in a method for making laminated glass , a 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 .
