  • Patent number: 4329194
    Abstract: A method of constructing a fiberglass structure features that enable a gelcoat protective layer to be applied to an article formed in an automatic process. In the process, a web of fiberglass is drawn through a bath of structural resin to impregnate the fiberglass with the structural resin. A web of organic, porous veil material is drawn through a bath of gelcoat resin simultaneously with the structural resin impregnated web of fiberglass. The two webs are squeezed together, and the resin metered to provide a composite web having a layer of resin and a layer of gelcoat. A mold draws the composite web off of the rollers. Once a section has been drawn onto the mold, the web is sheared. Then the mold is moved into an oven for heating and curing the article.
