  • Patent number: 7331198
    Abstract: A desired temperature distribution is efficiently formed on a glass sheet by a simple structure without lowering heat efficiency within a furnace. A heating furnace conveys a bending mold of a glass sheet and a radiation-heating device is provided in the heating furnace. A first group of a plurality of heating elements are fixed on an inner wall surface of the heating furnace. A second group of a plurality of heating elements are disposed separably from an inner wall surface of the heating furnace.

  • Patent number: 6357263
    Abstract: In bending a glass sheet, the load applied to an intermediate glass sheet can be equalized to improve the quality of a final glass sheet. For this purpose, a forming ring 1 comprises a first forming frame 15 and a second forming frame 16, and the swingable center of each of swingable frames 19, 20, which forms right and left portions of a second forming frame 16, is located at an intermediate position apart from a separation position from each of fixed frames 17, 18. By such arrangement, the intermediate glass sheet can be equally supported when the swingable frames 19, 20 are moved along the intermediate glass sheet and the intermediate glass sheet is transferred from the first forming frame 15 onto the second forming frame 16.
