Abstract
The process relates to the production of boards of wood-based material, in particular, oriented strand board, chipboard or fiberboard comprising lignocellulose- and/or cellulose-containing particles. The particles, in the form of chips, fibers, chippings or the like, are mixed with a binder and scattered in a scattering station onto a moving molding belt to form a mat of pressed stock. The mat of pressed stock is pressed and cured by the application of pressure and heat in a platen press or a continuously operating press. To accomplish surface structuring during the production cycle, the finished board of wood-based material just released from the pressing operation is subjected to a structuring operation on one or both sides.
