Abstract
A self-centering roll includes a body, a first layer of rubber surrounding the body, and a second layer of rubber surrounding the first layer, the rubber on the first layer being softer and of lower density than the rubber in the second layer. Flexible projections are formed in the second layer of rubber on each side of the transverse center of the roll extending outwardly from the roll body toward the transverse center of the roll.
