Problems solved by technology

If the machine operator tries to compensate for this effect by readjusting the metering element, this results in mechanical contact between the metering element and the fountain roller and thus wear, which leads to damage to the machine

Embodiment Construction

[0030] exist Figures 1 to 6 In , elements and components corresponding to each other are denoted by the same reference numerals.

[0031] exist Figures 1 to 3 A printing press 1 with an inking unit 2 is shown in each case in a partial view. The printing press 1 is an offset printing press for printing sheets.

[0032] This partial illustration shows the ink fountain roller 3 and the ink fountain 4 of the inking unit 2 . In addition, the inking unit 2 also includes an ink application roller rolling on the printing plate, an axially moving spreading roller and a transfer roller, which are not shown in the figure. If the inking unit 2 is a roller inking unit, it consists of a blotter roller in periodic contact with the fountain roller 3, and if the inking unit 2 is a thin-film inking unit, it consists of feeding the printing ink from the fountain roller 3. A milled film roll whose peripheral speed is substantially equal to the peripheral speed of the printing plate.

Abstract

An apparatus for metering printing ink includes an ink fountain roller, an ink fountain and a mounting for the ink fountain. The mounting permits an adjustment of the ink fountain relative to the ink fountain roller. The mounting has at least one elastic element for generating a holding force. The mounting is configured in such a way that a force flux which results from the holding force deflects the ink fountain roller in such a way that its longitudinal outer contour is adapted to the longitudinal outer contour of the ink fountain. A printing press having the apparatus is also provided.

Description

technical field [0001] The invention relates to a device for metering printing ink according to the preamble of claim 1, comprising an ink fountain roller, an ink fountain and support means for the ink fountain, said support means allowing adjustment of the ink fountain relative to the ink fountain roller, In this case, the bearing device has at least one elastic element for generating a holding force. Background technique [0002] Such devices are subjected to complex loads during printing operations, which lead to bending of the ink fountains and ink fountain rollers. Various measures have been proposed in order to avoid or compensate for this disturbing bending. [0003] In DE 3033998 A1 it is proposed to shorten the bending length by fastening the ink fountain on the journal of the ink fountain roller. The fastening takes place by means of a traction device, for example a wire rope wound on a carrier ring which is supported on the journal of the ink fountain roller. F...
