ABSTRACT:
A transport roller rack highly efficient in use of power, especially suitable for photographic film developing machines. The rack combines transport rollers in staggered, non-nip forming configuration, with a power gear train having coaxial power tap-offs to clusters of roller driving gears.
Each cluster has its own cluster drive gear, which is coaxially rotated by a larger power gear.
Roller driving gears belonging to adjoining clusters also mesh with each other, thereby uniting these clusters into a continuous train of intermeshing roller driving gears.
Also, the method of transporting film by the use of this rack.
