Definitions

  • the present invention relates to a roll, in particular for smoothing paper webs, comprising a hard roll core, in particular made of metal, which is provided on its outside with an elastic covering layer consisting of an elastic matrix material and fibers embedded in the matrix material. Furthermore, the invention is directed to a method for producing such a roller.
  • Elastic rolls of this type are used, for example, in the calendering of paper webs.
  • an elastic roller together with a hard roller forms a press nip through which the paper web to be processed is passed.
  • the hard roller has an existing example of steel or chilled casting very smooth surface and is responsible for the smoothing of their facing side of the paper web, acting on the opposite side of the paper web elastic roller causes a homogenization and densification of the paper web in Preßnip.
  • the elasticity of this second roller thus prevents excessive compaction of the paper web, which would lead to a greasy appearance of the paper web.
  • the order of magnitude of the rolls is in lengths of 6 to 12 m or diameters of 800 to 1500 mm. They withstand line forces of up to 600 N / mm and compressive stresses of up to 50 N / mm 2 .
  • the plastics commonly used for the coating have a significantly higher coefficient of thermal expansion than the steel rollers or chill rolls commonly used, so that a high temperature increase axial stresses between the steel roller or chill roller and the associated plastic coating occur.
  • hot spots may occur at which detachment or even bursting of the plastic layer takes place.
  • a roller with a hard roller core is known, which is provided on its outside with an elastic cover layer.
  • the elastic cover layer consists of a plurality of layers, wherein in each case an unreinforced layer alternately follows a fiber-reinforced layer.
  • roller of the relevant part of the task is achieved by the features of claim 1.
  • a corresponding method according to the invention is specified in claim 8.
  • the reference layer has a thermal expansion coefficient, which is also different according to the fiber content in the radial direction from the inside out. Since usually the matrix material has a significantly higher coefficient of thermal expansion than the fiber material used, the respective resulting coefficient of thermal expansion of the fiber-interspersed matrix material thus depends both on the thermal expansion coefficient of the matrix material and that of the fibers. The more fibers in embedded in the matrix material, the more the resulting coefficient of thermal expansion equals the thermal expansion coefficient of the fibers used.
  • the fiber content in the radially outward regions of the cover layer must be chosen to be lower, otherwise the surface of the roller would be too hard and unsuitable for santinage.
  • the fiber content is substantially in the radially outward region of the cover layer equals zero. This ensures that the surface of the roller is as elastic as possible and after a corresponding Abschleifvorgang has a very smooth surface, since the fibers present in the reference layer do not reach to the surface of the cover layer. Furthermore, it is ensured in this way that the surface of the roller can be reground after a certain period of time, without the fibers present in the matrix material after the grinding process at the surface of the cover layer emerge from this and thereby reduce the smoothness of the surface.
  • the nip width can also be set as required. Since, in a roller with a very elastic coating, the hard counter-roller presses more deeply into the soft covering of the elastic roller, the width of the nip in the direction of travel of the paper web becomes greater the more elastic the outside of the covering layer of the elastic roller is. Thus, by setting a certain fiber content profile and in particular a certain fiber content at the surface of the reference layer, a desired nip width can be generated.
  • the cover layer comprises a radially outer functional layer and a radially inner connecting layer for connecting the functional layer to the roller core.
  • the bonding layer may consist of an elastic matrix material and fibers embedded in the matrix material, wherein preferably the matrix material of the bonding layer and the functional layer of the same material and in particular also the fibers of the bonding layer and the functional layer consist of the same fiber material.
  • the matrix material of the bonding layer in fiber bundles or so-called fiber rovings, ie in flat slivers, each comprising fibers of the same type, wound on the roll core, while the fibers of the functional layer can be wound, for example in the form of a nonwoven fabric on the bonding layer.
  • the fiber content of the bonding layer is higher than the fiber content of the functional layer, since in this way the bonding layer is fiber-dominated and the coefficient of thermal expansion of the bonding layer is determined primarily by the thermal expansion coefficient of the fibers. Thereby, the resulting coefficient of thermal expansion of the bonding layer can be adjusted to the thermal expansion coefficient of the roll core.
  • the fibers are radially distributed substantially uniformly over the bonding layer, wherein in particular the fiber content of the bonding layer varies radially from the inside to the outside, preferably decreases.
  • the functional layer is achieved in that the longitudinal stresses occurring in the event of heating uniformly over the radial Extension of the reference layer is distributed and thus occur at any point longitudinal stresses that lead to a violation of the reference layer.
  • the fiber content of the connecting layer in its radially outer region is substantially the same as the fiber content of the functional layer in its radially inner region.
  • a continuous transition between the connection layer and the functional layer is created with respect to the thermal expansion, so that a voltage-optimized connection is also created in this transition region.
  • the fibers are arranged in radially spaced-apart fiber layers, wherein in particular the distance between radially outer adjacent fiber layers is greater than the distance between radially inner fiber layers.
  • the fiber content of the connecting layer is preferably about 40 to 70% by volume, in particular about 50 to 60% by volume, preferably about 55% by volume.
  • the fiber content of the bonding layer determines both its stiffness, thermal conductivity and the coefficient of overall expansion.
  • a high thermal conductivity of the connecting layer is achieved by the relatively high fiber content, so that the heat of overheating points occurring during operation can be quickly discharged axially outwards, so that hot spots are prevented.
  • the fiber content of the functional layer is preferably about 5 to 20% by volume, in particular 8 to 12% by volume. Due to the reduced fiber content of the functional layer receives a lower stiffness than the tie layer, as required for the homogenization and densification of the treated paper web in the calendering. If, due to the reduced fiber content, the thermal expansion coefficient of the functional layer becomes too large, this can be reduced by an appropriate addition of fillers into the matrix material of the functional layer.
  • Fig. 1 shows a part of a longitudinally cut, for example made of steel roller core 1, which is provided on its outside with an elastic cover layer 2 also shown cut.
  • the cover layer 2 consists of an elastic matrix material 3, in particular a resin / hardener combination, in which a plurality of fibers 4 are embedded.
  • the fibers 4 may be, for example, carbon fibers or glass fibers or a mixture of carbon and glass fibers.
  • the rigidity of the reference layer 2 is increased compared to a reference layer made of pure plastic and at the same time, especially when using carbon fibers, the thermal conductivity is improved.
  • the fiber content in the radially inner region 5 of the cover layer 2 is markedly higher than in its radially outward region 6. This ensures that the cover layer 2 is more elastic in its radially outward region 6 than in its radially outer region 6 radially inner region 5, so that, for example, during the interaction of the elastic roller with a hard roller, this hard roller presses relatively far into the elastic outer surface of the reference layer 2, whereby a circumferentially long press nip is formed.
  • the thermal expansion coefficient of the cover layer 2 is also significantly influenced by the fibers 4. Since the metallic roll core 1 usually has a significantly lower coefficient of thermal expansion than the matrix material 3, the matrix material 3 expands significantly more than the roll core 1 with a corresponding heating in the axial direction. By adding the fibers 4, their coefficient of thermal expansion is of the order of magnitude of the thermal expansion coefficient of the roll core 1, it is achieved that in the region 5 of the reference layer 2, which has a high fiber content, the resulting coefficient of thermal expansion is similar to that of the roll core 1. As a result, with a corresponding heating, the region 5 expands in the axial direction by a similar value as the roller core 1, so that axially occurring longitudinal stresses are largely avoided.
  • the substantially continuously radially outwardly decreasing fiber content within the cover layer 2 ensures that even within the cover layer 2 the longitudinal stresses occurring during heating in the course radially outwards each have only low values that can be absorbed by the elasticity of the matrix material 3 ,
  • the fibers 4 are shown schematically within the matrix material 3 as fiber layers 7 extending substantially concentrically with the roll core 1.
  • the fiber layers 7 can be produced, for example, by winding fiber rovings onto the roll core 1, wherein a plurality of winding processes are carried out to form the cover layer 2 in order to produce a plurality of fiber layers 7.
  • the fibers or fiber rovings Before being wound, the fibers or fiber rovings can be subjected to matrix material 3 in the liquid state, for example by being drawn through a matrix bath. However, it is also possible that the fibers or the fiber rovings are wound dry on the roll core 1 and during or after winding with Matrix material are soaked until they are completely surrounded by this.
  • the fiber layers 7 have in the radially inner region 5 of the reference layer 3 a radially smaller distance to each other than in the radially outer region 6, wherein in the outermost region of the reference layer 2, no fibers are present, i. that in this area the pure matrix material 3 is present.
  • the uppermost layer of the matrix material 3 is abraded after the winding process. Due to the fiber-free design of the radially outer region of the cover layer is achieved that even after repeated regrinding no fibers 4 reach the surface of the cover layer 2 and thus this surface has an optimal smoothness.
  • a dashed line 8 shows a division of the reference layer 2 into a radially outer functional layer 9 and a radially inner connecting layer 10 for connecting the functional layer 9 to the roller core 10.
  • Both the functional layer 9 and the connecting layer 10 consist of a matrix material 3, 3 'with fiber layers 7, 7' embedded therein, wherein preferably both the matrix material 3, 3 'and the fiber material forming the fiber layers 7, 7' are selected to be the same , In principle, however, it is possible to use different materials, if this better meets the desired requirements.
  • the fiber layers 7 'of the bonding layer 10 can be produced by winding fiber rovings and the fiber layers 7 of the functional layer 9 by winding a fiber fleece.
  • the fibers are usually unevenly distributed and shorter than is the case when winding fiber rovings.
  • the functional layer has a higher flexibility than would be the case with the use of fiber rovings.
  • the tensile strength and the thermal conductivity of the functional layer is improved by the use of a nonwoven fabric, for example, compared to the embodiment shown in FIG. 1, since the fibers of the nonwoven fabric are intimately engaged with each other.
  • the reference layer 9 may contain, for example, between 10 and 90, preferably between 40 and 50, fiber layers 7.
  • connection layer 10 usually has a lower thickness than the functional layer 9, due to the narrower arrangement of the fiber layers 7 ', the number of fiber layers 7' used can be similar to the number of fiber layers 7 of the functional layer 9.
  • a typical thickness for the bonding layer 10 is between 3 to 10 mm, while the functional layer 9 may have a thickness of 5 to 20 mm.
