ABSTRACT:
A roller conveyor comprises an inner track formed from bearing material positioned in parallel to an outer track with a plurality of rollers rotatably disposed between the tracks. Each roller includes a central shaft having a necked portion near one end which necked portion engages one of a plurality of U-shaped slots formed in the inner track. A twin-V drive belt is supported on a plurality of open-faced pulleys for motion parallel to the inner track with the upper edge of the drive belt being exposed by the open-faced pulleys. The ends of the roller shafts beyond the necked portions extend beyond the inner track to form driven members which engage and are driven by the exposed upper edge of the twin-V drive belt to rotate the rollers.
