This paper describes theoretical and experimental studies of the velocity characteristics of a paper feeding mechanism that consists of a short rubber-layered roller and a flat plate. The effects of the normal load and the paper tension on the strain of rubber roller and the velocity ratio of paper transport velocity to the tangential velocity of the rubber roller surface are calculated by using Green's function of the rubber roller. In order to verify the numerical results, an experimental setup of paper feeding mechanism was prepared. The paper transport velocity and tangential velocity of rubber roller surface were measured experimentally. It was found that the load dependence of rubber friction should be considered in case of soft rubber roller. The load dependence of rubber friction was introduced to the improved analysis by using adhesional friction model. The new numerical results were found in good agreement with the experimental velocity ratio of sofe rubber roller.
