-1- ABSTRACT OF THE DISCLOSURE Apparatus for driving n sheet into a corner registration with registration members defining two orthogonal registration lines, including a sphere mounted to overly and drivingly engage a sheet being so registered, said sphere being rotatable on variable axes and vertically and laterally movable relative to the sheet, including a drive engaging the sphere for rotatably driving said sphere and a sheet in an initial direction of rotation towards both orthogonal registration lines, but allowing changes in the direction of rotation of the sphere and lateral movement of the sphere relative to its retainer and different positions of engagement thereagainst in response to the different reaction forces on the sphere from a sheet being driven by said sphere, and including a normal force control system asso- ciated with the retainer for automatically varying the normal force between the sphere and the sheet being driven in response to the lateral movement of the sphere and the reaction force, this normal force control preferably being provided by selected non-uniform (higher frictional rolling resistance or differently sloped) sectors of the sphere retainer interior surface.
