Abstract
A roll conveyor having paired counter-rotating grab rolls includes a reversing roll section on one grab roll for discharging material conveyed along it perpendicularly to the axes of rotation of the paired rolls. One roll of each pair is composed of separate conveying and discharge or reversing sections that are rotatable about a common axes and in opposing directions. The reversing section is provided at one end of the roll conveyor and cooperates with the other rolls at that end to tumble material transversely from the conveyor. The non-reversing rolls adjacent the reversing section are further provided with helical flightings of opposite hand that meet midway along the reversing section to gather material for sideways discharge.
