Abstract: A movable lifter roller (6) used for transferring the ink from an inking roller (8) to a brayer roller (5) is subdivided into a number of sections (6'). Each lifter-roller section (6') is pivoted on a respective two-armed lever (22). All levers (22) are pivotably disposed on a common axle (28) in such a way that the lifter-roller sections (6') normally rest against the brayer roller (5) and, in the activated state for picking up ink, rest against the inking roller (8). After the return into the position previously assumed, the ink picked up is transferred to the brayer roller (5). For putting the lifter-roller sections (6') into the activated state, there is associated with each individual lifter-roller section a respective electromagnet (31) which a lug (30) of the lever (22) serves as an anchor. All electromagnets 31 are rigidly fastened to a stationary support (33).
