Summary:The invention relates to a method and apparatus for bending a glass panel. A heated flat glass panel is fed from a furnace onto a bending conveyor while the bending conveyor is in a straight configuration. The bending conveyor and the glass panel are arched to a desired curvature while the glass panel travels along the bending conveyor. An interpolating position-setting for the tempering conveyor's upstream end with respect to the tempering conveyor's bending radius is performed in such a way that a certain point at the tempering conveyor's upstream end coincides with a certain point at the bending conveyor's stationary downstream end. This position-setting is performed by moving the tempering conveyor in vertical and horizontal directions and by pivoting the tempering conveyor so as to change an angle between its center line of curvature and a vertical line.
