Abstract
Paper from a bin (1) enters a nip between a drive roller (13) and a torque-limited restraint roller (15). The drive roller is mounted on a pivoted bracket (7), having a gear train of a drive gear (9) and a driven gear (11). The drive roller is coaxial with the driven gear and turns with the driven gear. The bracket is self-compensating in that it automatically applies normal force to the drive roller sufficient to permit movement of paper (3). When the paper is more than one sheet, sufficient force is automatically applied to the drive roller to move the top sheet while the restraint roller holds or moves backward the bottom sheet.
