Definitions

  • the invention relates to a roller press consisting of at least two wide ones Press nip forming rollers according to the preamble of claim 1 as they for example, when dewatering or smoothing a fibrous web finds.
  • rollers include known from DE-OS 43 22 876, the Sliding shoe supporting the roller jacket to influence the smoothing result in The web running direction is divided into sections. With WO 93/12290 it works again to keep the roller axes exactly in the press plane.
  • the invention is therefore based on the object of creating a roller press which also a largely uniform one when the counter roll is not controlled by deflection Press nip enables.
  • the change in the outer circumference of the roll shell of the press roll in Axial direction be as small as possible and take place evenly, so that the Adjusting the surface of the roll shell (viewed in the axial direction) Differences in speed do not have a negative impact on the material web.
  • the outer circumference of the roll shell, or its change in the axial direction can be influenced during manufacture by the fact that the inner circumference and / or the wall thickness of the roll shell of the press roll from the center of the roll dimensional changes starting in the axial direction towards the roller ends.
  • the axial Change in circumference via a thermal influence on the roll shell cause. This can be done from the inside, e.g. about the temperature control of the lubricating fluid Support elements and / or from the outside, for example inductively or with hot air.
  • the roller press shown in Figure 1 consists of a press roller 4 and a mating roller 8 arranged above it, while the mating roller 8 is is a full roll, the press roll 4 consists of a very flexible to one fixed carrier 5 rotatable roller jacket 6, for example over several Support elements 7 arranged axially close to one another are mounted on the carrier 5.
  • the support elements 7 are pressed hydraulically and can be independent of each other can be designed controllable.
  • the lubrication of the gap between the support surface of the Support element 7 and the roller jacket 6 can be hydrodynamic and / or hydrostatic respectively.
  • the support surface of the support elements 7 is concave, so that between the press roll 4 and the cylindrical counter roll 8 form a wide press nip 1, as used, for example, to smooth a fibrous web.
  • Press nip can be achieved in an inventive manner in that the outer Scope of the roll shell 6 of the press roll 4 starting from the roll center in the axial Direction towards the roller ends reduced.
  • the roller press according to FIG. 2 consists of approximately 3 rollers arranged one above the other, the counter roller 8 between the other two Rolls is arranged and forms a press nip 1 or 10 with each.
  • the press and Counter roll 4 and 8 are constructed as in the first embodiment.
  • the third roller arranged below the counter roller 8 is a suction roller 9 educated.
  • Such a roller press can i.a. serve to drain a fibrous web, although it is of course also possible for example, to run a drainage belt 3 through both press nips 1 and 10 or instead of using the support elements 7 only a strip-shaped support element 7.
  • the counter roll comes without one Deflection control off.
  • the circumference of the roll shell 6 of the press roll 4 can are influenced by the fact that the inner circumference and / or the wall thickness of the roll shell 6 of the press roll 4 starting from the roll center in axial Dimensionally changed towards the roller ends.
