  • Patent number: 4496143
    Abstract: A sheet feeding apparatus including an air flow sheet separation mechanism for feeding individual sheets of paper from a stack of sheets slanted slightly from the vertical. A flow of air established through a plurality of resiliently surfaced feed wheels draws individual sheets seriatim from the nearly vertical stack of sheets into driving contact with feed rollers located adjacent the upper edge of the stack of sheets and mounted for rotation about a horizontal axis. Each sheet is then drawn upwardly by frictional contact with the feed rollers into the nip of a pair of opposed feed rolls which are mounted for rotation about a horizontal axis parallel to the feed wheel axis. The sheet is then delivered by conveyors to a sorting mechanism or other sheet fed device.
