摘要:
The subject of this invention is a method of making a curved glass pane of laminated glass, such as an automobile windshield, in which one of the two single glass sheets is provided, on the surface bearing against an intermediate layer, with a film of a baking finish. The baking finish is applied onto the inner face of the single glass sheet intended for the outside. The glass sheet, provided with the dried baking finish (i.e., a colored film), is laid, with the film upwards, onto the single glass sheet intended for the inside. The pair of glass sheets, in this arrangement, is prebent on a bending frame with simultaneous baking-in of the colored film. Subsequently, the two glass sheets are transposed and, in this transposed arrangement with the colored film on the inside, are finally bent in a second bending operation on a bending frame corresponding to the final shape of the outer sheet.
