Abstract of the Disclosure The invention relates to a coating device for coating moving webs of material, more particularly webs of paper or board, comprising a belt or hose (7), which is trained about the curved guide surface of a beam- or rod-like support member (1) and a drive roll (6), a cooperating roll (C) carrying the web, a coating gap (9) being defined between the cooperating roll (C) and the hose (7) for the application of the coating material to the web or the roll, a support beam (3), which extends in parallelism to the roll and the drive roll (6), for supporting the support member (1), and between the same a pressure hose (4) for the transmission of the support forces. The invention is characterized in that the support member (1) possesses a rib- or rail-like extension in its part remote from the curved guide surface at the gap (9), on which there acts a further pressure hose (5 and 5') arranged between a corresponding support surface on the support beam (3) and the extension of the support member (1), essentially in a direction which is transverse in relation to the direction of action of the first pressure hose (4 and 4'), the first pressure hose (4 and 4') being arranged essentially at the free end of the extension (2 and 2') of the support member (1 and 1').
