Abstract
The disclosure relates to a wood material panel pressing device for pressing a fibrous press cake in order to produce a wood material panel, including an inspection device that is designed to emit a signal in the event of a disruption. According to the disclosure, the inspection device has a camera and an evaluation unit, the camera is arranged in an intake region of the wood material panel pressing device and the evaluation unit is designed to automatically carry out a method featuring the steps: (i) continuous recording of images (B) of the intake region, (ii) continuous detection of measurement data for evaluation region pixels of images (B), which belong to a predefined evaluation region comprising at least one region bordering a target horizontal of the fibrous press cake at the top, such that evaluation data is obtained, and (iii) emission of a signal if the evaluation data changes by more than a predefined tolerance value (DT).
