Problems solved by technology

This means that the remaining small amount of the first ink is easy to contaminate other inks and make it no longer possible to print the chromaticity of the intended printing.
In this way, the quality of the finished printing is adversely affected or completely destroyed
If the ink is contaminated too much with the first ink and is not discovered until a new printing job is carried out, the second ink must generally be replaced with a new fresh ink, which results in a loss of ink in the printing unit and a printing loss. cost in the form of lost time

Embodiment Construction

[0066] Figures 1a-1c show a sealing arrangement 1 according to a preferred embodiment of the invention. The sealing arrangement 1 comprises a holding device 10 and a sealing device 20 comprising a first sealing plate 21 and a second sealing plate 22 . The holding device 10 comprises a first holding element 11 and a second holding element 12 and a stay 13, which are held together by fastening means 14a, 14b, 15a, 15b, which preferably consist of nuts 14a, 14b and screws 15a, 15b constitutes. The strut 13 of the holding device 10 comprises a third holding element 16 and a fourth holding element 17 which are connected parallel to each other and at a distance from each other to form a space therebetween.

[0067] The sealing arrangement 1 is used for sealing a chamber doctor device 30 used in the printing unit, which chamber doctor device is shown in FIGS. 2-6 . As can be seen from Figures 4a and 4b, the sealing device 1 is arranged at the end of an elongated cavity doctor blade...

Abstract

Device in a chambered doctor blade for printing units, which chambered doctor blade is arranged for applying ink, lacquer, adhesive or the like to a rotatable cylinder in the printing unit, comprising an elongate frame, which frame is arranged parallel to and outside the cylinder and on which are mounted two parallel, projecting and from each other separated doctor blades, also disposed parallel to the cylinder and arranged in operative position, to be resiliently and wipingly applied against the cylinder, where the doctor blades, when in said operating position, together with the surface of the frame facing the cylinder, the envelope surface of the cylinder together with two sealing means, are arranged to define an elongated chamber containing medium which is intended to be applied on the rotating cylinder, wherein sealing means (20) comprising a first and a second part (21, 22) forming a space there between extending in the axial direction of the cylinder (31) in which an inlet (51) of at least one drainage channel (50) is provided for diverting of to the space leaking medium. The invention further relates to an additional device in a chambered doctor blade (30), and a method for sealing a chambered doctor blade (30).

Description

technical field [0001] The invention relates to a device according to the preamble of claim 1 in a chambered doctor blade of a printing unit. Furthermore, the invention relates to a device in a cavity doctor blade according to the preamble of claim 12 . The invention also relates to a method for an end-seal chamber doctor blade according to the preamble of claim 23 . Background technique [0002] Chambered doctors are used as a device for inking anilox cylinders in flexographic printing units. [0003] Modern chambered scrapers typically consist of an elongated frame holding the scraper along its two parallel long sides parallel to the long sides and housing at its ends acting as end seals. equipment. [0004] When viewed in cross-section, the doctor blades are arranged such that their free longitudinal shanks are inclined inwards towards each other and at a distance from each other so that when the frame of the chamber is arranged parallel to the axis of the anilox cylin...
