A sheet feeding apparatus for feeding a compilation of sheets to a process station, including: a sheet tray for holding the compilation of sheets; an air plenum, positioned above the compilation of sheets, the air plenum including an outer perimeter, and a corrugated surface for corrugating one of the compilation of sheets into predefine multiple spans; a blower for generating a vacuum force in the air plenum to drive one of the compilation of sheets into contact with the air plenum thereby corrugating one of the compilation of sheets into predefine multiple spans; a series of sets of seals around the outer perimeter of the air plenum, for sealing one of the compilation of sheets against the air plenum.
