Method for making a laminated glass sheet
First Claim
1. A process for manufacture of a laminated glazing unit comprising at least two glass substrates assembled by an intermediate film having at least one ply based on a polymer or polymers provided on at least one of its faces with a functional thin layer or a stack of functional thin layers having properties of reflection in infrared, wherein the process includes the following steps:
- a)—
the intermediate film already containing at least the ply provided with the thin layer or the stack of thin layers is cut to dimensions larger than at least one of the two glass substrates, b)—
the intermediate film is incised through at least a thickness of the ply provided with the thin layer or the stack of thin layers having properties of reflection in infrared, in such a way as to define at least one peripheral zone or zones of said ply localized between an incision line and an edge of the ply, c)—
the intermediate film is assembled between the two glass substrates by adjoining thereto any polymer ply or plies thereof which was or were missing, d)—
the peripheral zone or zones of the ply is or are detached by pulling it on them mechanically, e)—
the laminated glazing unit is transformed, the steps taking place in the above order.

Abstract
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.
