Claim:
An apparatus for moving transport media along a path of travel, a plurality of transport media defining at least two groups of transport media, each group of transport media having substantially identical transverse dimensions with respect to one another within one group of transport media, while having substantially different transverse dimensions with respect to another group of transport media, the apparatus comprising: a plurality of rollers rotatably mounted in fixed locations spaced along a path of travel, at least some of the rollers having a first drive member and a second drive member associated therewith, the first and second drive members of one roller operably connected to different rollers for transmitting rotation between the rollers along the path of travel; at least one motor for driving the rollers interconnected by first and second drive members in rotation; and each one of the groups of transport media supportable on the rollers for movement along the path of travel in response to rotation of the roller by the motor, each transport media continuously engageable with at least two rollers simultaneously while the transport media moves along the path of travel.
