摘要:
A method of operating an anilox printing unit in which ink accumulates on and detaches from a feed blade and, after detaching from the feed blade, forms ink accumulations on a screen roller, and in which a gap is formed between the screen roller and a further roller for the ink accumulations to pass through the gap without contacting the further roller, includes forming the gap by displacing the axis of the further roller and evening out the ink accumulations on the screen roller to such an extent that the ink accumulations that have been evened out pass the gap without contacting the further roller. A smoothing roller, for example, may be used to even out the ink accumulations. A printing press for carrying out the method is also provided.

An anilox printing unit includes, as inking unit rolls, an ink applicator roll and an engraved roll mounted in rapid change roll sockets, for removing the engraved roll from the roll sockets and inserting another engraved roll into the roll sockets by an operator. The engraved roll is hollow and a temperature control fluid flows therethrough. The engraved roll and the ink applicator roll each have bearer rings. A device which presses the bearer rings of one inking unit roll against the bearer rings of the other inking unit roll has springs for compensating for diameter differences as a result of manufacturing tolerances between the bearer rings of the engraved roll and the bearer rings of the other engraved roll and for compensating for thermally induced diameter changes of the bearer rings of the engraved roll. A printing press having an anilox printing unit is also provided.

A printing machine includes an inking unit having a roller and a doctor-type ink fountain associated with the roller. The doctor-type ink fountain has an adjustable rear wall for setting an ink level of printing ink stored in the doctor-type ink fountain. The rear wall has a flow profile for flow-mechanically influencing the printing ink.

In a method of washing an anilox inking unit of a press, a washing agent is introduced into the anilox inking unit. The washing agent is introduced into the anilox inking unit via a dampening unit or a part of the dampening unit.

In a method for cleaning an anilox inking unit, a doctor bears against a roller and an intermediate roller bears against the roller and on an engraved roller. During cleaning, the intermediate roller has been or is displaced axially. Because the intermediate roller can be displaced axially, edge regions of the engraved roller can also be cleaned during a cleaning operation.

A sheet-fed printing machine includes an anilox inking unit having a screen roller and an ink applicator roller, as well as a dampening unit having a dampener applicator roller. The ink applicator roller has an outside diameter which is more than twice as large as the outside diameter of the dampener applicator roller.
摘要:
An anilox printing unit contains an engraved roller, an ink applicator roller, a first cylinder and a second cylinder as elements. At least one of the elements is a cambered or quasi-cambered element. The ink applicator roller is preferably the element. Such a configuration of the element ensures a high quality inking process.

In a method for controlling the temperature of a press which has an applicator roller and a screen roller, the screen roller has its temperature controlled at different temperatures and the applicator roller has its temperature controlled at a constant temperature. In this manner, the choice of the screen roller temperatures can be set individually for each printing unit depending on the optical ink density values which the operator desires.
