Abstract
This paper describes theoretical and experimental study of steady-state characteristics of a paper feeder consisted of a short rubber-layered roller and a steel roller. It is assumed that the paper thickness and in-plane strain is infinitesimal and ignorable. Deformation and strain of surface of the rubber roller are culculated with our Green's function that has been derived under in-plane stress assumption with Boundary Element Method on cylindrical coordinates. In calurations, loading force between two rollers and paper tention are considered. Velocity ratios of paper feeding velocity to rubber roller velocity are derived from strain of the rubber roller. In order to confirm the numerical results, an experimental setup that consists of an endless paper and a paper feeding mechanism was prepared. Paper feeding velocity and rubber roller were measured experimentally. The experimental results agrees with the numerical ones.
