Abstract
A sheet handling apparatus in which sheets are automatically moved in sequence into a registered position on a work surface and then moved out of that position to make way for the next sheet is disclosed. The sheet handling apparatus includes a sheet transport for conveying a sheet over a receiving surface and including a drive surface engageable with a sheet on the surface, and a spring supported roller and stop arrangement for automatically varying the frictional engagement between the drive surface and a sheet on the receiving surface.
