Definitions

  • Machine for producing and treating a material web with an application device having at least one contactless application unit
  • the invention relates to a machine for producing and treating a material web, preferably made of paper or cardboard, at least comprising: a material web forming device which is designed to continuously form a material web from supplied starting material, preferably from a fiber suspension; a dewatering and drying section arranged along a material web path after the material web forming device, which is designed to remove water from the running material web at least by thermal and / or mechanical action and to dry the material web at least to a residual moisture content; at least one application device arranged along the material web path after the dewatering and drying section for applying liquid or pasty application medium to at least one side of the running material web; a drying device arranged along the material web path after the application device for drying the running material web to a final drying state; a device arranged along the material web path after the drying device for processing or / and picking up and / or delivering the material web, preferably a material web winding device for rolling up the material web onto a respective material web roll.
  • offline operation has a lower volume efficiency.
  • the object of the invention is to improve the performance or runnability of the machine mentioned at the outset without having to accept the loss in quantity of the offline concept.
  • the application device comprises at least one contactless application unit which is designed to dispense application medium in at least one free application medium jet or application medium curtain or application medium veil or in application medium spray drops and to apply it to the material web Basis of the forces or / and movement impulses given by the application medium and / or on the basis of a movement of the application medium caused by gravity.
  • an order based on electrostatic forces can be considered, for example.
  • contactless application of the application medium to at least one side of the material web in particular contactless (one-sided or double-sided) painting of the material web in online operation in the machine (in particular paper machine) is made possible.
  • contactless one-sided or double-sided
  • a so-called curtain coating method is preferably used.
  • At least one contactless application unit designed as a curtain application unit which delivers the application medium to the material web in the form of at least one curtain or veil, preferably at least predominantly on the basis of a movement of the application medium due to gravity.
  • a so-called spray coating process could also be used.
