Method and apparatus for dielectric projection bonding of wood materials

Claim 1

A METHOD OF UNITING PIECES OF DIELECTRIC MATERIAL FOR THE PRODUCTION OF AN ELONGATED COMPOSITE BODY INCLUDING THE STEPS OF: ASSEMBLING THE PIECES IN POSITIONS RELATIVE TO EACH OTHER TO FORM AN ELONGATED ASSEMBLY OF THE DESIRED BODY CONFIGURATION; APPLYING HEAT-RESPONSIVE GLUE TO THE ADJOINING SURFACE IN THE ASSEMBLY; PLACING THE ASSEMBLY UNDER PRESSURE ACROSS THE PLANES OF SAID SURFACES; AND WHILE UNDER SUCH PRESSURE PASSING THE ASSEMBLY LONGITUDINALLY THROUGH A HIGH FREQUENCY CAVITYGENERATED ELECTRIC FIELD AT A SPEED ADJUSTED TO HEAT THE OPPOSITE MARGINAL PORTIONS OF SAID GLUE SURFACES WITHOUT CURING THE INTEMEDIATE PORTIONS OF THE GLUE SURFACES IN THE TIME INTERVAL THE ASSEMBLY IS EXPOSED TO THE ENERGY GENERATED BY THE RESONATOR, WHEREBY THE, ASSEMBLY MAY BE RELEASED FROM PRESSURE TO BE HELD TOGETHER BY SAID MARGINAL PORTIONS FOR SUBSEQUENT LOW TEMPERATURE CURING OF SAID INTERMEDIATE PORTIONS.
