Abstract

Method of shaping, preferably bending, hardened, flat wood fiber boards comprising cellulose fibers, lignin and hardening oil by moistening, heating, bending and subsequent cooling. Moistening is carried out with a chemical solution which temporarily dissolves the lignin, facilitates the penetration of liquid and releases the fibre bonds, whereafter the boards are heated to about 80-120 DEG C, subsequent to which they are bent or moulded to the desired, predetermined shape.
