Title of Invention

GRAVITATIONAL BENDING OF GLAZING ELEMENTS ON A MULTIPLICITY OF SUPPORTS

Abstract The invention relates to a glazing element-bending process, comprising: -a first stage involving bending of the glazing element through gravitational depression on a first support providing it with a first central depression, then - a second stage continuing the bending of the glazing element through gravitational depression on a second support, providing it with a second central depression more pronounced than the first and until such time as- the whole of the periphery of the glazing element enters into contact with the said second support, the glazing element being at a sufficiently high temperature to enable its central part to continue to sag following contact ot the whole of the periphery, then - a third stage continuing the bending of the glaz-ing element Through gravitational depression, providing it with a third central depression more pronounced than the second, the- periphery being always in contact with the said second support, then - a fourth stage halting by cooling the depression .of the glazing element and giving it the desired final shape.
