Abstract

See full text

A fiberglass product usable as an end product or an intermediate product is formed as a pack in a forming station but only 1/7th of the conventional quantity of binder is applied. After curing to a self-sustaining form, additional binder is added in an amount in excess of the amount required in the final product and then the excess binder and moisture is removed by one or more stripping steps. Additional moisture is removed by electronic means to the desired moisture level for commercial products.
