<p>The windscreen consists of two glass sheets (3,6) with an intermediate layer between which tapers in a downward direction and is made from at least two thermoplastic films. One of the films (4) has a tinted filtering strip (2) along its upper edge, while the other (5) has a wedge-shaped cross-section to provide the required angle of taper. The filtering strip has parallel faces, and the angle of taper is provided by the other film, which is shaped by extrusion or stretching. The windscreen is some 0.8 m high, with a radius of curvature of 3.30 m at the top. The plastics film layer with the tinted strip adopts a tapering cross-section when stretched for fitting.</p> |
