Abstract: The present invention relates to an apparatus for cooling material to be printed and printing machine elements at sheet-fed rotary printing machines by means of cooled compressed air. It is an object of the present invention to provide an apparatus which requires little space, is able to cool effectively the material to be printed as well as the machine elements, which are undesirably heated by the dryers. Pursuant to the present invention, this objective is accomplished by providing an apparatus wherein cooled, compressed air is supplied over one or more sheet-guiding devices for guiding the sheets pneumatically along the sheet-guiding path, and a cooling device is disposed in the cross section of flow of the compressed air or the sheet-guiding device.

Abstract: A device for cooling a material web in a web-fed rotary printing machine, includes a heating device for producing waste heat for evaporative cooling of a cooling medium, and a cooling configuration through which the cooling medium is directable for web cooling. A first quantity of the cooling medium is evaporated and a second quantity is cooled by removal of heat of evaporation. A vapor generator produces vapor at least partly by the waste heat from the heating device. At least one vapor-jet vacuum nozzle is operatable by the vapor for producing a negative pressure. The cooling medium is to be subjected to negative pressure in a negative-pressure chamber for at least partial evaporation and for cooling. A dryer including the cooling device, a printing machine including the cooling device or the dryer and a cooling method are also provided.

Abstract: A drier intended for drying printing ink applied to a material by a printing machine, incorporating a conveyor device consisting of a support for the material as it passes through the drier and at least two organs which emit ultra-violet radiation, UV radiation, for the purpose of drying and/or hardening the printing ink. These two organs which emit UV radiation are located at such a distance from each other that a material which has passed beneath the first organ, where it has been exposed on the one hand to UV radiation for the purpose of hardening the printing ink and on the other hand to the heat emitted by the organ which emits UV radiation, will be able to pass through a section which will cause the temperature of the material to fall before the material passes beneath the second organ.

Abstract: In some examples, a sheet-fed printing press includes a dryer for drying sheets printed by a non-impact printing device. A cooling unit is directly downstream from the dryer in the transport direction, and includes a cooling module above a conveying plane. The cooling module uses air as a cooling medium, and may include a blower module with blower nozzles that blow the cooling medium onto the surface of the sheets being cooled. The blower module forms, with a guide surface, a gap with respect to the surface of the sheet being cooled. The guide surface of the blower module is arranged at a height above the surface of the sheet being cooled so that the cross-section of an outer annular gap, through the cooling medium exits, is smaller than or almost equal to a sum cross-section across all opening surfaces of the blower nozzles in the guide surface.
