    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 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.
