CONSTITUTION: A hollow part is shaped in wood of large sized cross sections. The wood with the hollow part is dried based on heating. A moisture escaping preventive unit is arranged on the external surface of the wood. The moisture escaping preventive unit is arranged on the surface or the transversal cross section of the wood.
