  • Method of controlling the drive transporting a paper web in a printing machine
    Patent number: 6213367
    Abstract: A method of controlling the drive of the electric pretensioning unit of rotary printing machines having individually driven rotary printing cylinders and folders is specified, so that, in the event of changes being made to the paper grade or to the production sequence without the machine being stopped, only slight web tension changes occur, and the operating limits with regard to web tension are reliably maintained. This method is equally well suited to rotary printing machines having individually driven printing units or printing bridges and folders and to conventional printing machines that are driven by mechanical shafts via couplings.

  • Method for self-adjusting color and cut register control in rotary printing machines having a plurality of webs
    Patent number: 6092466
    Abstract: A method for self-adjusting color and cut register control in rotary printing machines having individual or a plurality of webs is specified, according to which the amount of relative web stretching of the individual web sections is calculated from the operating points of the drives driving the web and the correcting variables for color and cut registers are derived from the production-dependent combination of all the stretching values.

  • Method of operating a drive system and device for carrying out the method
    Patent number: 5988846
    Abstract: A drive system and a method of operating such a system are specified. The drive system comprises at least two drive groups having a plurality of drive controllers of controlled drives. The drive controllers of a drive group are synchronized via a drive bus by means of a local synchronization clock, and the local synchronization clocks are made equal to a global synchronization clock via a drive data network connecting the drive control means. The plant-wide synchronization of the drives via a global signal enables a drive system to be equipped with a virtually arbitrary number of drives. As a result of the fact that the desired values are preferably likewise transmitted synchronously, based on the global synchronization clock, between the drive control means via the drive data network, it is also the case that no time errors occur during the desired value transmission. The invention is preferably used for rotary printing machines.
