Abstract
This specification teaches a method for making an electrically heatable windshield of laminated construction. In the method, a pair of glass templets are cut (10) and they include a long glass templet and a short glass templet. The templets are separated (20) from one another. An opaque ceramic paint is applied (30) to an edge portion of a coatable surface of a selected glass templet and is dried (40) thereon. Bus bars are also applied (50) to and dried (60) on the coatable surface of the long glass templet. The glass templets are united (70) and subjected to a bending operation (80) to form a shaped windshield pair. The long glass templet and short glass templet are separated (90). A transparent electrically conductive coating is applied (100) between the bus bars located on the selected glass templet. The templets are reunited (110) with an interposed laminating interlayer material and thereafter laminated (120) together to achieve a shaped laminated windshield which is heatable by the flow of electrical energy therethrough.
