Abstract: A wiping device of an intaglio printing press comprises a liquid tank storing a cleaning liquid inside, a wiping roll disposed in the liquid tank and contacting a plate of an intaglio cylinder for removing ink on a surface portion of the plate, a base plate disposed in the liquid tank, and a wiping roll cleaning sheet supported by the base plate and contacting a circumferential surface of the wiping roll for removing ink adhering to the circumferential surface of the wiping roll. The wiping roll cleaning sheet comprises a supporting wire net tautly supported on the base plate, a cleaning wire net supported by the supporting wire net so as to contact the circumferential surface of the wiping roll, and an elastic cloth supported by the supporting wire net so as to be interposed between the supporting wire net and the cleaning wire net, for pressing the cleaning wire net against the circumferential surface of the wiping roll. The wiping device requires less labor for maintenance and check.
Abstract: An inking device in a printing machine with an ink body filled with printing ink and with a blade. The blade can also be a chamber blade, for example. For temperature moderation, an insulation plate or a heat dissipation plate, by which the temperature of the blade can be adjusted, is arranged on the blade. The heat created by friction between the upper edge of the blade and the surface of the cup roller does not penetrate into the ink duct due to the insulation plate and the heat dissipation plate, so that heating of the printing ink is avoided.
