Abstract

Apparatus for removing sheets from a stack of sheets and feeding the sheets one at a time to an output flow-path, said apparatus comprising a feeding nip formed by a frictional drive adapted to engage and propel a sheet in a forward direction in combination with a pressure member adapted to press a sheet against the drive means, a stripper adapted to restrain plural sheets from being fed along the flow-path and a traction nip comprising a roller disposed downstream of the feeding nip, the roller being biased to obstruct said flow-path but being movable by the passage of a sheet and adapted, upon such movement, to open the feeding nip.
