摘要： The control device for a suction gripper on a guiding cylinder of a sheet fed rotary press comprises a tumbler shaft mounted on the sheet guiding cylinder and a suction unit swingable about a pivot point which is supported for movement about the tumbler shaft. The suction unit is either positively driven by a cam drive or self-adjustable by means of a tension spring between the unit and the tumbler shaft.

摘要： The invention relates to a method of compensating for register deviations, which enables printing quality-reducing register deviations to be avoided at all printing or coating units of a rotary printing press. The method includes: a one-time determination of rotational vibrations in the driving gear train and of thereby caused register deviations between the printing or coating units only in the resonance regions of rotational speed under printing conditions within a rotary printing speed range; ascertaining counter-directed harmonic compensation moments from discrete harmonic portions of the rotational vibrations in the resonance range of rotational speeds; storing the parameters of the harmonic compensation moments and assigning them to the resonance ranges of rotational speed in the driving control system; and superimposing the stored compensation moments as a function of the rotational speed on the driving moment of the main drive motor in printing operation.

摘要： The invention relates to a method of compensating for register deviations, caused by rotational vibrations, in a sheet-fed rotary printing press with a driving gear train, connecting a sheet-feeding apparatus and printing units and/or coating units, and a main drive motor, acting on the driving gear train, to which a drive control is assigned. It is an object of the invention to configure a method, which reduces rotational vibration-induced register deviations and, with the least effort, enables printing quality-reducing register deviations to be avoided at all printing or coating units of a rotary printing press by a process with the following steps: single determination of rotational vibrations in the driving gear train and of thereby caused register deviations between the printing or coating units in the resonance regions of rotational speed under printing conditions within a rotary printing speed range, ascertaining counter-directed harmonic compensation moments from discrete harmonic portions of the rotational vibrations in the resonance range of rotational speeds, storing the parameters of the harmonic compensation moments and assigning them to the resonance ranges of rotational speed in the driving control system and superimposing the stored compensation moments as a function of the rotational speed on the driving moment of the main drive motor in printing operation.
