Reversing control for film guide in processor - has three pairs of drive rollers and one deflection roller

摘要

The film feed is passed through a first pair of drive rollers (20,22) and strikes an angled guide plate (58) to feed to a middle pair of rollers (16,18), with the film turned through right angles. A fast rotating deflection roller (30) with a soft covering takes the leading edge of the film and moves it upwards to a second guide plate (62) which feeds to the third pair of guide rollers (12,14). The film is turned through 180 degrees without any danger of its bowing or creasing. The middle pair of rollers has a larger diameter roller (16) on the concave side of the film feed. The system is suited for wet and dry processing.PS.
