ABSTRACT:
An application unit for directly or indirectly applying a fluid or pasty medium to a continuous material web, particularly made of paper or cardboard, includes a support beam extending in its longitudinal direction substantially across the entire width of the material web; a counter-roll opposite the support beam; a doctor element detachably secured to the support beam via a holding device and extending substantially across the entire width of the counter-roll; and a pressing member disposed on the support beam and to which a pressing force is directly and/or indirectly applied by at least one pressing device and with which the doctor element can be pressed against the counter-roll at a predetermined pressure in the region of its blade-element end mated with the counter-roll. When viewed in cross section, the pressing member is formed as a parallelogram body supported at one end in or on at least one mount and running substantially parallel to the doctor element.
