ABSTRACT OF THE DISCLOSURE The invention relates to an ink feeding device for the ink-roll mechanism of a rotary printing machine with a duct-roller and a transfer roller cooperating not only with the duct roller but also with one of the inking unit rollers. The transfer roller is mounted upon its control shaft with play over its entire length. The surface of the transfer roller is of closed design. The body of the transfer roller is designed to flex at right angles to its axis of rotation. Means are provided to ensure that the transfer roller is pressed over its entire length snugly against both the duct roller and the inking unit roller. These means may be dispensed with if the weight of the transfer roller ensures that the surface thereof is pressed snugly against the two adjacent rollers. Extremely thin films of ink can be transferred continuously since by reason of its resiliency and its special mounting, the transfer roller is fully adapted to the shape of the surfaces of the two adjacent rollers.
