Abstract
The hardness of the outer layer of chipboard with fibre top layer as described in the parent Specification is varied by varying the amount of water in the fibre layer before the single pressing operation. Less than 30% water gives a soft outer layer while for very hard outer layers, a water content of up to 80% may be used. Further hardening may be made by treating the outer layer with glue or oil.
