The Rotary-Buffer Squeegee and its Use in a Motion-Picture Film Lubricator
A squeegee developed to controllably remove liquid from a strand of film passing through it basically consists of a pair of plush-covered rollers that rotate at high speed counter to the direction of the film's motion. Roller contact on the film is very light. The squeegee has been used in a film lubricator. After film passes through the lubricant in a dip-tank, the squeegee dries, cleans and polishes the film. The squeegee has also been used to remove surface water before film drying and before soundtrack application. Compared to the Venturi squeegee, the rotary buffer uses little power, is quiet, is not limited in width and is easier to adjust and maintain. Compared to the wringer-slinger squeegee, the rotary-buffer requires separate power, does not absorb power from the film strand, is not limited in width and is easier to adjust. The rotary-buffer, however, is less compact than either.
