A multi-axis robot includes robot drives, a tool head, a drag chain for guiding flexible lines along at least a part of the robot up to the tool head, and an auxiliary system for moving a tool head-side end of the drag chain. The auxiliary system includes at least one auxiliary system drive for moving the tool head-side end. The auxiliary system drive is different than the robot drives. The multi-axis robot advantageously allows collisions between the tool-side end of the drag chain and the object to be treated or other objects in the vicinity of the robot to be avoided, ensuring that the surface of the object may be treated, in particular printed on by an inkjet print head, without disruption.

A method for determining the optimum procedure for a job change on a printing-material processing machine () with at least one control computer. The data of a first machine job is compared to the data of a subsequent machine job using a control computer, and the comparison is used to establish an order of the operations to be carried out during the job change. Also provided is a device for determining the optimum procedure for a job change on a printing-material processing machine () with at least one control computer. The control computer is intended to compare the data of a first machine job to the data of a subsequent machine job, and to use the comparison to establish an order of the operations to be carried out during the job change.

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.

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.

A method of driving a machine related to printing technology, wherein movable elements forming a kinematic chain are coupled with one another via at least one gear mechanism, includes infeeding torque components by a respective motor of at least one group of two motors, respectively located at least at two elements associated with one another. The torque components are of equal amplitude but have opposite directions of rotation, for suppressing disruptive oscillations at least at the one group of two motors. The amplitude of the torque components is proportional to relative rotation of the two elements associated with one another. Rotary encoders are provided to obtain signals for reproducing rotational positions of the elements.
