The inner core has a plurality of ridges extending generally lengthwise thereof. These ridges form a plurality of generally longitudinal lobes on an exterior surface of the conditioning roll. The inner core is preferably formed of extruded aluminum while the outer shell is preferably formed of a relatively thin layer of polyurethane, resulting in a conditioning roll that is lightweight.
