A method for assessing the cure status of a fibrous blanket manufactured with mineral fibers and binder is disclosed and comprises a using an online optical reflectance measurement as an assessment of cure status. The optical reflectance measurement may preferably be a color image taken of any surface, and in particular of a sectioned face, after which the image is optionally divided into multiple regions of interest (ROI) and analyzed for a color system variable that is representative of cure status. In some embodiments, the color system variable is the B value. Alternatively, the optical reflectance measurement may be UV or IR reflectance of a sectioned face. When two or more regions of interest are defined on a sectioned face, comparative information is valuable to assess cure at different levels, layers or portions of the interior of the fibrous product.

Method for online determination of cure status of glass fiber products

A method and apparatus for assessing the cure status of a fibrous blanket manufactured with mineral fibers and binder is disclosed and comprises using continuous thermal measurement as an assessment of cure status. A plurality of thermocouples are installed in various oven locations both above and below the path of the fibrous pack to be cured and readings from the thermocouples are compared by a processor. The thermal measurements may be inlet or outlet temperatures of any particular zone or series of zones; or entry or egress temperatures; or averages or differences of measurements from selected thermocouple locations.
