Abstract

Sheet alignment and feeding apparatus including a sheet feed table for supporting a sheet to be fed, a side registration edge along one edge of the feed table, a sheet feed roll rotatably mounted in the feed table so that its top surface is in feeding engagement with a sheet to be fed, a cooperating pinch device in contact with the top of the feed roll, the feed roll being canted at an angle to the side registration edge to simultaneously drive a sheet against the registration edge and in a forward direction, and the feed roll having a relatively low coefficient of friction. The effects of contamination on the feed roll are minimized and a more effective and reliable feeding operation is achieved.
