Definitions

  • the change of the contact pressure can be determined and the state of each individual knife can be determined.
  • a sensor determines the contact pressure of the printing device and transmits the value to a measuring device. By changing the pressure, the sharpness or damage of the knife blade can be accurately determined.
  • the change in the contact pressure of the pressure element or the printing device 7 is used to monitor the state of the knife 2, in particular the breakage of the knife 2.
  • a sensor 16 determines the actual contact pressure of the printing device 7, for example of the cylinder 8, and forwards the signal to a measuring device 18 which generates a signal 20 by means of a controller 19 or a controller if limit values are exceeded.
  • the controller 19 detects deviations from a target size, which then conclude whether a blade 2 is blunt or possibly broken with an even greater deviation.
