ABSTRACT:
A moisture stripping device for non-evaporatively stripping moisture from a moving film such as a photographic motion picture film. The film is cleaned in a liquid bath which has ultrasonic energy applied thereto. The film leaves the bath and passes through an air nozzle which is supplied with a source of air pressure. The air nozzle consists of a split block having a film slot extending through the block. A plurality of air jets are conducted into the slot at opposite sides thereof. The film, wet with cleaning solution, enters the slot and is non-evaporatively dried by air pressure which forms a moisture barrier at the lower edge of the slot. The slot is only slightly wider than the thickness of the film, yet the film is protected from touching the sides of the slot by an air cushion formed by air jets directed at both sides of the film. The air jets are formed by a plurality of air holes in the split block. The holes conduct air from the air source to the film slot. A relatively large pressure drop is provided across the air holes wth the result that a uniform pressure is developed across the entire face of the film, preventing it from contacting the surface of the split block. The slot has sharp edges at the lower side which receives film to maximize the moisture barrier effect.
