A sheet justifier provides a table having at least one rotational surface thereon that is substantially aligned with the table. A sheet is input to the table into contact with the rotational surface. A weighted ball is positioned over the rotating surface proximate an outer edge of the rotating surface. The sheet is grasped between the ball and the rotating surface and forced against a raised guide edge. Once the sheet is forced against the guide edge, all rotational driving force is translated in a downstream direction therealong so that the sheet is driven out of the guide edge with its edge aligned therewith in a justified orientation.

A sheet justifier comprising: a supporting surface for supporting sheets, the supporting surface having an upstream end for receiving the sheets and a downstream end for outputting the sheets; a raised edge guide extending in a line substantially from the upstream end to the downstream end of the supporting surface, the edge guide being aligned substantially along the downstream direction and being substantially free of gaps along a length thereof in the upstream to downstream direction; a plurality of rotating surfaces, each of the surfaces being located in an aperture on the supporting surface and each of the rotating surfaces being approximately coplanar with the supporting surface each rotating surface rotating in the same rotational direction on an axis substantially perpendicular to the supporting surface, each axis being aligned along a line that is substantially parallel to the line defined by the edge guide; a plurality of balls each contacting a respective one of the plurality of rotating surfaces and rotating therewith, each ball having a contact point on the respective rotating surface that is positioned between the raised edge guide and the axis of rotation of the respective rotating surface, the contact point being remote from the axis of rotation and the contact point being upstream from a line perpendicular to the edge guide taken through the respective axis of rotation; and a frame suspended over the raised edge guide and over each of the plurality of rotating surfaces, the frame including a plurality of apertures that retain each of the plurality of balls therein, the apertures enabling the balls to rotate freely in all degrees of freedom.
