A dual flow air knife has been found to improve performance of a bottom feed vacuum corrugation feeder. A central pressure source (1) generates two air streams. One (2) is directed downward and via a short path against the location of the lead edge of the sheet to be separated. The other flow (3) is directed over a much longer path and with means to promote air entrainment and stream expansion. This second stream is joined with the first stream and is directed at the pocket opening created by the levitated stack. Articulated seals (4) minimize air pressure loss from the system.
