Abstract:
1. Process for utilizing electromagnetic-radiation spectroscopic instrumentation for quantitative measurement of resin-loading of wood-materials during on-line assembly prior to bonding into composite wood-product, comprising (A) providing spectroacopic instrumentation including (B) establishing that a pre-determined linear relationship exists between quantitative resin-loaded percentage weight of said wood materials and absorption of radiation in said wavelength range; (C) calibrating said spectroscopic instrumentation for non-invasive quantitative measurement of resin-loading of said wood materials while moving in an assembly line, by (D) establishing resin-content of said test-samples so as to present incrementally-progressive resin-loading of wood-materials for respective test-samples, with said resin-loading being selected from the group, consisting of (E) establishing relative movement between said test-samples and said irradiation source and sensor means instrumentation by selecting a rotatable conveyance surface capable of being driven at a controlled rotational rate, so as to (F) selecting a wavelength range from the group consisting of wherein said spectroscopic instrumentation includes a full visible-light spectrum lamp for illuminating said test-samples, from which the red portion of said visible light is absorbed by resin-content of said wood-materials.
