Claim Text:
1. A method of manufacturing a laminated glazing sheet, comprising the steps of: arranging one or more wires and a busbar on an interlayer formed from a first thermoplastic polymer; arranging the interlayer and the one or more wires and the busbar between sheets of glazing material to provide a glazing assembly wherein the one or more wires extend over and contact the busbar and continue past the busbar to an edge of the assembly; subjecting the assembly to an elevated temperature sufficient to cause at least partial melting of the first thermoplastic polymer; and prior to arranging the interlayer and the one or more wires and the bus bar between the sheets of glazing material and after arranging the one or more wires and the bus bar on the interlayer, applying a solution of a second thermoplastic polymer in a solvent to the one or more wires in a region of the interlayer adjacent said edge and allowing the solvent to evaporate, leaving a film of the second thermoplastic polymer on the one or more wires including a segment of the one or more wires which extend over and contact the busbar, wherein the second thermoplastic polymer may be the same or different from the first thermoplastic polymer, and wherein the elevated temperature is sufficient to cause at least partial melting of the second thermoplastic polymer and fusion thereof with the first thermoplastic polymer.
