Abstract
A husking roll section for use in combination with a second parallel husking roll section within a husking machine, includes a hollow core with an outside surface, and a husking sleeve affixed to and surrounding the outside surface of the core to form a husking surface. The sleeve includes at least one hardened sector comprising a rigid rib, and a resilient major portion which is formed from an elastic material and which is bonded to the rigid rib and core. The husking sleeve presents a plurality of helical lands and grooves. When the rigid rib is a metal rib which is affixed to the core outside surface, the elastic material which forms the resilient major portion is bonded to the rigid metal rib sides and to the core outside surface so that the rigid rib sides are completely covered by the elastic material, and the metal rib and the elastic material immediately adjacent thereto form the hardened sector. The hardened sector instead may be formed from a hardened rubber rib which is bonded to the resilient major portion.
