Abstract: Embodiments of the present disclosure describe ambient temperature pressing (“cold pressing”) of a wood-based product using protein/PAE adhesives within industrially suitable set times and press pressures. A method includes preparing an adhesive comprising a protein source and polyamideamine-epichlorohydrin (PAE) resin, applying the adhesive to one or more wood-based components, and cold pressing the one or more wood-based components to form a wood-based structure, the cold pressing being the only pressing operation in the formation of the wood-based structure after applying the adhesive to the one or more wood-based components. Other embodiments may be described and/or claimed.

Abstract: A scanning system which scans for defects in decorative panels by generating images of the panels. A comparative program, i.e., recipes of samples of decorative panels having defect types and degrees, enables the system to make comparisons of defects and through said comparisons to grade the defects whereby the panels are graded as, e.g., acceptable, re-work, shop or reject. The program is modified for different decorative wood species and a controller dictates the comparative program to be applied for different customer orders of decorative wood panels.

Abstract: A system for producing blanks for finish plywood which includes development of a recipe of selected veneer sheets, automatically and rapidly, e.g., via linear actuator, arranging the selected veneer sheets for sequential stacking and bonding of the sheets to produce a rough blank having a determined thickness that enables minimal and sufficient abrasive planing.
