Abstract
A paper feeding system with rubber rollers is widely used in an information processing equipment such as a copy machine and FAX, ATM. In order to control the paper velocity, it is important in its design to estimate the effect of normal force and back tension on the velocity ratio of paper to roller rotation. We propose a new model on the paper motion and the contact mechanics in friction drives with rubber rollers. It describes the velocity ratio by using the deformation and micro-slip between the rubber roller and the paper which are calculated with FEA.
