ABSTRACT:
A wood material, into which a synthetic resin solution or the like is injected, is held from its surface and back by heating plates in a closed container. The inside of the heating plate is provided with a heating medium passageway through which a heating medium can flow. A heating medium tank is connected to the heating medium passageway through a heating medium feeding passageway and a circulating pump. Warm water or steam are fed to the heating medium passageway. The warm water or steam have the temperature which can volatilize a medium from the heating medium tank or can volatilize the injected solution. A vacuum pump is connected to the closed container. The pressure is reduced in the closed container correspondingly to the operation of the vacuum pump.
