A Method for Designing Film Sprockets
A method is described for determining the sprocket-tooth pitch and consequently the base diameter, the tooth profile shape and tooth dimensions of film moving sprockets together with the tooth location transverse to the direction of film travel. The method assumes that the film dimensions are known or can be determined. Computations are given for a 35-mm 32-tooth sprocket and data showing the allowable film stretch or shrink for various numbers of teeth in mesh.
