  • Publication number: 20240042739
    Abstract: A method for producing laminated glass for automobile windows includes: heating and bend forming two glass plates; and bonding together the two bend-formed glass plates via an interlayer film, wherein before the heating and bend forming of the two glass plates, at least one glass plate of the two glass plates that are flat, is conveyed by a conveying unit while either a conveying unit-facing surface of the at least one glass plate or a non-facing surface of the at least one glass plate that is opposite to the conveying unit-facing surface is scratched by the conveying unit, and in the bonding together of the two bend-formed glass plates via the interlayer film, the scratched surface is disposed such that the scratched surface is situated on a vehicle-interior side upon the laminated glass for automobile windows being attached to an automobile.
