Claim 56:
57. A method of manufacturing a composite wood product, comprising:
applying a filler material to a plurality of wood elements;
applying a compression force to the plurality of wood elements, the compression force applied by a roller element that includes a surface that applies the compression force to the plurality of wood elements; and
bonding the plurality of wood elements into a composite wood product, the bonding comprising delivering ultrasound energy to the plurality of wood elements, wherein the ultrasound energy has a frequency within a frequency range of 10 kHz-20 MHz, and wherein the ultrasound energy is delivered by an ultrasound transducer via the roller element;
wherein the ultrasound energy comprises a first amount of ultrasound energy and a second amount of ultrasound energy, wherein the first amount of ultrasound energy is delivered to a first depth of the plurality of wood elements, wherein the second amount of ultrasound energy is delivered to a second depth of the plurality of wood elements, wherein the second depth is different from the first depth, and wherein the second amount of ultrasound energy is different from the first amount of ultrasound energy.
