摘要

Inking system of a printing machine for the colouring of a forme cylinder (07), which has a roller train with at least two distributing cylinders (12.1, 12.2), namely a form cylinder the near and at least one the form of cylinder more remote end of the distributor cylinder (12.1, 12.2), and wherein one of the distributing cylinder (12.1) only in rotation by means of friction with adjacent rollers (11; 13) and another one of the distributing cylinder (12.2) to its rotatory drive a mechanical drive connection to a drive motor (18), characterized in that the drive motor (18) and an associated drive control (46) are designed in such a way that the drive motor (18) at least during a printing operation in pressure - to - position of the inking unit (08) not in the view of a fixed speed, but with respect to a predetermined power and / or of an adjustable torque is controlled or regulated is operated, that the drive motor (18) as a servomotor (18) is formed, and in that the drive motor (18) optionally in a first mode with respect to the specification of a rotational speed or a frequency and in a second mode with respect to the specification of a power or as a rule, a torque-..
