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 T1. 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 T2. In some embodiments, the system includes a continuous movement mechanism, a side preheat assembly, and a press assembly.
Claims6
A system for manufacturing a composite wood product from a mat composed of 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 T1, the system comprising:
- a continuous movement mechanism configured to move the mat in a machine direction, the machine direction being substantially parallel to the longitudinal axis;
- a side preheat assembly comprising one or more side energy generator assemblies configured to apply energy to one or more sides of the mat, the energy being applied in one or more horizontal directions, the one or more horizontal directions being substantially perpendicular to the longitudinal axis of the mat;
- and
- a press assembly configured to compress the mat to a billet having a final thickness T2.
