Definitions

  • the invention relates to a device for coating sheet-like materials with a coating medium.
  • the coating media are masses such as dyes, dye dispersions or adhesives.
  • Modern coating devices in particular printing machines, use closed chamber doctor blade systems. Devices with open ink pans and dipping rollers can only be used for low coating speeds. Only through the use of chamber doctoring devices was it possible to achieve a correct and uniform coloring of the transfer rollers at greater production speeds.
  • Such a device is in the European patent specification EP 1 117 488 B disclosed.
  • This coating device describes the application of an adhesive to a continuously transported web. The adhesive is transferred to the web through a line-engraved or also well-engraved roll.
  • the roller has, for example, on its circumference a helically arranged engraving groove.
  • the adhesive is applied by a gun on the circumference of the gravure roll.
  • the applicator has a main chamber for the coating medium.
  • the main chamber is covered by the lateral surface of the transfer roller and limited in the direction of movement of the transfer roller rear gap between the lateral surface and the main chamber by a doctor which sealingly abuts the lateral surface of the transfer roller.
  • the forward gap in the direction of movement of the transfer roller between the lateral surface and the main chamber is limited by a flowing out of a nozzle high-speed medium flow and additionally by a seal. This high-speed media flow exits the nozzle, which extends over the entire width of the transfer roller, counter to the direction of movement of the transfer roller.
  • a preferred variant of the applicator device has a spring-mounted nozzle, as a result of which the drainage surface of the coating material discharged from the nozzle is set free. This ensures that no additional pressure on the seal acts on the main chamber. The result is a minimal coating media flow from the nozzle side into the main chamber, which is determined only by the engraving depth.
  • the application weight is determined solely by the conditions in the main chamber.

Dispositif selon la revendication 1, caractérisé en ce que le sens d'écoulement du flux de fluide à haute vitesse (7) est réglé de sorte à permettre - en même temps que l'obturation de l'interstice (16, 16') de la chambre principale (12) relativement à la pénétration d'air et à la sortie du fluide d'enduction - l'enlèvement le plus intense possible de résidus de fluide de revêtement (6) présents dans les creux (4") du rouleau de transfert (3).
  6. Dispositif selon la revendication 4, caractérisé en ce que le sens d'écoulement du flux de fluide à haute vitesse (7) est réglé de manière à permettre - en même temps que l'obturation de l'interstice (16, 16') de la chambre principale (12) relativement à la pénétration d'air et à la sortie du fluide d'enduction - l'enlèvement de résidus de fluide de revêtement (6) présents dans les creux (4") du rouleau de transfert (3) et un remplissage des creux (4"').
