ABSTRACT:
This specification teaches a method of manufacturing a curved windshield with an electrically conductive film thereon. The method includes the steps of placing an electrically conductive film, an oxidizable metal layer, and an oxidized metal layer in layered relationship on a flat glass sheet. A glass templet is cut from the coated sheet and electric bus bars are applied and dried on the electrically conductive film on the coated glass templet. A glass templet is cut from an uncoated glass sheet and the two so-formed templets are united with the coating of the one sheet exposed to the ambient. The glass sheets are heated and bent into curved configuration. Thereafter, a laminating interlayer is placed between the glass templets and the glass templets are laminated together.
