Abstract of the Disclosure. A doctor device for the washing inking unit of a rotary printing press consists of a doctor carrier on which two doctor blades are attached which are parallel to each other and are able to be put into engagement with an inking roller and which together with the inking roll, the doctor carrier and sealing means provided at the end thereof define a sealed ink chamber. The ink is supplied to and removed from the ink chamber through ducts. The doctor carrier is able to be brought into engagement with the inking roller by setting means. In order to ensure that no ink is able to escape from the ink chamber even when the doctor device oscillates, the sealing means consist of moldings (19) or elastic or elastomeric material, which on their side facing the inking roller have dihedral downwardly sloping surfaces (20 and 21) for the end parts of the doctor blades and between the same a curved sealing surface (26) with the shape of a cylindrical shell able to be brought into engagement with the inking roll, said sealing surface have a radius of curvature corresponding to the inking roller (figure 5).
