Patent ID: 6886618

Claim:
A system for feedback adjusted in-line addition of a curing accelerator/catalyst to a thermosetting resin adhesive used to adhesively bond furnish material in a wood substrate to form a wood-based composite, comprising: a first computer electrically coupled to an applicator, a thermosetting resin pump, a first flow meter and a conveyor; and a second computer electrically coupled to the thermosetting resin pump, the first flow meter, the applicator, a temperature sensor, a moisture sensor, a flush port control, a curing accelerator/catalyst pump, and a second flow meter wherein: the first computer is configured for adjusting a speed of the conveyor in accordance with a predetermined adhesive application scheme, the conveyor conveys the wood substrate, the first flow meter indicates a flow rate of resin from the thermosetting resin pump, the applicator applies a resin and curing accelerator/catalyst mixture to the wood substrate, the temperature sensor determines a temperature of furnish material in a wood source supplying furnish material for the wood substrate, the moisture sensor determines a moisture of furnish material in the wood source, the flush port control initiates flushing of an in-line mixer, the second flow meter indicates a flow rate of the curing accelerator/catalyst from the curing accelerator/catalyst pump to one of a conduit to the applicator and the in-line mixer, and the second computer determines and controls curing accelerant/catalyst flows according to a predetermined temperature-moisture scheme by monitoring temperature and moisture of the furnish material in the wood source and inputting measurements of the temperature and moisture to the predetermined temperature-moisture scheme for adjusting curing accelerant/catalyst input.
