ABSTRACT:
A duplex conveyor comprises a pair of relatively spaced parallel bars having mutually facing sides with a plurality of bearing blocks mounted for displacement along each bar. A support roller is rotatably journalled for rotation relative to each bearing block and the support rollers are adapted to underlyingly support a workpiece carrier. The bearing blocks have lateral guide surfaces for cooperatively engaging a workpiece carrier during movement thereof upon rotation of at least one of the support rollers. A drive belt roll is drivingly connected to each support roller, and a drive belt is in driving relationship to each belt roll to drive the support rollers and thereby move the workpiece carrier and a workpiece supported thereupon.
