  • the invention relates in particular to continuously operating wood-based panel pressing devices, in which the fiber cake is continuously scattered and pressed and / or pressed. It is desirable to operate such a wood-based panel pressing device at the highest possible speed.
  • high feed rates with which the fiber cake is moved through the wood-based panel pressing device, are more likely to cause material defects. So the fiber cake must be compressed during pressing. But this requires that air from the fiber cake is pressed out. 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.
  • Another source of error is a fluctuation in the fiber cake beyond a given degree of tolerance.
  • the invention has for its object to reduce waste.
  • the invention solves the problem by a generic Holzwerkstoffplatten- pressing device, wherein the control device comprises a camera and an evaluation unit, and wherein the camera arranged at an inlet region of the wood material board pressing device and the evaluation unit is designed for automatically performing a method with the steps (i) continuously recording images of the lead-in area, (ii) continuously acquiring measurement data for evaluation area pixels of images that belong to a given evaluation area that includes at least one area that is oriented upwards to a desired horizon of the Fiber cake adjacent so that evaluation data is obtained; and (iii) outputting a signal when the evaluation data changes by more than a predetermined tolerance value.

It is another advantage that this monitoring is possible with very little effort.
  • the necessary components such as the camera and the evaluation unit in the form of evaluation electronics are standard products that can be easily procured. The fact that the process monitoring by means of camera works at all, had been classified as not realistic, since such wood-based panel pressing devices can dust heavily.
