METHOD FOR BENDING AND TEMPERING A GLASS PANEL

摘要

The invention relates to a method for bending a glass panel.The glass panel is heated in a heating furnace (1) for bending and tempering and fed in a flat condition from the furnace (1) onto a bending conveyor (4) while the bending conveyor (4) is in a straight configuration. The bending conveyor (4) and the glass panel are arched to a desired curvature while the glass panel travels along the bending conveyor (4). During the arching process, the bending conveyor (4), or at least its upstream end, is arched beyond a desired final curvature of the glass panel, i.e. the bending conveyor (4), or at least its upstream end, is arched with a bending radius (R2) which is smaller than a bending radius (R1) for the desired final curvature of the glass panel. As a result, the end section flatness of the glass panel is eliminated. Finally, the bent glass panel is tempered.
