Abstract:
1. A sheet buffering and inverting device comprising: a sheet transport path receiving a stream of sheets at a first location and feeding said stream to a second location, each of said sheets in said stream initially having an orientation with a first edge comprising a leading edge and a second edge opposite said first edge comprising a trailing edge; and a plurality of sheet inverter paths connected to said sheet transport path and being approximately perpendicular to said sheet transport path, each sheet inverter path comprising: an additional sheet transport path branching off of said sheet transport path between said first location and said sheet inverter paths and being connected to a least one of said sheet inverter paths at said second end, said additional sheet transport path comprising additional sheet transport devices and additional gates that allow an additional selected sheet to be diverted into said additional sheet transport path and transported into said at least one of said sheet inverter paths at said second end so that said additional selected sheet is buffered and also maintains said orientation when subsequently inserted back into said stream at said first end.
