A method for mounting and dismounting a doctor blade chamber in a support holder on a printing unit as well as an apparatus in which the doctor blade chamber is placed in the support holder in a mounting position and subsequently is brought in contact with a roller, preferably, an anilox roller, in a position of operation. The method and the apparatus advantageously have the doctor blade chamber disposed with the opening upwards in the support holder, preferably in a horizontal position or in a position at such a small angle that ink does not run out of the doctor blade chamber, and is brought into a position under the roller, after which the doctor blade chamber is brought into contact with the roller and pivoted about an axis coinciding with the rotary axis of the roller, into the position of operation.

A printing unit with a rotary roller and an ink chamber with an elastic sealing doctor blade (2) which in a curve with decreasing curvature extends from a holder (6) to a tangential point of contact on the surface of the rotary roller. A packing follows the curvature in order to seal between the sealing doctor blade and the ink chamber.

The invention concerns a method for dismounting as well as mounting a replaceable sleeve on a rotatable and radially displaceable roller (1) for a printing unit in a printing machine. The invention furthermore concerns such a printing machine with at least one printing unit, wherein the roller at the ends is provided with bearings (4, 9) arranged in two radially displaceable slides (6, 12) on the printing machine, and where the roller can be released from the printing machine at one end of the roller. The new features of the method and the printing unit according to the invention are that the roller is provided with displacing means, and by these is displaced in its longitudinal direction prior to dismounting a sleeve, whereby the roller is drawn out of engagement with the one fixed and radially displaceable slide, after which the slide and the roller may be displaced radially in relation to eacht other, and whereafter the sleeve is released and dismounted by being drawn off the roller in its longitudinal direction.

METHOD AND ARRANGEMENT FOR MANUFACTURING PACKAGES IN A DIGITALLY CONTROLLED PROCESS
Packages are manufactured in a digitally controlled process. A digital printing machine (101) produces printed workpieces and a cutting machine (104) cuts packaging blanks (105) from them. A conveyor line (107) transfers the printed workpieces automatically from the digital printing machine (101) to the cutting machine (104). A digital control system (109) exchanges digital control information with at least the digital printing machine (101) and the cutting machine (104).
