Process and apparatus for non-invasive measuring of binder mix loading of glass fibers for monitoring production of construction insulation product, such as roofing and wall insulation. Visible (VIS) and near infrared (NIR) spectroscopy is used on a static or moving support substrate, and is advantageous when utilized in an on-line production processing following binder mix loading of fibers and prior to curing treatment of binder mix and fibers. The blend is then conveyed to and through curing treatment to form insulation product, then exposed to VIS-NIR radiant energy and a sensor collects resulting data for absorption following penetration of the VIS-NIR radiant energy. The spectrophotometer is calibrated to facilitate accuracy; and, can be used to verify loading following during. The amount of binder mix, in the binder mix/fiber blend, is adjusted if the blend is outside of desired loading specifications. |
