ABSTRACT:
A conveyor system for transporting a web is described especially suitable for photographic development equipment, including a plurality of rotatable web transporting members such as rollers, which are driven at uniform surface speed, a plurality of power transmitting gears which are driven together and a plurality of cluster drive gears coaxially connected to respective power transmitting gears and driven thereby at the same rate of rotation. The pitch diameter of the power transmitting gears is larger than the pitch diameter of the cluster drive gears. The system also provides a plurality of clusters of gears which are driven by cluster drive gears to rotate the rollers.
The web is transported through the system at uniform speed.
