Definitions

  • Figure 1 shows an example in principle of a coating device 21 viewed from the side.
  • the device 21 comprises two rotating application rolls 22, 11, which are adapted in a nip contact and between which the paper or board web 24 to be treated, in other words to be surface sized or coated, is adapted to travel.
  • the direction of travel of the web 24 is indicated by an arrow, and the direction of travel of the rolls 22, 11 is also indicated by an arrow.
  • a web 24 treatment substance such as a coating mixture or surface sizing agent, is spread onto the surfaces 22', 11' of the application rolls 22, 11 by means of coating applicators 25.
  • FIG 2 shows one example of a disclosed but not claimed coating applicator 25 seen from the side.
  • the coating applicator 25 is constructed to rest on the girder 12, and the application chamber 20 that is against the application roll 11 is formed by a space in the girder 12, which space is limited in the direction of rotation of the application roll 11 by a sealing blade 10 which comes first, i.e. on the inlet side, and by a metering rod 15 which is on the outlet side, i.e. latter in the direction of rotation.
  • the sealing blade 10 is fastened to the girder 12 by means of a blade holder 17, and the metering rod 15 is fastened by means of a rod holder 14.
  • the moving surface 11' does not block the flow openings 34, 34.1 - 34.3.
  • This also ensures the functioning of the flow openings 34, 34.1 - 34.3 in all circumstances, in other words the access of air into the chamber 20 is prevented, the lubrication of the sealing blade 10 is ensured and the removal of overpressure from the chamber 20 is ensured.
  • the location of the flow openings 34, 34.1 - 34.3 on the flat 32 of the blade 10 may be optimized for example close to a standardized contact surface 33 and hence the lubrication between for example the blade 10 and the moving surface 11' may be intensified.
