  • Method and system for improved sheet running control in a sheet-fed printing machine
    Patent number: 11427020
    Abstract: A method for computer-aided sheet running control in a sheet-fed printing machine includes, during a printing operation, using a measuring sensor to detect a printed sheet in the printing machine and using an activation sensor to initiate measuring performed by the measuring sensor by emitting an activation signal. The activation sensor is mechanically fixedly installed without adjustment, and temporal deviations of the activation signal are determined and compensated. A system for computer-aided sheet running control in a sheet-fed printing machine is also provided.
    Type: Grant

  • Device for detecting a position of a printing material transported in a printing machine
    Patent number: 10328725
    Abstract: A device detects at least one position of at least a part of a printing material while the printing material is transported in a printing machine. The device includes an optical sensor for establishing a distance between a printing machine component and the printing material. The distance established by the optical sensor is temperature-compensated by a computer.

  • Sheet-fed printing press with a sensor system and methods for calibrating and for aligning the sensor system
    Patent number: 10131137
    Abstract: A sheet-fed printing press includes a printing cylinder and a high-precision sensor system for monitoring a sheet run in the area of the printing cylinder. At least one gage, which is mounted on the printing cylinder, can be detected by the sensor system. It is particularly advantageous if the sensor system is configured to be self-calibrating. A method for calibrating a sensor system and a method for aligning a sensor system are also provided.
