Abstract
A paper feeding apparatus includes a fluid-supply device, a connecting pipe communicating with the fluid-supply device, and a plurality of force units connecting to the connecting pipe, each force unit having a pressing wheel on one end thereof, wherein each pressing wheel operates in coordination with a paper feeding wheel for feeding paper. The force units output equal force according to the same hydraulic pressure so that the pressing wheels provide the same component force to the corresponding paper feeding wheel so as to improve the quality of paper feeding. Furthermore, a method for using the paper feeding apparatus is disclosed.
