Abstract
A ductor or film-transferring inking mechanism for printing machine, particularly for offset presses, which comprise a plate cylinder having a printing form, an ink reservoir and a ductor roller mounted for rotation so as to dip into the ink reservoir and at least one additional rotatable distributor roller engageable between the ductor roller and the plate cylinder. A rotatable takeoff roller is associated with one of the distributor rollers of the inking mechanism and is adapted to engage with one of these rollers and take up the periodically unused and no longer applicable ink from this roller and to be moved to a position so as to be engageable with a stripper roller so as to transfer this ink to the stripping roller. A stripper such as a ductor blade is engaged with the surface of the stripper roller and it strips the ink therefrom and permits it to return into either a separate container or directly back into the ink reservoir.
