Abstract

A method of manufacturing ligno-cellulosic fiberboard according to the so-called semi-wet method, in which the material is softened and disintegrated to form a wet pulp that is suspended in a gas, from which it settles to form a pulp sheet, characterized in that the humidity ratio of the wet pulp is compensated before the pulp sheet is formed and that the compensation of the humidity ratio is achieved by removing liquid from the pulp by mechanical pressing operations.
