Abstract
A roller assembly for use with a conveyor for transporting a workpiece wherein the drive force applied by the roller is adjustable independent of the force generated by placing a workpiece on the roller. The roller includes an inner sleeve secured to a drive shaft of the conveyor. A roller is disposed about the inner sleeve and is frictionally fit along an interface between the roller and an inner sleeve such that when a weight is placed upon the roller, the frictional force occurring between the interface between the roller and sleeve causes the rotating inner sleeve to impart motion to the roller thus moving the workpiece. The roller includes a connection to the inner sleeve such that the coupling or frictional force between the roller and the inner sleeve is independently variable of any force generated by placing a workpiece on the roller.
