Abstract (en)
[origin: WO2023041262A1] The invention relates to a sheet-fed printing press having a dryer (17) for drying sheets (64) printed by a non-impact printing device (13), the dryer (17) being designed as a hot air dryer and/or as a dryer for drying by IR radiation, wherein: a cooling device (36) is disposed directly downstream of the dryer (17) in the transport direction (T) of the sheets (64); the cooling device (36) has at least one cooling module (37) above a conveying plane (E) in which the sheets (64) are conveyed in a flat state through the cooling device (36); the relevant cooling module (37) is designed in such a way that it uses air as a cooling medium; each of the cooling modules (37) of the cooling device (36) is designed as a blower box (41); each blower box (41) is designed to direct the cooling medium onto the surface of each of the sheets (64) to be cooled; each blower box (41) has blowing nozzles (43); the cooling medium is blown by these blowing nozzles (43) onto the surface of the particular sheet (64) to be cooled; each blower box (41) is designed in such a way that it forms a gap (S37) with a guide face (42) to the surface of the relevant sheet (64) to be cooled; the guide face (42) of the relevant blower body (41) is disposed at such a height above the surface of the relevant sheet (64) to be cooled that the cross-section of an outer annular gap through which a volume flow of the cooling medium exits the gap (S37) is smaller than or almost equal to the total cross-section over all opening faces of the blowing nozzles (43) in the guide face (42).
