ABSTRACT:
Non-contact air film conveyors are suited for conveying elongated strips (46) of web material such as photographic film and include a track plate (12) having gas flow apertures (20,24; 72,74) extending through its thickness at angles to the surface of the track plate (.alpha.,.alpha.') and to the direction of movement of the strips (.beta.,.beta.', .gamma.). By directing air flow through some apertures (72,74) counter to the direction of movement, speed and acceleration control is achieved independent of the support given to the strips by air flow through other apertures (20,24). Baffles (28-36) and curved side walls (70,96) direct air back onto the film to flatten it during movement.
