In this storage space 30, the application medium 14 is distributed in the transverse direction Q, so that a sufficient amount of application medium 14 is always present on the doctor element 26 at every point in the working width. In addition, the pressure prevailing in the accumulated application medium 14 in the transverse direction Q is also equalized. Thus, the hydrodynamic pressure conditions are essentially the same at each point of the doctor rod 26, so that the application gap 32 between the substrate U and the doctor rod 26 is greater than that entire working width has a substantially constant width. The end result is the desired uniform application layer 12.

If the surface moves at a low speed, for example a speed of about 900 m / min, a long storage space with a small entry width should be used. At medium underground speeds, for example around 1000 m / min, both a medium storage space length and a medium entry width are recommended. In the event of high speeds of the subsurface, in particular speeds of more than 1500 m / min, a short stowage space with a large entry width should finally be used.
