  • Patent number: 4319907
    Abstract: In a mold for shaping an apertured glass sheet comprising a shaping plate having a heat capacity more than that of the glass sheet per unit area and a shaping surface complementary to that desired for the glass sheet, areas having less heat capacity per unit area than that of the shaping plate are preferably obtained by cutting apertures in the shaping plate. These apertures or low heat capacity areas are located in the shaping plate in position to face corresponding apertures of the glass sheet to be shaped. When the shaping is performed by press bending the sheet between a pair of molds, preferably both press bending molds of press bending apparatus are apertured. The apertures or areas of low heat capacity in the molds are preferably slightly larger than the apertures in the glass sheet undergoing shaping to improve the stress pattern around the peripheral portion of the glass sheet apertures.
