The objective of this invention is to provide a sheet- fed press which will prevent sheets of paper from moving around or flapping, and allow the sheets of paper to be conveyed in a stable fashion even when a skeleton cylinder is used as the intermediate cylinder. The sheet-fed press according to this invention has 1) a first press cylinder which is an intermediate or delivery cylinder with a sheet guide unit having an arced form provided under the lower surface, and which consists of a space through which a sheet passes; 2) a second press cylinder which is an impression cylinder or alike positioned adjacent to the first press cylinder via a reception area; 3) a second air blowing means in the downstream segment of the reception area which supplies the air flow in the direction that the second cylinder is rotating; 4) a third air blowing means to supply the air flow by an air jet unit to blow air toward the reception area between the two press cylinders from a point upstream from that reception area; and 5) an air control means to control the air flows to said two air blowing means, by selecting one of said two air blowing means according to the thickness of the sheet being conveyed from the surface of the sheet guide unit, or by constricting the volume of air supplied to the two air blowing means. The second air blowing means mentioned above is formed by 1) a second air supply chamber in the rear side of the sheet guide surface which is located in the downstream segment of the flow of sheet; and 2) a second air vent in the downstream segment of the reception area through which air from the second air supply chamber is blown in the direction that the second cylinder is rotating.
