Embodiment Construction

[0036] in figure 1 In the figure, a first variant of the equipment for processing continuously running paper webs, cardboard webs or other fibrous webs 1 during its manufacture and / or conditioning is shown. The equipment has a coating device 2 for coating liquid-to-paste coating medium, which is represented only as a black box, and at least one drying device 3 for drying the coated medium arranged downstream (also only in figure 1 Is only represented as a black box and for simplicity).

[0037] There is at least one traction press 4 for applying the required web tension after each processing device or various process steps not shown here. The traction press 4 is composed of a fixed (non-pivotable), that is, a driven roller 5 installed in a fixed bearing 5A and a pivotable moving roller 6, the rotating moving roller 6 is pressed by a swing bearing 6A To the fixed roller 4. The direction of rotation of the two rollers is indicated by arrow D. The pressing direction of the moving ...

Abstract

The invention relates to a device for treating a running paper, cardboard, or other fiber material web (1) during the production and / or refining process thereof, comprising at least one coating device (2) for applying a liquid or paste application medium, comprising at least one drying device (3) for drying the applied medium and comprising at least one draw press (4) for applying the required web tension after the individual treating devices, wherein the draw press (4) comprises a stationary, or non-pivotable roller (5) and a displaceable roller (6) that can be pressed against the stationary roller (5), together forming a press gap (7) through which the fiber material web (1) travels during the treatment thereof, wherein the fiber material web (1) partially enwraps the circumference of the stationary roller (5), that is, by a wrap angle on the inlet side and the outlet side of the press gap (7). According to the invention, a wrap angle (alpha) of greater than 5 DEG up to 180 DEG is provide for wrapping on the inlet side, while the wrap angle (beta) on the outlet side is negligible or insignificant, and that at least one auxiliary device (10) is provided for preventing air bubbles between the stationary roller (5) and the fiber material web (1) and for stabilizing the fiber material web (1) during the inlet side wrapping.

Description

Technical field [0001] The present invention relates to a device for processing continuously running paper webs, cardboard webs or other fiber webs during their manufacturing and / or tempering process. The device has at least one device for coating liquid to A coating device for a paste-like coating medium, at least one drying device for drying the coated medium, and at least one traction press for applying the required web tension after each processing device, wherein the traction press It is composed of a non-pivotable fixed roller and a moving roller that can be pressed against the fixed roller. The fixed roller and the moving roller form a pressing gap through which the fiber web passes when being processed, wherein the fiber web has an angle part The ground wraps around the circumference of the fixed roller. Background technique [0002] Fiber webs composed of paper or cardboard are usually treated with glue or starch dispersants or with pigmented coating media in order to i...
