This paper describes a contact micro-mechanics of a web feeding mechanism that consists of a rubber-coated steel roller and a steel roller. First, on the assumption of plane-strain, Green's functions of a cylindrical rubber with a steel core are calculated with the Boundary-Element Method. Green's functions represent deformations for concentrated normal and tangential unit forces on the rubber surface. Second, a contact problem of a rubber-coated steel roller and a steel roller is investigated using Green's function. Contact normal and tangential pressures, and strain of rubber are calculated with given loading and traction forces. Calculation results describe micro-slips and traction characteristics of this feeding mechanism. And the numerical predictions are confirmed by experimental results.
