Problems solved by technology

A disadvantage of this dosing device is that ink drops from the ink that passes through the dosing gap but is not transferred to the fountain roller can accumulate on the front of the dosing lever
These residual inks can enter the interior of the mechanism and contaminate the mechanism, impairing the function of the mechanism

Embodiment Construction

[0013] exist Figures 1 to 4 Elements and components corresponding to each other are denoted by the same reference numerals.

[0014] first described in Figures 1 to 4 Common features of the embodiments shown in .

[0015] exist Figures 1 to 4 A detail of a printing press 1 is shown in each case. The printing press 1 is an offset lithographic printing press and includes an inking unit which includes ink form rollers, distribution rollers, intermediate rollers and an ink transfer roller. The inking unit is thus an ink delivery unit. In addition, the inking unit includes an ink fountain 2 with an ink fountain roller 3 from which the ink transfer roller removes ink. Furthermore, associated with the ink fountain 2 is a base body 4 which forms an ink fountain base inclined towards the ink fountain roller 3 . The ink fountain 2 is thus a so-called wedge-shaped ink fountain. The fountain bottom can be at least partially covered by a film which protects the fountain bottom fr...

Abstract

The invention relates to a dosing device (5) for an ink fountain of a printing press (1), which comprises a row of dosing levers (6). The dosing levers (6) are respectively supported in a hinge (8), wherein a convex curved surface which is arranged on the face of each dosing lever (6) facing to an ink fountain roller (3) is coaxially extended together with the hinge (8) corresponding to the dosing levers (6).

Description

technical field [0001] The invention relates to a dosing device. Background technique [0002] The dosing device is used to adjust the amount of ink that varies from ink zone to ink zone according to the printed image. The dosing element of the dosing device can be, for example, a dosing slide or a dosing lever. The metering lever can be used to actuate the ink tongue of the ink knife, which delimits the ink reservoir together with the ink fountain roller, as described, for example, in DE 199 25 403 A1. Alternatively, the metering lever itself can also delimit the ink reservoir, as described for example in DE 30 47 689 A1, JP 2007237539A or JP 2001150644A. [0003] In US 4711176 a dosing device is described, the dosing lever of which is pivotable about a hinge. The hinge is formed by a common pin in the form of a small rod and slots for receiving the rod. A disadvantage of this metering device is that ink droplets from the ink passing through the metering gap but not tra...
