ABSTRACT OF THE DISCLOSURE Novel apparatus is provided for handling and counting sheets. The sheet handling and counting apparatus includes an infeed hopper for receiving a stack of single ply sheets, a feed roller having a pair of flanges of substantially uniform radius, and a stripper shoe forming a feed nip with the feed roller. The upstream end of the stripper shoe and the feed roller form a tapering throat portion for guiding sheets into the feed nip. An output location and transfer means receives sheets advanced from the feed nip, the feed roller extends through a slot in the infeed hopper and the flanges of the feed roller have a high friction surface portion for advancing the bottom sheet in the infeed hopper towards the feed nip and cooperates with the strip- per shoe to advance sheets only one sheet at a time beyond the feed nip. A notch is arranged in the flanges adjacent to the leading edge of the high friction surface portion of the flanges, the notch being sufficient to receive and thereby move the leading edge of a sheet engaging the high friction surface portion of the flanges into the nip in advance of the leading edge of the high friction surface portion. The annular periphery of the feed roller, including the high friction surface portion, is provided with an annular recess between the flanges. The width of the stripper shoe is less than the width of the annular recess and is positioned sufficiently close to the recess to urge sheets passing through the feed nip into a curved configuration to facilitate the feeding and stripping operation to feed single sheets towards the transfer means.
