Abstract: An apparatus for feeding sheets having folded edges comprising: a support for supporting a stack of upright sheets respectively on an edge thereof; a sliding wall engaged by a toothed belt for feeding the sheets in a path of travel; an endless belt having an upper run disposed for engagement of the edges of the sheets for feeding the sheets in a direction extending transverse to the path of travel; and a front wall resiliently biased against each sheet fed from the stack for exerting a force in a direction opposite to the path of travel.

Abstract: Apparatus for feeding sheets respectively having an upright surface and a lower edge, the apparatus comprising: structure for supporting a stack of said sheets on said lower edges thereof; first structure for feeding said sheets of said stack in a downstream path of travel; second structure for feeding said sheets on said lower edges thereof from said stack in a direction extending transverse to said path of travel, said second sheet feeding structure including structure for frictionally engaging the upright surfaces of successive sheets; and structure for resiliently urging said structure for frictionally engaging into engagement with said upright surfaces of successive sheets.

Abstract: A sorter in which the various paper trays of the sorter may be randomly accessed is disclosed. The sorter includes a plurality of paper-receiving trays which are stationarily arranged in vertically spaced-apart relationship to one another at the downstream end of the sorter, and an upstream paper transporting and guiding device for receiving paper sheets from an upstream machine and delivering the same to selected ones of the paper trays. The deflecting device is pivotable at its upstream end and has its downstream end arcuately movable between the various vertical positions of the paper trays. A suitable indexing mechanism is provided for indexing the paper transporting and guiding device to selected ones of the paper trays.
