Problems solved by technology

[0006] However, a difficulty associated with this prior art device is that components of the substance mixture are contained in the liquid coming out of the substance mixture, and these components reach the slider guide, causing it to move slowly, since this must be done via the positioning center. The shaft exerts a very high actuation force for displacing the guide block relative to the blade bar
Therefore, the positioning mandrel must be oversized, or the slider guide must be cleaned more frequently

Embodiment Construction

[0034] Reference is now made to the figures in the detailed drawings, and first and particularly to the figure 1 , shows a doctor bar 1, a support bar 2 assigned to the doctor bar 1 and a web 3, also called a screen, which is located above the doctor bar 1 in a facility for producing a paper web . The web 3 runs over a wear layer 11 located on the doctor bar 1 . The scraper bar 1 is provided with a scraper edge 12 through which liquid is scraped off the wire 3 , coming out of the pulp (ie the mixture of substances) present on the wire 3 and reaching the underside of the wire 3 .

[0035] The scraper bar 1 is coupled to the support bar 2 through connecting rods 4 and 5 which are rotatably mounted on the scraper bar 1 and on the support bar 2 . Furthermore, a positioning device 6 is provided, by means of which the doctor bar 1 can be displaced parallel to the support bar 2 . The distance of the scraper bar 1 relative to the support bar 2 is varied by the displacement of the s...

Abstract

A device for adjusting a doctor bar (1) in a production line for producing paper webs, said device having a wire (3) to which the doctor bar (1) is assigned, said doctor bar (1) Oriented transversely to the direction of movement of the web and at a distance from each other. The scraper bar (1) is supported by the support bar (2) and can be adjusted relative to the support bar (2) and thus relative to the web (3) by positioning means (6). The scraper rod (1) and the support rod (2) are connected together by means of connecting rods (4, 5) installed thereon. The distance or angular position of the scraper bar (1 ) relative to the support bar (2) and to the web (3) can be adjusted by displacement of the scraper bar (1 ) relative to the support bar (2).

Description

[0001] This application claims priority under 35 U.S.C. §119 to Austrian Patent Application A 404 / 2016 filed September 1, 2016; the entire content of the earlier application is incorporated herein by reference. technical field [0002] The invention relates to a device for adjusting doctor bars in a production line for the production of paper webs, said production line having a wire to which doctor bars are assigned, said doctor bars being transverse to the wire The directions of movement are oriented and at a distance from each other. The doctor bar is supported by the support rod and can be adjusted relative to the support rod and thus relative to the web by positioning means. Background technique [0003] Prior art production lines for the production of paper webs have separate wires caused to rotate on which a mixture of substances for production of the paper webs is deposited at the beginning of the production line. In order to remove the liquid contained therein from ...
