A delivery system of a sheet-fed rotary printing machine includes a device for inhibiting curl formation in a leading edge of a sheet, comprising blowing units disposed at a location of the delivery system whereat, as viewed in travel direction of the sheet, a forward region of a stack of delivered sheets is disposed. The blowing units are in vicinity of a location at which the leading edge of the sheet being delivered travels downwardly. The blowing units have respective means for directing a controlled air jet, with one directional component in the travel direction of the sheet and another directional component towards the middle of the sheet, against the underside of the downwardly traveling sheet in vicinity of the leading edge of the sheet tending to curl.
