Abstract
An automobile pane of laminated glass with a plurality of mutually parallel antenna wires having a diameter of 15 to 50 microns, which are virtually invisible to the eye. For producing such an antenna pane, the antenna wires are laid and fixed on a temporary support sheet, provided with an adhesive coating of the same thermoplastics polymer as the intermediate film of the laminated glass pane. By means of the temporary support sheet, the wires are transferred onto one of the two glass sheets forming the laminated glass pane. After removal of the temporary support sheet, the two glass sheets and the thermoplastics sheet forming the intermediate film are further processed in the usual manner to form the laminated glass pane
Claims12
A method for manufacturing a laminated glass pane having at least one antenna wire disposed in an intermediate thermoplastic film, comprising the steps of:
- forming a temporary support sheet;
- providing an adhesive coating on a major surface of said temporary support sheet;
- directly connecting said at least one antenna wire to a terminal lug;
- placing said at least one antenna wire and said directly connected terminal lug in a desired geometrical arrangement on said adhesive coating provided on said temporary support sheet;
- fixing said at least one antenna wire and said terminal lug to said adhesive coating by the application of heat and pressure to form an antenna component having a single support sheet on one side of said antenna wire with an opposite side of said antenna wire being uncovered;
- fixing said opposite side of said antenna wire of said antenna component to a first glass sheet;
- removing said temporary support sheet from said adhesive coating, thereby leaving said adhesive coating and said at least one antenna wire fixed to said first glass sheet;
- and
- fixing a second glass sheet to said adhesive coating opposite to said first glass sheet.
A method for manufacturing a laminated glass pane having at least one metal wire disposed in an intermediate thermoplastic film, comprising the steps of:
- forming a temporary support sheet;
- providing an adhesive coating on a major surface of said temporary support sheet;
- directly connecting said at least one metal wire to a terminal lug;
- placing said at least one metal wire and said directly connected terminal lug in a desired geometrical arrangement on said adhesive coating provided on said temporary support sheet;
- fixing said at least one metal wire and said terminal lug to said adhesive coating by the application of heat and pressure to form an wire assembly having a single support sheet on one side of said metal wire with an opposite side of said metal wire being uncovered;
- fixing said opposite side of said metal wire of said wire assembly to a first glass sheet;
- removing said temporary support sheet from said adhesive coating, thereby leaving said adhesive coating and said at least one metal wire fixed to said first glass sheet;
- and
- fixing a second glass sheet to said adhesive coating opposite to said first glass sheet.
