Abstract

The present disclosure includes systems and methods for manufacturing a composite wood product. In some embodiments, the method includes the steps of forming a mat from a plurality of wood elements and an adhesive, the mat having a width W measured substantially perpendicular to a longitudinal axis of the mat and an initial thickness T 1 . The mat is then moved in a machine direction, the machine direction being substantially parallel to the longitudinal axis and the temperature across the width W of the mat is adjusted. The mat is then compressed into a billet having a final thickness T 2 . In some embodiments, the system includes a continuous movement mechanism, a side preheat assembly, and a press assembly.

First claim

I claim:

1. A system for manufacturing a composite wood product, the system comprising:
a mat composed of a plurality of wood elements and an adhesive, the mat comprising:
a width W measured substantially perpendicular to a longitudinal axis of the mat and an initial thickness T 1 ;
a top face extending along the longitudinal axis;
a bottom face that is substantially parallel to the top face;
a first side face that is substantially perpendicular to the top face;
a second…
