Abstract
A method of manufacturing plates, such as chipboards, fibre boards and the like boards, where the raw material in form of biomass particles, such as wood chips, wood fibres and the like applied with a thermosetting binder is spread onto a preforming band into an endless mat, and where this mat (B) is pre-compressed in a continuously operating prepress (C) and then completely pressed in a continuously operating hot press, whereby the mat (B) is compressed into the desired thickness of the finished plate and the thermosetting binder is hardened. According to the invention, the mat (B) is pretreated by means of steam immediately before the introduction into the hot press (E) by means of a device (F) so as to obtain predetermined gradients of moisture content and temperature across the thickness of the mat. As a result the capacity of the apparatus can be increased at the same time as the energy consumption can be reduced. Furthermore, the dimensions and hydraulics of the press (E) can be reduced to a predetermined capacity. Finally, the possibility of controlling the total processing is improved concerning achievement of predetermined qualities of the finished plate characterized by the density profile of said plate across the thickness of said plate.
