  • Patent number: 12208605
    Abstract: A method for making a laminated glazing panel is described. A bolt having a head portion and a stem portion extending therefrom is positioned in a hole in a sheet of glazing material so that a first surface of the head portion is faces in the direction of a first major surface of the sheet of glazing material and the stem portion extends beyond a second major surface of the sheet of glazing material. A sheet of adhesive interlayer material is positioned on the first major surface of the sheet of glazing material to cover the first surface of the head portion. Suitable lamination conditions are used to laminate the sheet of adhesive interlayer material to the sheet of glazing material. During lamination, fluid trapped between the first surface of the head portion and the sheet of adhesive interlayer material is removed via a fluid pathway associated with the stem portion. Laminated glazing panels made using the method are also described.

  • Publication number: 20250001736
    Abstract: The present invention concerns a glazing for electric heating, comprising a first glass sheet, a first masking layer around the periphery of the first glass sheet, an aperture in the first masking layer for a sensor, a second glass sheet bonded to the first glass sheet by a ply of interlayer material, a carrier film positioned between the ply of interlayer material and the first glass sheet, an electric heating element on the carrier film, and a second masking layer on the carrier film. The second masking layer positioned on a carrier film causes less stress in the glass sheets during moulding and thus less optical distortion. The invention also concerns a method of manufacturing the glazing and use of the glazing for example as a window for a vehicle.
