ABSTRACT:
An applicator device is provided, particularly for solvent-containing and solvent-free UV printing inks, paints or adhesives onto a pattern roller of a flexographic printing machine, which receives the medium in recesses and transfers same to a high pressure roller. To avoid the occurrence of air bubbles in the medium to be applied and to press air out of the emptied recesses before they are filled again, a housing adapted to the lengths of the pattern roller and a dosing roller with elastic surface is provided above the contact line between the dosing roller and the pattern roller, which creates a chamber for accepting the medium located above the contact line of the two rollers and seals the chamber at all sides in a gas and air-tight manner.
