ABSTRACT:
Apparatus for feeding single sheets of paper from a stack of the sheets, including fixed upper and lower guide surfaces between which the sheets travel during feeding, a single, centrally-located feed roll, a registration roll downstream of the feed roll, the registration roll being activated at the end of a predetermined delay period beginning when the feed roll is activated, the delay period being sufficient to assure that a single sheet is moved into engagement with the registration roll before the end of the period, the separation between the upper and lower guide surfaces being greater at a location intermediate the separation and registration rolls than at the rolls to define a buckle-restraint region intermediate the rolls wherein buckling of the sheet occurs after engagement with the registration roll and before the end of the delay period, and the moving feed surface of the feed roll being adapted to slip with respect to the sheet after the sheet has buckled against the surface of the region.
