  • the sensor 24.1 preferably has the same connections as a sensor 24.1, 24.2, 24.3 of a scroll rail 11, which enables easier assignment to the evaluation device.
  • the connection of a sensor 24.1, 24.2, 24.3 to the evaluation device can also take place automatically by inserting the respective lateral guide device on the base body 10, for example by means of a plug contact.
  • suitable lateral guide devices 11, 25 are preferably used in the system 1 of the machine.
  • the use of scroll rails 11 is recommended for thin panels 7 or scroll panels 7.
  • the alignment process then takes place on the system 1 of the machine, taking into account the measured values of the specifically selected sensor 24.1, 24.2, 24.3, in particular at full machine speed. If the sensors 24.1, 24.2, 24.3 are in a suitable position, the evaluation of the measured values of a plurality of sensors 24.1, 24.2, 24.3 can also be considered. In the case of new or different tabular substrates, in particular scroll panels 7, the system 1 can be readjusted according to the steps described.
