Patent ID: 6966427

Claim:
An apparatus for moving a plurality of transport media along a path of travel, the 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 one motor for driving at least one of the rollers in rotation; at least one 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; each roller operably associated with a common shaft supporting a driven pulley and a driving pulley; and a plurality of elongate drive members engaged between adjacent rollers connecting the driven pulley of one roller with the driving pulley of an adjacent roller for transmitting rotation from the motor to the plurality of rollers along the path of travel.
