Abstract
The present invention provides a process and system for the manufacture of wood-based composites that implement feedback adjusted in-line addition of a curing accelerator/catalyst to a thermosetting resin adhesive based on at least one of: present moisture content of the wood substrate being bonded and the temperature of the wood substrate being bonded. The method includes: measuring the flow rate of a flowing stream of resin adhesive; measuring the flow rate of a flowing stream of accelerator/catalyst; mixing the flowing stream of accelerator/catalyst and the flowing stream of resin adhesive to form a mixed catalyzed resin adhesive in a proportion of resin adhesive and accelerator/catalyst determined by said flow rates; applying the mixed catalyzed resin adhesive to the wood substrate in an application area; measuring a present moisture content and a present temperature of the wood substrate prior to applying the mixed catalyzed resin adhesive thereto; varying on a continuous basis, the proportion of the accelerator/catalyst and resin adhesive in the mixed catalyzed resin adhesive in accordance with at least one of the present moisture content and the present temperature and bondi…
