Definitions

  • ABSTRACT A method of coating paper or other sheet material with surface layers by applying different coating compositions to each side of a travelling sheet by feeding the sheet between two opposed members defining a press nip formed of a resilient thin blade having a sharp edge engaging the sheet as one member of the press nip, and a rotatable roller supporting the sheet on one side as the other member of the press nip.
  • a first coating composition is applied to one side of the sheet from a dam defined on one side by the sheet and on the other side by the blade, whereas the second coating composition is applied to the opposed side of the sheet by means of contact transfer of said second coating composition, which has been previously applied to the surface of the roller.
  • the present invention intends to exploit the favourable effects of this known blade coating method, while avoiding the disadvantages in that this'known method does not permit coating with different coating compositions on opposite sides of the paper web.
  • a first coating composition is applied to the side of the sheet facing the blade from a dam defined on one side by the sheet and on the other side by the blade and a second coating composition is applied to the opposite side of the sheet abutting the roller by means of contact transfer of said second coating composition, which has been previously applied to the surface of the roller.
  • FIG. 1 shows a prior art device according to US. Pat. No. 3,489,592
  • FIG. 2 shows a paper guide roller 10, over which the paper web 4b is led generally downwardly towards the coating means.
  • the paper web meets the roller 1 at a point 9, this point lying above the horizontal surface of the coating composition in the dam l 1 which is formed between the blade 3 in the holder 2 and the rollersurface l.
  • the paper web is drawn over the blade edge 3 at an obtuse angle with respect to the roller radius at the point of contact of the blade with the roller.
  • a second rotating roller 6 is pressed with a suitable pressure against the roller 1.
  • a device 7 sprays the desired second coating composition onto the roller 6 which distributes and transfers a certain amount of the composition onto the roller surface 1.
  • the side of the paper facing away from the roller 1 is coated with a first coating composition in the dam 1 l in conventional manner, i.e. the blade 3 doses and smoothes out the coating composition on this side of the paper.
