摘要

The invention relates to a method for operating an application apparatus (1) for applying liquid to pasty application media (A1, An, An-1) in the form of at least one free-falling curtain (14) to a fibrous web (F) having an application head (2) which has at least one distribution chamber (4.1, 4.n, 4.n-1) and having an application-medium supply system (9) which is assigned to the application head (2). The invention is distinguished by the fact that, in the starting-up phase of the application apparatus (1), the application head (2) is operated with a fluid which is different from application medium (A1, An, An-1), in particular water. Furthermore, the invention relates to an application apparatus (1).
