METHOD OF REDUCING WINDSHIELD RESIDUAL STRESSES

摘要

A method of reducing localized tensile stresses in shaped glass sheets formed by sag bending. An insulating member is spaced below a heat softened glass sheet shaped on a shaping rail to thermally insulate the glass from heat reradiated from the shaping rail and support structure during the cooling of the shaped glass sheet and provide more uniform cooling of the entire glass sheet.
