Abstract
The types of synchronous counters, or heads, in general use present several problems in the cutting of the multiplicity of negatives-used in color processes. The necessity of constantly threading and unthreading negatives to match the work print invites scratches and other damage to the negatives. — An improved type of synchronous counter has been developed which accommodates either three or six negatives (six being used in dissolves and fades) together with a work print. A special positioning lock allows the work print to be advanced or retarded in relation to the negative, and relocked in frame. To facilitate threading, the keeper rollers are designed to lift into a vertical position, thus making it possible simply to set the film onto the sprocket without having to slide it under or over rollers or sprockets. A novel arrangement of a lucite stripping-shoe allows illumination of the film from beneath in order to locate frame lines.
