Abstract
A thermoplastic synthetic high polymer sheet including induced tensile stress lengthwise of the sheet which varies in intensity from a maximum along one edge to a minimum along the other edge. The induced tensile stress is frozen in the sheet by maintaining its temperature below a transformation temperature. Upon elevation of the temperature of the sheet above the transformation temperature, as the process of fabrication of a laminated windshield is to commence, the sheet, without further operative forming operations, will deform to conform substantially to the outline of the outer curved lamina of the windshield. The sheet may include a zone along one edge to provide filtering of glare.
