Abstract

A transport roller rack for automatic film developing machines, which employs gear driven rollers arranged in a staggered pattern, and spaced so closely together that the film follows nearly a straight path between the rollers. Each roller (18) has a driving gear at its end. Every other pair of adjacent rollers rotating in mutually opposite directions have these driving gears at the same given ends and in mesh with each other. The intervening pairs of adjacent rollers rotating in mutually opposite directions have their driving gears at the ends opposite the said given ends, and also in mesh with each other. Thus, alternate pairs of counter-rotating rollers are driven by corresponding pairs of roller driving gears but from opposite sides of the rack. Extending along the roller driving gears 94 at each side of the rack is a train of larger diameter power gears 92, meshing with each other in a staggered pattern. Selected ones of these power gears coaxially rotate roller driving gears in different meshing pairs of such gears. Extending along these (intermediate) power gears 92 is a train of still larger diameter (main) power gears 90 which drive one another by meshing. Different ones of these main power gears coaxially rotate smaller gears, which in turn through meshing rotate the intermediate power gears positioned on the same side of the rack. <IMAGE>
