Abstract
An improved apparatus for successively separating and feeding sheets from a stack of sheets is disclosed. A wave generator wheel, rotating in a plane generally parallel to the stack, and about a tiltable axis generally perpendicular to the stack, is tiltable in a first direction to contact the stack for shingling the stack, and in a second direction to contact the stack for restoring the stack to its unshingled state. Sheets in a stack are driven forward or rearward by simply tilting the rotating wheel. The wave generator wheel is used to first drive the stack's top sheet away from a feed nip, and to then drive the stack's top sheet into the feed nip.
