Definitions

  • the invention relates to a device for applying one or both sides of several liquid or pasty application media on a running surface, comprising a Curtain applicator with a nozzle for applying the application media, the Curtain contracting the order media as essentially Gravity-related moving curtain delivers to the running surface, and the Surface for direct application, the surface of a material web, in particular from Paper or cardboard, and for indirect application the surface of a Transmission element, preferably an applicator roll, which is the Apply media to the surface of the web
  • the invention has the object of a device of the type mentioned in that it is possible to have several or different ones Coatings along the width of a material web to be coated applied.
  • the invention solves the problem by a device of the beginning mentioned type, according to the invention with the curtain applicator with a nozzle several juxtaposed along the width of the running surface Chambers is equipped.
  • the curtain applicator with a nozzle several juxtaposed along the width of the running surface Chambers is equipped.
  • several chambers along the Width of the running surface can be several coatings on one too coating material web along the width are applied.
  • This can be job media with different properties or rheological behavior or different types of liquid or pasty Be order media.
  • the chambers may be fixed Partition walls to be equipped.
  • the partitions avoid mixing the Application media in the nozzle. Since the partitions are fixed, always can Coatings of the same width can be applied next to each other.
  • the chambers can be moved with Partition walls to be equipped. This is the width of the coatings adjustable according to certain specifications. In this way, the Device can be flexibly adapted to specific requirements.
  • the partitions have a tapered End area on.
  • the tapered end areas give the side by side arranged application media in the gravitational down moving Curtain a guide in the downward movement. They also allow one turbulence-free connection of the mutually contacting application media.
  • the partitions can over the outlet openings of the nozzle protrude.
  • Another embodiment has short partitions, in front of the Exit the nozzle outlet. Consequently, the order media leave within the Nozzle the chambers and thus come into contact with each other in the nozzle. Because the However, application media can come into contact with each other within the nozzle no thickening forms at the contact areas of the application media, such as this would be the case if the application media come into contact outside the nozzle would. Because the unwanted thickening due to the relatively short partition be avoided, have the applied on the web application media in their contact area also no thickening, so that the Coating thickness is even on the material web.
  • baffle At the nozzle can also be mounted a baffle over which the application media can flow.
  • the baffle supports a connection of the side by side from the Nozzle escaping application media. However, order media does not mix, they should have the highest possible viscosity.
  • Fig. 1 shows a nozzle 10 of a curtain applicator.
  • the nozzle 10 is divided into three chambers 11, 12 and 13. Through the three chambers 11, 12 and 13 of a material web three different application media 17, 18 and 19 are fed. Since the chambers 11, 12 and 13 are arranged side by side along the width of the material web to be coated, the three different application media 17, 18 and 19 are applied side by side on the material web. Thus, it is possible, for example, to apply three different coating media side by side on the material web.
  • the chambers 11, 12 and 13 are separated by partitions 14 and 15 from each other.
  • the partitions 14 and 15 have a tapered end portion 16.
  • the tapered end portions 16 give the adjacently arranged application media 17, 18 and 19 in the gravity-down moving curtain a guide in the downward movement. They also allow a turbulence-free connection of the mutually contacting application media 17, 18 and 19.
  • the partitions 14 and 15 are fixed, and thus allow always coatings of the same width can be applied to the material web side by side.
  • FIG. 2 shows a nozzle 20. It has three chambers 21, 22 and 23, so that the three application media 17, 18 and 19 can be applied to the material web.
  • the three chambers 21, 22 and 23 are separated by two movable partitions 24 and 25. Since the two partitions 24 and 25, as indicated by small double arrows, are displaced, the width of the coatings can be adjusted according to certain specifications.
  • the nozzle 20 can be adapted by the displaceability of the partitions 24 and 25 flexibly to certain requirements.
  • the partition walls 24 and 25 have a tapered end portion 27 which protrudes from the nozzle 20 and from the outlet opening (outlet slit) 34. Due to the protruding partitions 24 and 25 is given to the gravity down moving curtain 29 or the three from the three chambers 21,22, 23 running curtains 29a, 29b, and 29c or even more curtains even better guidance.
  • FIG. 3 shows a nozzle 30 which has two chambers 31 and 32.
  • a partition wall 33 separates the two chambers 31 and 32 from each other.
  • the partition wall 33 is relatively short and ends even before an outlet openings 34 of the nozzle 30. Therefore, application media 35 and 36 leave the chambers 31 and 32 already within the nozzle 30.
  • the application media 35 and 36 come thus already within the nozzle 30 in contact. Since the application media 35 and 36 come into contact with each other within the nozzle 30, no thickening may form in contact areas of the application media 35 and 36, as would be the case if the application media outside the nozzle 30 were to come into contact. Since the unwanted thickening is avoided by the relatively short partition wall 33, and the application media applied to the material web 35 and 36 in their contact area no thickening, so that the coating thickness is seen on the material web over its width is very uniform.
  • Fig. 4. shows a nozzle 40 to which a baffle 41 is mounted.
  • the baffle 41 supports a flow of the exit media across the downward flow forming the curtain.
  • the application media exiting side by side from the nozzle 40 can connect better.
  • the intended application media should have the highest possible viscosity.
