The present invention provides an apparatus and method 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.

Méthode et dispositif servant à remplir et sceller une ouverture pratiquée dans un laminé et en particulier, sceller une encoche découpée dans le pare-brise d'un véhicule. Le cadre de moulage comprend un moule, une plaque de fixation, un orifice d'entrée du produit de scellement et un trou d'aération. Les surfaces du moule, qui entrent en contact avec le matériau de scellement résilient, sont lisses et servent à former la surface du produit de scellement utilisé pour remplir la cavité. Le cadre de moulage est fixé au laminé de sorte que des parties déterminées du moule chevauchent des parties déterminées du laminé immédiatement près de l'ouverture. Le produit de scellement est injecté dans l'ouverture formée par le laminé et le cadre de moulage afin de sceller la cavité. Le produit séche jusqu'à ce qu'il atteigne la dureté voulue puis on enlève le cadre de moulage du laminé.
