Title: Ultrasonic film cleaning apparatus

Abstract: An ultrasonic liquid film cleaning device having means for moving a film strip at high speeds between a pair of oppositely moving cleaning strips. The cleaning strips and the film are positioned for movement between a pair of beds which act as guides and compression surfaces for the sandwiched assembly of cleaning strips and film. Cleaning fluid is piped to the bed to wet the cleaning strips and thereby assist in the cleaning action. An ultrasonic device is mounted in each bed to activate the fluid which is absorbed by the cleaning strips. This activation of the fluid increases the cleaning power of the strips as they pass against the film.
