- the elements delimiting the storage chamber are rigid with the device Squeegee beam connected, so that a change in position of the squeegee beam Optimization of the storage chamber shape suitable for the respective surface and size is associated with considerable effort.
- An application device with an underground inlet side by a Gap and chamber on the outlet outlet side delimited by a doctor blade is known from US 4,859,507 A.
- the chamber shown there is not completely filled with order medium during order operation. Rather, it is designed so that when the order is addressed to the Chamber walls against the direction of travel of the substrate to the chamber entrance bordering gap forms flowing application medium film.
- the application medium film occurs at the chamber entry gap against that of the application medium carried into the chamber and flowing into the chamber and leads to additional moistening of the surface and to smooth the damp application layer on the surface.
- this chamber is rigidly connected to the squeegee beam, so here too the above disadvantages occur.
- An application device is known from EP 0 319 503 B1, in which the application medium supply mainly between the storage chamber delimiting elements takes place, and in which in the one Doctor blade formed baffle entry restriction passages are provided, through which in excess introduced into the storage chamber Application medium against the direction of the substrate from the Stowage chamber can escape or in which in the direction of travel of the ground an additional one in front of the storage chamber inlet limiting element Order medium supply is provided.
