Title: Method of an apparatus for unstacking a pile of sheets

Abstract: A pile of sheets arranged vertically next to one another is gently urged against a rigid metal plate that can be reciprocated back and forth very rapidly so as to pull the end sheet off the pile by suction and to return to rest against the pile of sheets before they have followed this reciprocation motion to the same extent as the end sheet. Once the plate pulls rapidly away from the end of the pile, pulling the end sheet with it, this end sheet is engaged by a suction roller and pulled laterally off the pile.
