    Abstract: The present invention discloses an inking system for a rotogravure press. The inking system uses a cartridge to allow for a fast change of ink. Also, the system is set up to change of the gravure cylinder (11, 12) without changing the ink cartridge. Finally, the system can adapt to a whole set of gravure cylinder diameters. The invention uses an ink pan (13) with adjustable height, and an inking roller (10) partially dipped in the ink (20) of the pan. The inking roller (10) is part of the cartridge and can be automatically engaged and dis-engaged by the printing unit.

    Abstract: The present invention discloses an inking system for a rotogravure press and a printing unit. The inking system can adopt two different configurations: a configuration which is optimal for inks found in Asia, and another setting which is optimal for inks present in Europe. The inking system (1) uses a cartridge (2) to allow for a fast change of ink. Also, the system is set up to allow the exchange of the gravure cylinder (11, 12) without changing the ink cartridge. Finally, the system can adapt to a whole set of gravure cylinder diameters. The invention uses an ink pan (13) with adjustable height, and an inking roller (10) partially dipped in the ink (20) of the pan.

    Abstract: The present invention refers to a chill roll (1) with recirculation of water or other suitable fluid used in printing machines, such as in particular rotogravure printing machines. The chill roll (1) has the ability to minimize the friction forces with the printing support and can thus be used with fragile supports.

    Abstract: This invention discloses a system to automatically clean a doctor blade (1). The cleaning of the doctor blade (1) removes the dust particles or the dried ink aggregates. It is performed by a sliding blade (4), which slides over the doctor blade (1). By automating the cleaning process, we can place the safety equipment on the side of the print unit, thus allowing to position the blade (1, 4) closer to the printing roller (2) and improving the print quality. Also, the invention discloses a cleaning sequence where the dirt caused by the cleaning process is confined to a small portion of the print.

    Abstract: The present invention refers to a novel support for a doctor blade (31) in a rotogravure printing machines. The doctor blade (31) performs a smooth lateral oscillation to remove ink that tends to dry behind the doctor blade (31), and thanks to the lack of gearing for conducting the motion, the system is extremely precise and low in maintenance. The novel support is made of two elastic laminar members (41, 42) on each side of the doctor blade (31).
