    Patent number: 6494304
    Abstract: The present invention is directed to a pallet conveyor system that includes a pallet assembly having a pallet and a workpiece coupled to the pallet, a production area where a production task is performed on the workpiece, and a delivery area wherein the pallet assembly is moved to or from the first production area. The pallet conveyor system also includes a first conveyor assembly to drive the pallet assembly through the first production area and a chain conveyor assembly to drive the pallet assembly through the first delivery area. The first conveyor assembly operably engages the pallet in the first production area but not in the delivery area.
