In this paper, we present a friction drive and a paper transportation characteristics of a long rubber-layered roller. Deformation of the rubber-layered roller in the axial plane are calculated with the Boundary Element Method (BEM) at fifty sections of the roller considering deformation of the steel core of the roller that is calculated with Finite Element Method (FEM). Calculated static pressure between the rubber-layered roller and the steel roller agrees well with experimental one if hardness of rubber is Hs69°. A friction drive characteristic of the rubber-layered roller and the steel roller is investigated numerically and experimentally. It is shown that if we assume certain loading torque on the steel roller, the velocity of the steel roller can be predicted by the numerical simulation. Moreover, a paper transportation characteristic of a set of rollers is investigated. The values of measured paper velocity spread widely because of the fractuation of the rotation velocity of the driving motor, however, their average agrees well with the predicted one.
