1. A device for applying a free-flowing medium to a continuously transported web, comprising:
a continuously rotating transfer roll formed as a gravure cylinder provided with gravure grooves on its circumference;
an applicator head provided to transfer the free-flowing medium to the circumference of the gravure cylinder, the applicator head having a chamber open toward the circumference of the gravure cylinder with an inlet and an outlet for the medium to be applied;
a front doctor blade arranged to bound an outer side of the chamber at a front with respect to a direction of rotation;
a rear doctor blade arranged to bound the outer side of the chamber at a rear with respect to the direction of rotation, both doctor blades resting with a sealing action on the circumference of the gravure cylinder; and
a pressing body arranged to press the front doctor blade against the circumference of the gravure cylinder with an adjustable pressing force so as to change pressure in the chamber and thereby influence an amount of the medium flowing past the rear doctor blade,
wherein the pressing body determines a width of a two-dimensional contact zone of the front doctor blade with the gravure cylinder.
