Abstract

Apparatus for separating, counting a stacking sheets, including a feed roller and cooperating stripper shoe for permitting the passage of only single sheets fed therebetween, said sheets being moved along a curved path defined by a guide plate cooperating with the feed roll as the sheet emerges from the region between the stripper shoe and feed roll. The leading edge of the sheet moving along said curved path enters into a nip between an acceleration roller and an acceleration idler mounted on a common axis with the feed roll to abruptly accelerate the sheet and drive it into a stacker wheel which delivers the sheet to an outfeed stacker. The feed roll is provided with a plurality of surfaces of differing coefficients of sliding friction to facilitate separation of sheets.
