Definitions

  • the invention relates to a method for smoothing a paper or cardboard web.
  • the aim of the invention is a method for smoothing a paper or cardboard web, at which is still a wet track, without having previously made an asymmetrical one To have to generate moisture profile with respect to the web thickness, as desired can be smoothed.
  • the use of pressure and temperature during the Smoothing process must be clear and easy to regulate.
  • the smoothing process is particularly clear and controllable as desired shape.
  • a relatively low pressure is used in the long smoothing zone via the support elements can be in places of higher basis weight of the paper or cardboard web Pressure peaks largely avoided and better product quality achieved. It can due to the relatively long smoothing zone and sufficiently long dwell time of the material in the smoothing zone and thus the desired smoothness values on both sides of the web higher web speeds can be achieved. Especially the application lower pressures and high temperatures of the contact surfaces with higher web moisture levels favor smoothing that is gentle on the volume of the web, what is wanted here.
  • Paper or cardboard web 1 takes place in at least one smoothing zone 2 at one defined duration of the smoothing process.
  • the material is in the smoothing zone 2 during a dwell time, which is the length of the smoothing zone 2 and the Web speed can be calculated.
  • the material to be smoothed i.e. the paper or Cardboard web exposed to an adjustable pressure in the smoothing zone 2.
  • the pressure can be relatively low.
  • About the surfaces 3 and 4 arranged on both sides of the web 1 are used Temperature, which together with the moisture of the web 1 to the desired smoothing the train leads.
  • the conditions can advantageously be chosen so that none overpressed areas in a web of uneven basis weight. This happens in the extended smoothing zone 2, which is long enough to have one in it sufficient dwell time of the material in view of the to be driven To achieve web speed.
  • the smoothing zone 2 must be so long that the desired one Smoothing process completed during the dwell time and the desired smoothness reached can be. The higher the web running speed should be, the longer it has to be generally the length of the smoothing zone can be designed.
  • a device which is shown schematically in various figures as an example shown versions is used to carry out the invention Procedure.
  • the device has a smoothing zone 2, which is between two to each other facing surfaces 3 and 4 is formed.
  • the surfaces 3 and 4 run towards each other parallel, are heated and adjustable to each other, so that the web 1 a defined Pressing pressure can be exposed.
  • the areas 3 and 4 extend over a Longitudinal section in the direction of web travel, which is indicated by an arrow.
  • a flexible belt 19 can also be used, which is guided in a known manner, not shown here, over rolling rollers and in the Smoothing zone 2 is formed into a convex shape by means of a support element 18.
  • the convex support surface is complementary to the opposite arranged concave surface of the support element 8.
  • a e.g. Induction heating for that Volume 19 is indicated in Fig. 1 and designated 20.
  • Another usable Device, e.g. for heating with steam or hot air is also indicated in Fig. 1 and designated 21. This would particularly advantageously be used if it was a non-metal tape 19.
  • the pressure to be applied in the smoothing zone 2 is determined by adjusting the pressure in the Pressure medium of the support element 8 or the support elements 8 and 18 can be generated.
  • the Surface temperature of the smoothing surface is by means of devices 20 and 21, respectively adjustable.
  • the moisture is given by the moisture of the web 1 to be treated.
  • the flexible tapes are tight, i.e. impermeable, and between the tape and the A support layer of the support element is provided, which is a liquid layer is built hydrostatic and / or hydrodynamic manner. It takes care of low-friction running of the belt along the support surfaces.
  • the liquid could Heating and temperature control for cooling.
  • the support elements can in themselves be known sliding shoes, with a liquid between the support surface and the Tape was introduced.
  • the support elements can also be known hydrostatic Be support elements.
  • the bands are supported by mutually adjustable support elements 9, see FIGS. 2 and 4, supported, each facing a flat band 7 Have support surface. They can be pressed against one another in a known manner in a defined manner. Although hydrostatic support elements are drawn here, sliding shoes are also from known type applicable. Between each band 7 and the flat support surface of the Support element 9, a liquid layer is provided, which in the example according to FIG. 2 is built hydrostatically. For this purpose, the support element faces the band 7 Pressure pockets 23, which can be acted upon with a pressure medium, if necessary tempered for heating or cooling. It is also possible to apply the liquid layer to build hydrodynamic ways, such as in Fig. 3 on the surface 3 be the case could.
