Abstract
A belt guide for a drive belt of a roller conveyor that cants the belt in the skewed roller section of the conveyor so that an edge portion of the belt, and not the entire width, engages the skewed rollers to impart driving motion. This is accomplished by providing a series of free-wheeling cam followers that support the raised edge portion of the drive belt that contacts the skewed rollers. A second series of freely rotatable grooved wheels or sheaves is provided whose grooved portion captures the lower edge portion of the drive belt.
