Abstract
A plurality of first rollers are rotatably mounted on a shaft symmetrically about the center of the shaft. The shaft is biased toward an axis about which a plurality of second rollers are mounted for rotation so that the first and second rollers contact each other. The shaft is supported for movement in a plane toward and away from the axis, and for rotation about an axis through the center of the shaft at right angles to the plane. A drive mechanism is provided for driving either the first or second rollers to forward a sheet between the nip of the rollers.
