Abstract
The present method includes an apparatus for filling and sealing an opening in a laminate and in particular sealing the cut-out notch area of a vehicle windshield. A mold fixture includes a mold, a backing plate, a sealant inlet and a vent. The mold has resilient sealant contacting surfaces that provide a smooth surface for forming the surface of the sealant filling the opening. The mold fixture is clamped to the laminate such that selected portions of the mold overlay the opening and remaining portions of the mold overlay selected portions of the laminate immediately adjacent the opening. Sealant is injected into a cavity formed by the laminate and the mold fixture to seal the opening. The sealant is allowed to cure to achieve a desired hardness and the mold fixture is then removed from the laminate.
