Abstract
A filler material is applied to a plurality of wood elements. The plurality of wood elements is bonded into a composite wood product, where the bonding includes delivering ultrasound energy to the plurality of wood elements. The ultrasound energy has a frequency within a frequency range of 10 kHz-20 MHz.
Claims52
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 press, wherein the press includes a first surface that applies a first compression force to the plurality of wood elements and a second surface that applies a second 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;
- wherein the ultrasound energy is delivered by a first ultrasound transducer that is integral with the press, and wherein the first ultrasound transducer is arranged to be flush with the first surface of the press.
