Patent number: 12208605Abstract: 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.Type: GrantFiled: January 27, 2021Date of Patent: January 28, 2025Assignee: Pilkington Group LimitedInventor: Michael John Davidson
