  • high feed rates with which the blank is moved through the wood-based panel pressing device are more likely to cause material defects. So the blank must be compressed during pressing. But this requires that air is pressed out of the blank. If this happens too quickly, the escaping air can cause fibers of the fiber cake to break, resulting in crater-like eruptions.
  • Such outbreaks which are also called Ausbläser, usually lead to the produced wood-based panel can not be used in the area of the outbreak, so that committee arises.

  • the measurement data of the pixels does not change over time.
  • the measured data fluctuate, for example due to statistical measurement errors or randomly changing environmental conditions. If a disturbance occurs, for example an outbreak of a gas bubble described above, the property changes more in time.

Thereafter, the feed rate and / or the inlet angle ⁇ is increased until it comes to the above-described outbreaks or blowers, which lead to rejects. At the same time, the change parameter is determined. The tolerance value is chosen to be below the change value at which reject occurs.
  • the evaluation area pixels are grouped in at least 20 areas. It is beneficial if these areas adjoin one another. This means that there are no pixels or so few pixels between two areas that blowouts can still be reliably detected.
