  • Patent number: 5092241
    Abstract: The arrangement has a device for cooling the impression cylinder (2) with a plurality of continuous metal belts (6) which run over two drums (4, 5) which partially wrap the impression cylinder (2) 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 (4) is constructed as a hollow cooling drum through which a cooling means flows. The drums (4, 5) are mounted in an adjustable frame (7) and, when the printing machine is switched off, can be removed from the impression cylinder (2) to the extent that the latter is not contacted by the metal belts (6).

  • Patent number: 5074450
    Abstract: An intermittent web transport apparatus in a printing machine guides the web between two processing positions and through an intermediate festoon. Web alignment deviations from a nominal value are corrected by rotation of a pivotable frame that is positioned downstream of the festoon. A correction roller before the festoon effects a shifting of the web prior to its entry into the festoon.
