A spray bar (1) provided with nozzles (2) is intended for spraying an ink removing solvent on an inking roller in a printing press. The nozzles are shielded off from ink mist and other contaminants except when solvent is to be sprayed. Practically, a cover (3) provided with openings (4) corresponding to the nozzles on the spray bar is slidably arranged on the spray bar over the nozzles so as to be movable between a first position, in which the nozzles can spray through the openings, and a second position, in which the nozzles are covered. <IMAGE> |
