Abstract:
It is now possible to economically produce, in series production, automotive glazing that has complex small radii feature lines (30). Such feature lines (30) are desirable as they can improve the stiffness of the glazing as well as contribute to the overall aesthetic and differentiation of the vehicle, allowing body lines to blend into and continue in the glazing. However, traditional automotive laminating methods do not lend themselves well to this type of product. Typically, the offset between the mating surfaces of the laminate must be very uniform. Such uniformity is difficult to achieve when producing small radii features. Rather than bending multiple layers with small radii feature lines that can be nested and subsequently laminated using standard plastic automotive interlayers, the invention makes use of a two part method for laminating, a dry lamination process and a wet lamination process, which requires only that the feature lines (30) be present in the outer glass layer (201).
