ABSTRACT:
The invention relates to a method and device with which it is possible to arrange complicated shapes with considerable differences in height in wood fiber board, and in particular but not exclusively so called MDF (Medium Density Fiberboard). The deformation of the wood fiber board which can be achieved with the invention is known in the art as extusion, wherein a considerable plastic deformation takes place accompanied by flow and stretch of the material.
