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 comprises a first forming frame and a second forming frame , and the swingable center of each of swingable frames , which forms right and left portions of a second forming frame , is located at an intermediate position apart from a separation position from each of fixed frames . By such arrangement, the intermediate glass sheet can be equally supported when the swingable frames are moved along the intermediate glass sheet and the intermediate glass sheet is transferred from the first forming frame onto the second forming frame
