  • Method and apparatus for coating a carrier
    Patent number: 10994269
    Abstract: Disclosed is a method and a corresponding apparatus for coating open-pored bodies with at least one coating suspension, the coating suspension having solids and solutes in a liquid medium in a quantity in wet state which is to correspond to at least a required target quantity, and the coating operation having a variation in the applied wet coating quantity from one body to the other. The method includes steps of: coating the body with an actual quantity of the coating suspension, which is always larger than the required target quantity taking the variation of the coating operation into account, determining the difference between the actual quantity and the required target quantity, and reducing the difference between actual quantity and target quantity by removing still wet coating suspension.
