Abstract
The present invention is a method of forming and heating a compressed composite wood product. The method includes introducing a mat assembly of resinated discrete wood elements into an oscillating compression press. Once the material is within the oscillating compression press, the compression/release oscillation is controlled to form the material. Specifically, the compression/release oscillation is controlled to heat the mat assembly to a to at least a cure temperature of the resin.
Claims15
A method of forming a compressed composite wood product, comprising:
- introducing a mat assembly of resinated discrete wood elements into an oscillating compression press;
- and
- controlling oscillation compression of the press such that cycling between a compression phase and a release phase serves to heat the mat assembly to at least a cure temperature of the resin.
A method of forming a compressed composite wood product, comprising:
- introducing a mat assembly of resinated discrete wood elements into a press having one or more platens on opposing sides of the mat asssembly;
- and
- moving the platens in a substantially circular motion such that cycling between compressing the mat assembly and releasing the mat assembly serves to heat the mat assembly to at least a cure temperature of the resin.
