Abstract

Apparatus for impregnating wood veneer with a liquid impregnant comprises a container having an upper chamber communicated to a lower impregnation chamber. A clamping mechanism is releasably engageable to a peripheral region of the wood veneer and is cooperably received in the upper chamber in a manner to suspend the wood veneer in the impregnation chamber. An elevator overlies the container and is releasably connectable to the clamping mechanism for lowering the clamping mechanism into the upper chamber to suspend the wood veneer in the impregnation chamber therebelow. The clamping mechanism is disconnected from the elevator such that the clamping mechanism remains in the upper chamber during impregnation of the wood veneer with liquid impregnant. The impregnation chamber is evacuated by a vacuum pump after the wood veneer is suspended therein, and liquid impregnant is introduced from a storage tank to the impregnation chamber about the wood veneer. A venting valve is openable to establish ambient pressure in the impregnation chamber to impregnate the wood veneer with the liquid impregnant therein. Following impregnation, the clamping mechanism is reconnected to the elevator to enable removal of the impregnated wood veneer from the container.
