Embodiment Construction

[0031] Figure 1 shows, by way of example, a part of a printing unit of a web press. In the embodiment shown, the web press operates in a wet lithographic process. The web press is especially used for newspaper printing. The printing unit has at least one transfer cylinder 01 and a printing plate cylinder 02 cooperating with the transfer cylinder 01 as printing unit cylinders 01 ; 02 . The transfer cylinder 01 produces at least one printing image on a printing substrate (not shown), preferably on a material web, in particular on a paper web, with each rotation of the transfer cylinder 01 . In the operating state of the printing unit as shown in FIG. 1 , at least one inking unit and a dampening unit are arranged next to the printing plate cylinder 02 .

[0032] The inking unit has a plurality, preferably at least three, inking rollers 03; 04; 06, which bear against the plate cylinder 02 during the production process when the rotary printing press is in operation. A plurality ...

Abstract

The invention relates to an inking unit of a rotary press, comprising a film roller. According to the invention, said film roller has a structured outer surface that has a shore hardness ranging between 80 and 90 (D) and a stochastic structure, the latter being incorporated into the outer surface of the film roller by peening.

Description

technical field [0001] The invention relates to an inking unit for a rotary printing press with an oil film transfer roller according to the preamble of claim 1 . Background technique [0002] DE 44 39 144 C2 discloses an inking unit for a rotary printing press, which has an ink fountain roller, which takes ink from an ink reservoir, and a plurality of inking rollers, which apply ink to the printing unit cylinder, wherein an inking unit is provided to supply the ink from the printing unit. The ink flow of the ink fountain roller is divided into the main ink flow and the ink distribution rollers of the side ink flow, wherein in the main ink flow and the side ink flow, inking rollers which convey the ink from the ink distribution roller to the at least one inking roller are respectively arranged. The row of rollers located between the ink fountain roller and the ink diverter roller consists of 4 rollers arranged in a row, so the row of rollers is relatively long, so that when ...
