To study the stress and deformation distribution of the contact zone between the rubber roller and rigid roller, a mathematical model of rolling contact between the rubber roller and rigid roller is built. The model is derived from the paper feed unit. The collocation method is applied to obtain the solution of the dual series equations obtaining based on elasticity theory. Effects of normal load and rubber thickness are observed through the numerical examples. The observa- tions show that the stress of the contact zone is directly proportional to normal load, and inversely proportional to rubber thickness. It is available for improving the efficiency of rubber roller.
