An arrangement for a chambered doctor blade (1) included in a printing unit having a rotatable cylinder (5) comprises a first force means (8) for applying the doctor blade (1) against the cylinder (5) in an operative position and a second adjustable force means (9) adapted to absorb at least part of a force generated by the first force means (8). The second force means (9) is automatically adjustable to allow the chambered doctor blade (1) to be moved towards the cylinder (5) in said operative position. A chambered doctor blade comprises at least one such arrangement for obtaining automatic displacement of the chambered doctor blade (1) relative to the cylinder (5) for the purpose of compensating for any wear on the wiping blades of the chambered doctor blade (1). <IMAGE>
