METHOD OF CONTINUOUS MANUFACTURE OF BOARD OF LIGNOCELLULOSIC FIBER MATERIAL

摘要

A method of continuous manufacture of board of lignocellulosic fiber material where the material is disintegrated to particles and/or fibers, dried, glued and formed to a mat and pressed to a finished board. In a first step the formed mat is heated through by steam and compressed to an at least partially hardened board with substantially uniform density. In a second step the surface layers of the board are compressed to higher density and hardened in a calibration zone to a finished board.
