Abstract

A process for the manufacture of wood chip boards and medium density wood fibre boards is described, in which the wood chips or wood fibres provided with binder are formed into chip or fibre mats and subsequently pressed at elevated temperature to form boards. The process is distinguished in that during the forming process at least one surface of the chip or fibre mat is provided with a layer of wood chips or wood fibres containing thermally non-curing binder and the chip or fibre mats thus formed are subsequently pressed.
