A method for the continuous production of boards of a ligno-cellulosic fiber material wherein the material is broken up into particles and/or fibers. These are dried, glued and formed to a mat. The mat is compressed to a finished board while steam is introduced. According to the present invention, the compression is performed as a single step and the steam is introduced through one or many compression rollers. By injecting steam in this way a sufficient cure is obtained to withstand the spring back characteristics inherent of the fibers so that it is possible to obtain a finished thickness of the board with one single compression step.
L'invention concerne un procédé de fabrication en continu de planches composées de fibres de lignocellulose, dans lequel la matièrre est décomposée en particules et/ou fibres. Celles-ci sont séchées, collées et mises sous forme de mat. Ledit mat est comprimé pour former une planche finie, tandis que de la vapeur y est introduite. Selon la présente invention, la compression se fait en une seule étape et la vapeur est introduite par un ou plusieurs cylindres presseurs. Une telle injection de la vapeur permet un durcissement suffisant pour que les caractéristiques de détente propres aux fibres soient respectées, grâce à quoi on obtient en une seule étape de compression une épaisseur de planche finie.
