Verfahren zur Herstellung von Holzspanplatten und mitteldichten Holzfaserplatten

A process is described for the manufacture of particle boards and medium-density wood building boards. In the process, wood chips or wood fibre impregnated with a binding agent are made into particle or fibre mats and are then pressed into boards at high temperature. The process is characterized by the fact that, during the forming process, at least one surface of the particle or fibre mat is provided with a layer consisting of wood chips or wood fibres containing a binding agent which is not thermally curable, and the particle or fibre mats formed in this way are then pressed.
