A printing machine, preferably an intaglio printing web-fed rotary press, comprises a printing cylinder (1), which is dipped into an ink pan, a doctor blade (11), which can be placed against said printing cylinder, and comprises holding arms (29) that, in the area between the ink pan (5) and the doctor blade, hold scrapers (7) against the edge areas of the printing cylinder. Two slides (25) are guided in a longitudinally displaceable, however, non-rotational manner on at least one guide (16) that is fixed to the frame while being parallel to the axis of printing cylinder. Said slides support the arms that extend radially or in a manner that is transversal to the guide. The slides are subjected to spring action thereby causing the scrapers to be pressed against the edge areas of the printing cylinder. |
