Abstract
A system for handling various items with increased functionality and decreased mechanical complexity is disclosed. The system uses a plurality of rollers mounted between pairs of drive chains or belts to impart a driving force to the items to be moved. The drive chains or belts can be reversible to change the direction of travel. The angle of attack, α, of the rollers can be adjusted between a negative angle and a positive angle by changing the phase between the drive chains or belts to change a component of the driving force. The rollers can be braked to increase a component of the driving force. The spin of the rollers can be changed with a roller belt to change another component of the driving force.
