METHOD AND APPARATUS FOR BENDING AND TEMPERING A GLASS PANEL

摘要

The invention relates to a method and apparatus for bending a glass panel . A heated flat glass panel (G) is fed from a furnace (1) onto a bending con veyor (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). An interpolati ng position-setting for the tempering conveyor s (5) upstream end with respe ct to the tempering conveyor s bending radius is performed in such a way tha t a certain point (6a) at the tempering conveyor s upstream end coincides wi th a certain point (6a) at the bending conveyor s (4) stationary downstream end. This position-setting is performed by moving the tempering conveyor (5) in vertical and horizontal directions and by pivoting the tempering conveyo r so as to change an angle (aø, bø) between its center line of curvature (CL ) and a vertical line (6).
