An apparatus for feeding sheets has a surface over which a sheet may be fed, a sheet feeder for feeding sheets over the surface which has at least one feed roll rotatably driven in the feeding direction at least one nudger roll upstream of the feed roll for urging a sheet to be fed toward the feed roll, the at least one nudger roll being pivotally supported about the at least one feed roll, a drive to rotate the feed roll in the feeding direction, an endless belt drive means to couple the rotational movement of the feed roll to the nudger roll, means responsive to identified feeding conditions to stop the drive and terminate the rotation of the feed roll in the feeding direction and reverse the direction of rotation of the feed roll whereby the endless belt drive coupling reverses the direction of rotation of the nudger roll and creates a drive torque on the nudger roll which urges it upwardly away from the feed surface.
