  • Method and device for controlling the drive units in a printing machine
    Patent number: 7040233
    Abstract: A method and a device for controlling drive units in a printing machine are disclosed. During continuous production, and in anticipation of a foreseeable disruption, one or more measuring values that are suitable for characterizing the disruption, are determined. The measuring values are used to estimate the expected variations caused by the disruptions in the variables affecting the printing process. The variables are preregulated or precontrolled directly before the start of the disruption or during the disruption.
    Type: Grant
    Filed: July 11, 2002
    Date of Patent: May 9, 2006
    Assignee: Koenig & Bauer Aktiengesellschaft
    Inventor: Rüdiger Karl Seyfried

  • Method of regulating a web tension
    Patent number: 6211968
    Abstract: A process for adjusting a web tension in a web-fed rotary printing machine addresses the problems of processing variables which are not precisely quatifiable, while minimizing the influence of the press operator. This is achieved by adjusting the web tension using rules of fuzzy logic.

  • Electric motor speed control
    Patent number: 5787806
    Abstract: A speed control device for a multi-motor drive mechanism for driving printing press components is described. The speed control device allows the control of drive motors experiencing different instantaneous loads. This is achieved in accordance with the invention by assigning the motor having the greatest load fluctuation as the master, with the other motors assigned as slaves. A signal indicative of the demand experienced by the master is smoothed and used to control the slave motors.
