Description

ABSTRACT:
A sheet feed mechanism for feeding single sheets from a stack of sheets in a feed tray is adapted to feed such sheets, even though the sheets may be bowed, curved, or wavy in a direction transverse to the process or feed direction. The mechanism includes a pad support body. A plurality of individual sheet-engaging pressure pads are mounted on a lower surface of the body by connecting webs. The connecting webs have a fore and aft axis in the process direction and bend to permit the individual pads to move in the transverse direction so that the lower friction surface of the pad will conform to the non-planar or curved surface of the sheet to be fed from the stack of sheets.
