and Mr. J. G. Jones, in 1923,2 presented to this Society papers in which the all-important matter of film sprocket design was discussed and formulas given which served as a basis for the calculation of the diameters of the film sprockets; the pitch, thickness, height, and shape of the sprocket teeth to permit the accommodation of a chosen range of film shrinkage.
