Definitions

• the invention relates to a method and to a device for manufacturing a panel of laminated glass as well as to the product made by the method.
• Laminated glass is a type of safety glass that holds together when shuttered. In the event of breaking, it is held in place by a plastics interlayer, typically of Polyvinylbutyral (PVB), between its two or more layers of glass.
• PVB Polyvinylbutyral
• the plastics interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from break- ing-up into large sharp pieces.
• laminated glass panels with integrated electronic components such as light emitting diodes (LED) are often used, e. g. for displaying information or lighting purposes.
• the manufacturing of a laminated glass panel with electronic components typically comprises the steps of depositing a conducting layer on a first layer of glass, realization of electronic circuits in the conducting layer and depositing of electronic components on the conducting layer, connected to the electronic circuits.
• the plastics interlayer is then deposited
• the sandwich is obtained by the application of a second layer of glass on the plastics interlayer, which is then laminated as outlined before.
• An advantage of the present invention is the possibility for depositing a plastics interlayer on a glass layer that is not exposed to a risk of pulling-out electronic components.
• a method for manufacturing a panel of laminated glass with the steps of providing a first glass plate, providing a plastics interlayer, cutting the plas- tics interlayer to a tailored sheet with dimensions which relate to the dimensions of the first glass plate, applying the tailored sheet of plastics interlayer on the first glass plate, applying a second glass plate on the tailored sheet of plastics interlayer, and laminating the first glass plate, the tailored sheet of plastics interlayer and the second glass plate.
