Definitions

the invention relates to a roller press consisting of at least two rollers forming a wide press nip according to the preamble of claim 1, as used for example in the dewatering or smoothing of a fibrous web.
rollers include known from DE-OS 43 22 876, wherein the roller shoe supporting the roller jacket is divided into sections in order to influence the smoothing result in the web running direction.
WO 93/12290 is again about keeping the roller axes exactly in the press plane.
the invention is therefore based on the object of providing a roller press which enables a largely uniform press nip even when the counter-roll is not controlled by deflection.
the change in the outer circumference of the roll shell of the press roll in the axial direction should be as small as possible and be carried out uniformly, so that the speed differences occurring on the surface of the roll shell (viewed in the axial direction) do not have a negative effect on the material web.
the outer circumference of the roll shell, or its change in the axial direction, can already be influenced during manufacture by the fact that the inner circumference and / or the wall thickness of the roll shell of the press roll changes from the roll center in the axial direction towards the roll ends .
the axial To change the circumference via a thermal influence on the roll shell can be done from the inside, for example by tempering the lubricating fluid of the support elements and / or from the outside, for example inductively or with hot air.
the roller press shown in FIG. 1 consists of a press roller 4 and a counter roller 8 arranged above it. While the counter roller 8 is a full roller, the press roller 4 consists of a very flexible roller jacket 6, which can be rotated about a fixed support 5 for example, is mounted on the carrier 5 via a plurality of axially closely spaced support elements 7.
the support elements 7 are pressed hydraulically and can be designed to be independently controllable.
the gap between the support surface of the support element 7 and the roller jacket 6 can be lubricated hydrodynamically and / or hydrostatically.
the support surface of the support elements 7 is concave, so that a wide press nip 1 is formed between the press roll 4 and the cylindrical counter roll 8, as is used, for example, to smooth a fibrous web.
the desired press force in the press nip 1 is substantially above the weight of the counter roll 8
a largely uniform press nip can be achieved in an inventive manner by the outer circumference of the roll shell 6 of the press roll 4 starting from the center of the roll in the axial direction the roller ends reduced.
the roller press according to FIG. 2 consists of 3 rollers arranged approximately one above the other, the counter-roller 8 being arranged between the two other rollers and forming a press nip 1 or 10 with them.
the press and counter rolls 4 and 8 are constructed as in the first embodiment.
the third roller arranged below the counter roller 8 is designed as a suction roller 9.
a separate drainage belt 3 assigned to it is passed through each press nip 1.
Such a roller press can i.a. serve to dewater a fibrous web, although it is of course also possible, for example, to guide a dewatering belt 3 through both press nips 1 and 10 or to use only a strip-shaped support element 7 instead of the support elements 7.
the counter roll does not require deflection control.
the circumference of the roll shell 6 of the press roll 4 can be influenced by the fact that the inner circumference and / or the wall thickness of the roll shell 6 of the press roll 4 changes from the roll center in the axial direction towards the roll ends.
