Definitions

  • the present invention relates to a method and a device for curtain coating a moving Carrier with a liquid coating material according to Preamble of claim 1.
  • This coating especially when the machine is wide and large Speed, there are a large number of Problems to stabilize the curtain and if possible to bring evenly on the surface.
  • FIG. 1 schematically shows part of a coating device shown as part of a system.
  • the foundry plates 1 see also Figure 4, with the side attached side boundary plates 2, which the Casting solution 3 is limited for the respective casting width.
  • the free begins at the lip 4 of the foundry front plate 5 Fall of the curtain. From this point on, the curtain 6 be stabilized by the side guides 7. Without these The curtains would be under the effect of the side guides Pull the surface tension towards the middle.
  • the coating device also assigns one coating carrier 8 on the casting roll 9 and is guided under the coating device.
  • Figure 1 the direction of rotation of the casting roll is also shown.
  • the page-limiting Liquid film no longer parallel to the casting solution, or to the curtain, but across it, that is, see in particular Figure 3, the liquid film 10 parallel to the flow-limiting front wall 7 ' Lateral guide 7 initiated, the liquid film 10 flows in a groove 14 in the side guide and part forms the front wall of the side guide.
  • the liquid for example water or a water / gelatin solution through a metering slot 11 inserted, the slot end 12 being shaped such that the liquid film 10 regularly and with uniform thickness the groove in the side guide flows down.
  • a knife 15 attached, the outer geometry is known per se.
  • this knife also points to flow separations to avoid a leading edge 16 on that a sharp one with respect to the inside of the side guide Forms angle ⁇ of 0-30 °, for example 10 °.
  • a suction slot 20 To the by the compressed curtain edge on the edge of the Avoiding suction knife formed bead is at the bottom edge of the knife arranged a suction slot 20, the connected to a vacuum system via a channel 21 which can be the same as for the suction slot 18.
  • This channel preferably also contains a water rinse. As shown in Figure 2, this creates an edge of Coating 22 that can be used without loss.
  • the knife height at the cutting edge 5 of the knife can be 1 - 15 mm amount and it is appropriate to use the suction slot from one Knife height of 3 mm to be used, while at a Knife height of 1 - 3 mm dispenses with a suction slot can be.
  • the delimiting edge 25 of the Side boundary plates is not vertical, but one Has cutting edge 24, which cutting edge has an angle of for example includes 60 °, which means that the two Edge of the cutting edge with the 22 perpendicular to the coating an angle ⁇ and ⁇ of 10 - 80 °, preferably 60 °, exhibit.
  • the distance H between the cutting edge is 24 and the surface of the foundry plates 0.3 - 2.5 mm, preferably 0.8 mm. This will make the effect of Surface tension is reduced to a minimum, and there will be lateral displacements of the casting solution largely avoided.
  • inventive Device can be varied with respect to the specified mass can and the most diverse coating conditions and Casting solution combinations can be adjusted. While every single measure already extensive improvements with regard to the quality of the coating results in a Combination of all improvements, such as Vacuuming the cut edges, vacuuming the at Knife jammed pouring solution as well as avoiding the Differences in layer thickness due to surface tension and guiding a thin film of liquid along the Side boundary plates a particularly stable Coating, the edges of which do not lose material or Cause more drying problems.
