Definitions

  • the invention relates to a device for indirect application of a liquid or pasty medium on a running material web, in particular made of paper or cardboard, comprising a commissioned work for application a layer of the liquid or pasty medium on the surface of a Transfer elements, which is in contact with the running material web and transfers the application layer to it, and with a leveling device a leveling element adjustable against the material web for smoothing the order layer transferred to the material web.
  • Such application devices are for example from DE 43 02 435 A1 and DE 42 43 518 A1 are known.
  • these two publications disclosed application devices is the still wet application layer processed with the help of distribution rollers to the surface roughness of the Application layer that occurs when the material web is detached from the transfer element due to the so-called "film splitting" effect smooth.
  • these rubbing rollers are around its axis running in the transverse direction of the material web is driven in rotation and lead due to a further drive in the transverse direction of the material web oscillating movements.
  • the need to move the Combine the grinder rollers in accordance with two degrees of freedom of movement having to do leads to a problem with the known application devices structurally complex structure. They were used to employ the leveling facility against the material web required movement and The drive mechanism required to bring about this movement not considered.
  • the leveling element can, for example, be essentially a doctor bar include a smooth surface, which, if desired, is driven in rotation, i.e. can be a doctor blade stick.
  • the leveling element in the application layer substantially smoothes. In this way, returns or Preparation stations for removed application medium saved become.
  • the transfer element is a transfer roller is, and that the material web, the transfer roller at least over a part whose circumference wraps around.
  • the contact of the order medium with the Material web can also be improved in that on the Side of the material web facing away from the transfer element, a counter element, preferably a counter roll is provided, preferably the Line pressing force between transfer element and counter element between is about 5 kN / m and about 30 kN / m.
  • the device according to the invention can also be used on both sides Apply liquid or pasty medium.
  • the counter element as a further transfer element for indirect application of liquid or pasty medium is trained.
  • a further transfer element can be added Equalization device may be arranged downstream, preferably the two Equalizing elements mutually support the other for each other Form leveling element.
  • the application weight per side of the material web can be, for example, between approximately 3 g / m 2 to approximately 25 g / m 2 , preferably approximately 8 g / m 2 to approximately 16 g / m 2 .
  • the application medium can include mineral substances such as kaolin, calcium carbonate, titanium dioxide, and special organic additives, for example plastic pigments or capsules.
  • the solids content of the application medium is between about 20% and 70%, preferably between about 40% and 65%. The solids content is understood to mean the mass of the abovementioned solids based on the total mass of the application medium formed from solids and carrier fluid, for example water.
  • the paper coated with the application device according to the invention has, for example, a basis weight of between approximately 30 g / m 2 and approximately 500 g / m 2 .
  • the smoothing result also depends on the line pressure depends with which the leveling element against the material web is employed, as well as the running speed of the material web. Of the reason for this is that the width of the smoothing gap between the Material web surface and the leveling element in the interplay between the contact pressure of the leveling element and the pressure in front of the leveling element build-up hydrodynamic pressure of the application medium results.
  • an application device is generally 10 designated. It comprises a transfer roller 12, on the surface 12a by means of an application unit 14 a layer of liquid or pasty Medium 16 is applied.
  • the transfer roller 12 is about an axis A. rotatably arranged in the direction of arrow P. As a result of the rotation of the Transfer roller 12 becomes the application medium 16 in the direction of travel L moving around a part of the circumference of the transfer roller 12 Material web 18 fed.
