  • Method of aligning a printing plate against a stop
    Patent number: 7730836
    Abstract: A reliable method of aligning a printing plate against a stop includes moving the printing plate and the stop relative to each other, detecting temperature changes occurring at a temperature sensor connected to the stop, when the printing plate comes into contact with the stop, deriving signals indicating the position of the printing plate relative to the stop from the signals of the temperature sensor, and deriving a signal indicating the thermal conductivity between the printing plate and the stop from a speed of change of the temperature sensor signal. A signal indicating incorrect alignment of the printing plate against the stop is output if the thermal conductivity drops below a predetermined threshold.

  • Apparatus for conveying a sheet through a printing machine
    Patent number: 7478806
    Abstract: An apparatus for conveying sheets through a printing machine allows continuous monitoring of the position of a sheet with regard to a guide element over a long time period. There is provided a circulating conveyor element with grippers in which the sheet is held at a leading edge. A device for setting the position of the sheet can adjust the position with regard to a desired position. A measuring configuration measures the position and the presence of the sheet. A control device is connected to the device for setting the position and to the measuring configuration. The measuring configuration is mounted so as to circulate with the conveyor element.
