Definitions

  • the invention relates to a roll shell for treating a paper, cardboard, tissue or other fibrous web in a machine for producing and / or finishing the same consisting of one or more plastic layers, of which at least one is compressible and at least one support element in shape a fabric, thread lay o. ⁇ .
  • the flexible roll shells for dewatering or smoothing the fibrous web essentially consist of a polyurethane matrix which is reinforced with a fabric or scrim.
  • roller shells are pressed to form a press nip by a contact pressure element to a counter-roller.
  • the object of the invention is therefore to reduce the load on the support element.
  • the fabric must absorb the major part of the load in the form of tensile stresses.
  • Press belts with porous and / or compressible layers are for example from US 4,701,368 , of the EP 1 293 601 , of the EP 0 859 082 , of the EP 1 162 307 and the US 4,552,620 which forms the closest prior art known.
  • the roll shell consists of several plastic layers, of which at least one is incompressible.
  • the outside of the roll mantle is formed by an incompressible plastic layer.
  • the grooves and / or blind holes are completely within the incompressible plastic layer.
  • the effect can be further improved if - if a plurality of carrier elements are present - all carrier elements are embedded in one or more compressible plastic layers.
  • each carrier element it is possible for each carrier element to be embedded in a separate plastic layer or a plurality of carrier elements in a common plastic layer.
  • the compressibility can be achieved or enhanced simply by a porous structure, in particular a microcellular structure of the plastic layer.
  • microcellular structures which are formed by closed, cellular bubbles within the plastic layer whose diameter is smaller than 0.3 mm.
  • the compressible plastic layer is formed by an elastomer, in particular polyurethane.
  • Microcellular structures can be produced relatively easily, especially in the case of polyurethanes, by the addition of water in the crosslinker, which leads to the formation of extremely fine CO 2 bubbles as a result of a chemical reaction.
  • air or an inert gas may also be mixed in the production of elastomers.
  • the density of the compressible plastic layer is less than 1.1 g / cm 3 , preferably between 0.4-0, 8 g / cm 3 .
  • the compression modulus E is between 1 and 5 MPa.
  • the incompressible plastic layer should be formed mainly because of the high wear resistance of an elastomer, in particular polyurethane.
  • the inside of the roll mantle is to be particularly wear-resistant and / or smooth, it is advantageous if the inside is formed by an incompressible plastic layer.
  • the inside of the roll shell should be formed by a compressible plastic layer.
  • Increased roughness can support, for example, the lubrication between the roll shell and a contact pressure, because it promotes more lubricant in the lubrication gap.
  • the ratio between the volume of the support element and the volume of the compressible plastic layer should be greater than or equal to 0.1, preferably greater than or equal to 0.2.
  • the distance between the unidirectional filaments should be less than 3 mm and the distance between crossing threads between 0 and 4 mm, preferably between 0 and 1 mm.
  • the roll shell 3 of the invention is part of a press roll, wherein the flexible and approximately cylindrical roll shell 3 is pressed by a pressing member 4 with concave pressing surface to a counter-roller 10.
  • the roll shell 3 consists essentially of polyurethane and, for example, a carrier element 5 in the form of a thread scrim for reinforcement.
  • the polyurethane is usually very wear-resistant, but relatively incompressible, there is a risk of permanent stretching or even a fracture of the support element 5, in particular when passing through batches o. ⁇ .
  • the carrier element 5 is embedded in a plastic layer 6 of polyurethane having a microcellular structure.
  • the microcellular structure is formed here by distributed existing bubbles 11, whose diameter is less than 0.3 mm.
  • This microcellular structure leads to an improved compressibility of the plastic layer 6 and thus relieves the carrier element 5 under pressure load.
  • the density of this compressible plastic layer 6 is between 0.4 and 0.8 g / cm 3 .
  • the roll shell 3 has according to FIG. 1 an outer, incompressible plastic layer 7 made of solid polyurethane.
  • roll shell 3 has in addition to the incompressible, outer 7 and an incompressible inner plastic layer 8 of solid polyurethane.
  • the wear-resistant, smooth inner plastic layer 8 allows a subsequent processing in the production of the roll shell 3, without the risk of the formation of open pores and thus a roughening of the surface.
  • the roll shell has in FIG. 2 on the outside in the circumferential direction grooves 9 for receiving water during the dewatering of the fibrous web. 1
  • grooves 9 extend completely within the incompressible, outer plastic layer 7, which has a positive effect on the wear and the dimensional stability of the grooves 9.
