Definitions

  • the invention relates to a device for applying liquid or pasty application medium, especially aqueous pigment suspension, on a running surface, including a curtain commission, which the application medium from a dispensing nozzle as in the Moving curtain or veil due to gravity delivers the surface, whereby the surface with the direct application Surface of a material web, in particular made of paper or cardboard, and with indirect application, the surface of a transfer element, preferably a transfer roller, which is then the application medium to the Surface of the material web transfers.

  • the application medium is applied to the substrate in the form of a Application medium curtain or curtain (for the sake of simplicity in the following only the term “order medium curtain” or only “Curtain” used), which is essentially due to gravity moved from the commissioned work to the underground. That this Curtain application work itself at a predetermined distance from Among other things, it has the advantage that it is located underground is at a lower risk of damage in the event of a web break.
  • the surface tension tries the curtain a very large one based on its volume or cross-sectional area Surface or circumferential length has to contract, so its Reduce surface area. Gravity opposes this effect, who tries to stretch the curtain. It is therefore easy to see that it the more difficult it is to get one evenly across the entire working width to get thick application medium curtain, the larger this working width is.
  • the coating of material webs by means of a curtain applicator, which feeds the application medium to the material medium as an application medium curtain that moves due to gravity, has long been known from the coating of photographic films, tapes and the like.
  • corresponding devices for applying a liquid film to a textile material web with the aid of an application medium curtain that moves due to gravity are known from the field of the textile industry, for example from DE 33 33 592 A1 and DE 40 15 946 A1.
  • the material webs in these fields of application have a considerably smaller width than is the case with modern systems for the production of paper and cardboard webs, in which material web widths of more than 10 m are required today.
  • the high web speeds also put a further high load on the stability of the application medium curtain, since the application medium curtain is not only stretched due to gravity in free fall (gravity stretching), but also when it comes into contact with the ground due to the difference between the speeds of the freely falling application medium shortly before it hits the surface and the running speed of the moving surface (Contact stretching).
  • No. 10024360 is a curtain applicator published in which an order fluid through two counter-rotating rollers are extracted from a reservoir, the application liquid being stretched into a thin film, and then essentially under the influence of gravity on you Surface is applied.
  • the effects mentioned have a stronger influence on the quality of the application medium curtain, the smaller the flow rate of the application medium delivered by the curtain application unit per meter of working width to the substrate, ie the thinner the application medium curtain.

  • the order medium curtain is most likely based on the fact that the application medium when it comes into contact with the guide element is slowed down, which stabilizes the shape of the application medium curtain.
  • the falling speed more precisely the flow speed, takes of the application medium along the guide element, again.
  • This stabilization of the application medium curtain according to the invention can determine the total fall height of the curtain and thus the total achievable gravity stretch compared to a conventional one free-falling application medium curtain without sacrificing the Quality of the application medium layer thus formed can be increased.
  • the words “lead along the fall path” in the Connection with the present invention also mean can that the application medium curtain through the guide element from the the path corresponding to the free fall can be deflected.

  • This "teapot effect” a characteristic deformation of that emerging from the dispensing nozzle Application medium curtain occurs in practice when the Flow rate of the application medium when leaving the Dispensing nozzle falls below a limit speed, which on the one hand of the physical properties of the application medium and the other depends on the thickness of the application medium curtain. Thin curtains also tend to the To show "teapot effect”.
  • Exceeds the Outflow velocity the limit mentioned above, a parabolic curve of the application medium curtain usually forms out.
