Abstract

The invention relates to an inking mechanism for letterpress and offset printing machines comprising a vibrator having a plurality of discs which are disposed side by side and which are adapted to reciprocate individually and independently of one another between a duct roller and a transfer roller, and the width of each of which corresponds to a specific inking zone. The disc each consist of a middle part and an outer ring with a covering and are disposed side by side without gaps on a stationary carrier tube. Each middle part is mounted movably on the carrier tubes and has a circular outer periphery on which the outer ring is rotatably mounted and a drive for the individual movement of the middle part is provided inside each disc.
