ABSTRACT:
A spreading device for the coating of moving material webs, especially paper or cardboard includes a clamping mechanism adapted to alternatively hold a doctor rod support bed or a coating blade, a pressing tube for pressing a doctor rod mounted on the doctor rod support bed onto a counter roll or a material web guided by a counter roll, and a profile strip having a tip portion adapted to press against a coating blade, the profile strip movable in a direction transverse to the counter roll by a displacement device. A plane defined by a pressing force through a contact region of the pressing tube and the doctor rod support bed and a plane defined by a pressing force through a contact region of the profile strip and the coating blade are disposed transversely with respect to a length of the counter roll and are either parallel or disposed at an acute angle to one another.
