    Abstract: In a method to damp an oscillation of a roller driven via a drive in a printing system, a printing substrate web is directed across the roller, the roller and the printing substrate web forming a system capable of vibrating. With the drive the roller is driven with a predetermined nominal moment. With a sensor, a real value is determined of a variable representative of a velocity with which the printing substrate web is transported by the roller. In aid of a predetermined calculation rule, a correction moment is calculated from the determined real value such that a damping of the vibration-capable system results like a mechanical viscous damper. The correction moment is added to the predetermined nominal moment upon activation of the drive.

    Abstract: According to a drive control method and apparatus, an offset printing section and an intaglio printing section are connected together by a gear train. Separately from an offset printing section prime motor for driving an entire sheet-fed printing press, an intaglio printing section auxiliary motor is provided in the intaglio printing section where load is heaviest and load variations are great. By so doing, the entire sheet-fed printing press is driven by the offset printing section prime motor and the intaglio printing section auxiliary motor. Moreover, the electric current value (driving torque value) of the intaglio printing section auxiliary motor is controlled in accordance with an electric current value (torque value) for driving the offset printing section prime motor, the torque distribution rate of the intaglio printing section auxiliary motor, and the rated electric current value of the intaglio printing section auxiliary motor.

    Abstract: A method for regulating a first printing unit is provided. The first printing unit includes a plate cylinder, a first blanket cylinder carrying a tubular blanket and an impression cylinder. The first blanket cylinder defines a region of contact with the plate cylinder. The impression cylinder defines a region of counter-pressure with the first blanket cylinder. The method includes when the first printing unit is printing, a regulating step of a duration greater than or equal to six minutes in respect of the angular printing velocity ω1 of the first blanket cylinder relative to the angular printing velocity ω2 of the plate cylinder so that, for at least part of the duration of the regulating step, the ratio ω1/ω2 of the angular velocities is different from the ratio D2/D 1 between the diameter D2 of the plate cylinder and the diameter D1 of the first blanket cylinder in order to define a difference in velocity Δω=ω1−ω2×D2/D1, any difference in velocity Δωbeing of the same sign throughout the entire duration of the regulating step.

    Abstract: The invention relates to a direct drive for a cylinder of a converting machine, in particular a printing press or coating machine that converts sheet-type printed materials. The aim of the invention is to develop a direct drive for a cylinder of the afore-mentioned type in such a way that the required lateral corrections are significantly reduced. To this end, the direct drive includes a rotor (14) that is detachably mounted on the end of the cylinder (6, 10) and a stator (15) that is concentric with the rotor and is detachably fixed to the side frame (13). A register motor (16), which is fixed to the frame, is coupled to gearing (17, 18) and this gearing (17, 18) is coupled to a helical gear or screw drive (19, 2, 21, 22), which is in turn coupled to the cylinder (6, 10) by means of an axial/rotative coupling (23, 24).
