An impression cylinder arrangement for an intaglio machine used for web-fed printing comprises a rotating impression cylinder with a circumference and a surface section extending partially around the circumference, and a cooling device for cooling the impression cylinder. The device for cooling the impression cylinder includes a plurality of continuous metal belts which run over two drums, which partially wrap the impression cylinder and are carried along by the latter during its rotation. These metal belts discharge the heat arising at the surface of the impression cylinder during the printing operation and are themselves cooled by the fact that one of the two drums is constructed as a hollow cooling drum through which a cooling means flows. The drums preferably are mounted in an adjustable frame and, when the printing machine is switched off, can be removed from the impression cylinder to the extent that the latter is not contacted by the metal belts.
