Optical sensors in side trimming systems of saw mills

The tree trunk cut into planks in saw mills still shows the wane of the original tree on the edges. In order to achieve an optimum cutting width and thus a maximum yield here, laser triangulation sensors are installed every 30 to 50 cm which measure the transverse section of the plank in the flow path. The maximum width of the plank is calculated using special software.
