METHOD OF MANUFACTURING AUTOMOBILE WINDSHIELD

摘要

An automobile windshield is manufactured by laminating a pair of curved glass sheets with an interlayer film. The interlayer film is manufactured by heating a ribbon interlayer film to an elongatable temperature while continuously transferring the film and winding the interlayer film up on a cone shape drum while elongating the film with a varying elongating distribution in the transverse direction so as to curve the interlayer film in longitudinal direction. The tinted part is formed at upper end in parallel to the edge of the windshield by elongating the ribbon interlayer film with varying elongating distribution in the transverse direction.
