Abstract
A process and installation for the continuous production of boards of wood-based material, includes the steps of forming on a continuously moving scattering belt, a pressed material mat includes an initial mixture of chips and/or fibers from a scattering station and mixed with binder; precompacting and preheating the pressed material mat between the scattering station and a main pressing region; and bringing into an end form and curing the pressed material with the application of pressure and heat in a main pressing regions. The moisture level of the pressed material mat is less on entry into the main pressing region than the moisture level of the initial mixture in the scattering of the pressed material mat, part of the moisture imparted to it in the scattering being extracted again by hot-air preheating.
