ABSTRACT:
A roller conveyor, comprises a frame having oppositely disposed substantially parallel sides; a plurality of pulleys disposed on each side of the frame, the pulleys on one side being coaxial with the pulleys on the other side of the frame; a drive operably associated with the pulleys on one side of the frame for rotating the pulleys; and a plurality of rollers resting freely and disposed between adjacent pairs of the pulleys. Each of the rollers includes a first shaft portion and a drive sleeve secured to the first shaft portion such that rotation of the sleeve causes rotation of the respective roller and stoppage of articles being conveyed on the rollers causes slippage between the respective first shaft portion and sleeve. Each drive sleeve is engaged with the respective driven pulleys such that rotation of the driven pulleys causes corresponding rotation of the respective drive sleeves.
