Abstract: A device for holding film in a projector is disclosed, in which the film is loosely held between two transparent plates, and air is supplied between one of the transparent plates and the film, so as to clamp the film to the other transparent plate. Thereby the film is gently and positively held, and is also cooled.
Abstract: A film gate for image projection apparatus provides improved structure for directing cooling air across the surfaces of supported film. The outlets of the cooling air conduits are located adjacent edges of supported film and configured and oriented to create Coanda effect attachment of their issuing air streams to the film surfaces.
