Abstract
Apparatus for feeding sheets from a stack of sheets on a sheet stack supporting tray which includes a sheet transport for feeding sheets from the tray. An air knife is disposed adjacent the front wall of the tray to inject air between the sheet to be separated and the remainder of the stack. The air knife includes at least one elastomeric member attached to its front wall that extends to a point immediately above, below or touching the sheet transport in order to inhibit multifeeding of sheets from the tray.
