Problems solved by technology

However, this has the disadvantage that the centers of the rolls are no longer on the stacking plane, which increases stress and wear on the rotating parts, especially the flexible roll mantles

Embodiment Construction

[0016] Figure 1 shows a long nip roller press for dewatering fiderous webs, especially paper webs, which may be part of a paper machine.

[0017] A long nip roller press consists of a long nip press roller 1 and a driven counter roller 2 which interact within a press nip 3 . The long-nip press roll 1 and counter roll 2 define with their roll centers a superposition plane S, where superposition plane S extends vertically. Optionally, the long nip press roll 1 and the counter roll 2 can also be arranged in such a way that the superposition plane S extends at an angle or horizontally. At least one felt fabric 4 and fiber fabric 5 to be pressed are guided through the press nip 3 .

[0018] The long nip press roll 1 comprises a stationary support 6 and a roll mantle 7 rotatable about the support 6 and made of a flexible material such as rubber or plastic. The roll mantle 7 is tubular and is fixed at its ends to a mantle (not shown) positioned so as to be rotatable on the support ...

Abstract

A long-gap roller press for dewatering the fibrous fabric is disclosed. Said gap between rollers at one side is formed by a rotating cooperative roller and at another side it is formed by a long-gap roller, which has static supporter and a flexible cover able to revolve around said supporter. Said cover is supported on a slide plane of said supporter. A pallet of press can move relatively to the supporter in load direction.

Description

technical field [0001] The present invention relates to an extended-nip roll press for dewatering fibrous fabrics. Background technique [0002] A long nip roller press of this type is known, for example, from DE3503240C2, which has driven counter rolls associated with a stationary support element with a press shoe guided therein. The press pallet can be pressed by means of pressure oil in the direction of the counter rollers. The annular press housing is guided around the support element. The corresponding parts of the press pallet and the housing of the reaction roll form a long press nip through which the fiber fabric to be dewatered passes through this nip together with the press housing in the direction of fabric movement. For this purpose, the press pallet has an upper part with sliding guides along which the press housing moves. Depending on the required pressure distribution, the slide guides are adapted to the outer surfaces of the reaction rolls across the press...
