Abstract (en)

Method for adjusting the positions of printing cylinders (2), in which a central impression cylinder (1) is rotated to its initial position, a movable arm (4) provided with a sensor (5) is clamped to the central impression cylinder (1), and together with the central impression cylinder (1) driven by its own drive it rotates gradually to each printing cylinder (2), stopping therein, the printing cylinder (2) shifts to the adjusting position and turns, a reference sign (9) provided thereon aligns with the sensor axis, and after adjusting the last printing cylinder (2) the movable arm (4) rotates to its initial position and unclasps from the central impression cylinder (1). The rotary printing machine comprises at least two printing units (2, 3, 12) around the central impression cylinder (1), wherein the printing unit (2, 3, 12) comprises a printing cylinder (2), a raster cylinder (3) and an ink reservoir (12), and wherein the printing cylinders (2) are provided with a reference sign (9) on a printing sleeve, and further the rotary printing machine comprising a movable arm (4) rotatable around the axis of the central impression cylinder (1), wherein a sensor (5) for sensing the reference sign (9) position is provided on the movable arm (4).
