Abstract
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 there along so that the sheet is driven out of the guide edge with its edge aligned therewith in a justified orientation. A rotator can be provided to the sheet justifier according to this invention. The rotator can include one or more weighted balls that engage a rotating surface at points remote from an axis of rotation of the rotating surface and rotate a corner of the sheet 90.degree. as the corner passes through a gap between an upstream and a downstream portion of an edge guide. Sheets are received from the rotator by a justifier for transport further downstream.
