ABSTRACT:
Apparatus for removing sheets one at a time from a face of a stack of sheets wherein a flow-line is established between a primary feed roller or belt and sheet seizing means downstream thereof defining a nip, a lever system downstream of the nip for creating relative separation between the face and the feed roller or belt, the lever system including first and second levers each having first and second portions and first and second fixed pivots, the first portion of the first lever being disposed downstream of the nip and located normally to obstruct the flow-line but being movable from the flow-line by the passage of a sheet therealong, the first portion of the second lever being effective for effecting relative separation between the face and the feed roller or belt, and the second portion of the first lever controlling pivoting of the second lever about the second fixed pivot in direct mechanical repsonse to the movement of the first lever first portion by a sheet moving downstream of the nip.
