A method for bending integral wood, in which method the wood blanks (5) are heated and compressed in the direction of the longitudinal axis of the grain or fibers, whereby the wood blank (5) becomes more pliable to bend, the wood blank is bent to a desired shape and the wood blank is finally dried. The heating step and the compression step of the wood blanks (5) in the direction of the grain of fibers (plasticization) are performed synchronously so that an electric field is generated and aimed through the wood blanks (5) and the wood blanks are compressed in the direction of the grain or fibers, and the bending step and the drying step are performed synchronously so that the wood blank (5) bent to the desired shape is heated by means of an electric field in a bending unit to a temperature in the range 230 - 250 DEG C, whereby the shape of the bent wood blank remains essentially irreversibly permanent. The invention also concerns an apparatus suited to implement the method. |
