Title:
A METHOD AND APPARATUS FOR INCREASING THE HARDNESS INTENSITY OF WOOD
Document Type and Number:
WIPO Patent Application WO2000013865
Kind Code:
A3
Abstract:
A device for increasing the hardness and intensity of wood which comprises chuck means for holding the wood in a fixed position for processing, a compression-shaped forming die for compressing the wood being processed, an ultrasonic wave-generating device operatively connected with the compression-shaped forming die for applying sound waves to the wood, a forming mold positioned downstream of said compression-shaped forming die for receiving wood therefrom, said forming mold further compressing said wood to remove a portion of the water contained therein, and means for advancing the chuck means containing the wood being processed through the compression-shaped forming die, the ultrasonic wave-generating device and the forming mold.
