Abstract
Paper feeding systems with rubber-covered roller drive are widely used in information processingdevices such as copy machines, printers and ATM. It is important in their designs to control the paper velocity with precision. It's experientially known that the velocity ratio depends on many factors such as the normal force, the frictional coefficient and the rotative velocity. Therefore, in this paper, we deal with the effects of some factors on the velocity ratio by doing the experiment and the finite element analysis in the paper feeding system with rubber roller and bed.
