Abstract
A system for curing a binders applied to glass fibers is disclosed. The curing of the binder is accomplished by passing the binder coated glass fibers through a curing oven having one or more temperature zones. The temperature of the binder coated glass fibers is monitored and the temperature in the curing oven is adjusted to ensure proper heating of the glass fibers thereby ensuring uniform curing of the binder composition. Temperature measurements are made either as the product traverses the oven or as the cured product exits the curing oven. The invention is particularly useful for curing acrylic thermoset binders and formaldehyde-free binders.
