    摘要: For the active compensation of oscillations in a machine which processes printing material, a signal which contains an oscillation of the machine or of a part of the machine is measured and at least one counter torque is introduced into the machine to reduce the oscillation. At least one measure for a ratio between the amplitude of the uncompensated oscillation and the amplitude of the counter torque necessary for complete compensation is compared with a threshold value. The counter torque is determined in a first functional relationship with the oscillation if the measure is greater than the threshold value, and the counter torque is determined in a second functional relationship with the oscillation, if the measure is smaller than the threshold value. In the machine, a regulating device is operated in a first or second operating mode in dependence on the measure of the ratio.

    摘要: In a method for compensating an oscillation which has a frequency spectrum with a number of discrete frequency components in a printing press, at least one counter torque is introduced into the printing press in order to compensate for at least one discrete frequency component of the oscillation. A first group of one or more frequency components are compensated for by introducing one or more previously determined counter torques, and a second group of one or more frequency components is compensated for by introducing specific counter torques as a function of a measurement, carried out during the operation of the printing press, of at least one signal which contains at least the one or the plurality of frequency components.

    摘要: A multi-motor drive for a printing press having a plurality of printing unit groups, includes at least one motor provided for each of the printing unit groups, and gear trains via which the printing unit groups are synchronously driven. The gear trains are mechanically separated from one another during a printing operation. The at least one motor is assigned to a respective separation location between the printing unit groups. A method for driving a printing press is also provided.

    摘要: A process provides for the safe operation of a printing machine. The printing machine has a first cylinder driven by a first motor, and a second cylinder driven by a second motor. The first cylinder accepts sheets of paper from the second cylinder or delivers them to the second cylinder by a gripper system. In the case of a deviation in the synchronized running between the cylinders, the gripper system is retracted at least in part far enough into the first cylinder that the possibility of a collision of the gripper system with the second cylinder is eliminated.

    摘要: A method and apparatus for separating at least two bridges, especially gripper bars, of a segmented transport system for printing materials, e.g. sheets of paper in a printing press, include a transport system having a segmented electric linear drive with first and second primary parts constructed as segmented long-stator. The drive has a plurality of secondary parts constructed as carriages. Each secondary part assigned to the first primary part and each secondary part assigned to the second primary part are coupled by a crossmember to form a movable bridge. Two bridges in the same segment are moved jointly. A first bridge, reaching into a further segment due to jointly controlled movement, is moved individually under closed-loop control and separated from a second bridge, for locating the two bridges in different segments during further movement. Electrical and mechanical collisions of the bridges or of the carriages can therefore be eliminated.
