Abstract

1280801 Coating apparatus EASTMAN KODAK CO 2 Jan 1970 173/70 Heading D1L In the coating of a moving web W the liquid coating material is fed to a hopper 10 from a supply line 14, the hopper, which consists of three sections, the centre one being bifurcated defining the rectangular orifice through which liquid coating material is fed, having an ultrasonic transducer attached to it. The transducer vibrates the hopper to provide a smooth flow of coating material. In the described embodiment a photographic film is coated with a magnetic stripe for sound recording.
