    • A laminated vehicle glazing comprising a first ply of a glazing material and a second ply of a glazing material having a substantially co-extensive ply of an interlayer material laminated there between, at least a portion of the ply of interlayer material having a wedged cross-section, wherein the ply of interlayer material is pre-shaped by stretching such that either: (a) when the wedge angle is calculated at a plurality of points across the glazing, by taking measurements of a deflection of a laser beam as it passes through the glazing, the standard deviation in the magnitude of the wedge angle of the wedged portion is less than 0.05 mrad; or (b) when a grid pattern is projected onto the glazing, the standard deviation in the displacement between observed primary and secondary images of portions of the grid is less than 0.85 mm.
    • 一种层压车辆玻璃窗,其包括玻璃材料的第一层和玻璃材料的第二层,其具有层压在其间的中间层材料的基本上共同的帘布层,至少部分中间层材料层具有楔形横截面, 其中中间层材料层通过拉伸预成形,使得:(a)当在穿过玻璃窗的多个点处计算楔角时,通过测量激光束通过时的偏转的测量 玻璃窗,楔形部分的楔角的大小的标准偏差小于0.05mrad; 或(b)当网格图案投射到玻璃窗上时,网格部分的观察到的主要和次要图像之间的位移的标准偏差小于0.85mm。
