Abstract:
1. A method for manufacturing a composite wood product comprising the steps of: forming a mat from a plurality of wood elements and an adhesive, the mat having first and second side faces extending along the longitudinal axis of the mat, the mat being divided into three or more sections defined by two or more boundary planes, the two or more boundary planes being substantially perpendicular to the first and second side faces of the mat; moving the mat in a machine direction, the machine direction being substantially parallel to the longitudinal axis; positioning a first side energy generator assembly along the first side of the mat at the first boundary plane and a second side energy generator assembly along the first side of the mat at the second boundary plane, and positioning a third side energy generator assembly along the second side of the mat at the first boundary plane and a fourth side energy generator assembly along the second side of the mat at the second boundary plane; applying energy to the mat with the first, second, third, and fourth side energy generator assemblies in first, second, third, and fourth horizontal directions, each of the first, second, third, and fourth horizontal directions being substantially perpendicular to the machine direction; compressing the mat to form a billet; and cutting the billet along first and second cutting planes that substantially correspond to the first and second boundary planes to form first, second, and third beams.
