Rather, as an end product, several (endless) wood-based panels run out of the press, which are arranged essentially separated from one another by the separating layer and can be separated from one another after the pressing process and consequently separated. The separation or separation can take place immediately after pressing or only after appropriate further processing or transport and / or storage.
