  • the camera 75 is thus an example of a detection device 69 that is able to simultaneously position several material webs 65 in the storage device 60.
  • the loop section over the substantial part of its length, with the exception of the free Loop section, securely guided and held so that especially touching the loop legs, for example due to electrostatic attraction, reliable is avoided.
  • the non-guided, free loop section on the other hand stands calmly and flutter-free between the Suction belts and can be used as a well-detectable reference surface for the distance measurement using the one aimed at him Serve sensor device.
  • the positionally reliable web guide can be guaranteed without special sealing measures, such as they are required for vacuum accumulators.
  • a change to film webs of other widths without Effort possible because there are no side walls to limit the path must be provided.
  • the storage dimension can be reduced by the degree of filling and / or the filling or Emptying speed of a memory using the Sensor device 50 monitors and, for example, the rolling speed the unwind storage roll 15 depending is controlled by filling level and / or filling speed.
  • On Distance sensor is particularly advantageous for this, because not only the absolute levels, given by the (vertical) Position of the free loop section, detected can be, but by observing the temporal Course of the distance in particular also filling and emptying speeds.
