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 at a location remote from the forming station 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 vacuum stripping steps.

L'invention porte sur un produit de fibre de verre pouvant être utilisé comme produit fini ou semi-ouvré. Le produit de fibre de verre est formé en paquet dans une station de formage, mais seulement 1/7 de la quantité classique de liant est appliquée. Après le séchage pour produire une forme autoportante, un volume de liant additionnel et supérieur au volume requis dans un produit fini de liant est ajouté à un poste éloigné de la station de formage; le liant excédentaire et l'humidité présents dans le produit sont éliminés au cours d'une ou de plusieurs étapes d'extraction sous vide.
