Abstract
A device for unpiling sheets one at a time from a pile of sheets placed perpendicular to a supporting surface, includes a pressure arm engaging a first face of the pile. A single friction drive roller has an axis perpendicular to the supporting surface, arranged at a predetermined distance from the supporting surface. The second face of the pile is engaged with the roller along a first edge. A low-friction abutment is arranged in the vicinity of the roller, separated from the supporting surface by the roller and has a surface parallel to the roller axis and offset relative to the roller. A pad is disposed substantially perpendicular to the supporting surface and is movable towards the abutment along a second edge located downstream of the first edge.
