Abstract

A method for making laminated glass. The sheet includes two glass substrates with an interlayer sheet between them. This sheet includes a polymer based film provided on one of the surfaces with a thin functional layer. The sheet is cut out in dimensions substantially identical to or greater than one of the glass substrates. The sheet is slit on at least the thickness of the film provided with the functional layer so as to delimit at least a peripheral zone of the film located between the slitting line and its edge. The interlayer sheet is assembled between the glass substrates. The peripheral zone is then detached by mechanical traction to transform the laminated glass sheet.
