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.
Claims38
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 that includes a first 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;
- wherein the ultrasound energy is delivered by an ultrasound transducer that is integral with the press, and wherein the ultrasound transducer is arranged to be flush with the first surface of the press.
