ABSTRACT:
A process and apparatus for shaping a glass sheet according to which the sheet is lifted above the conveying plane by a device for supporting a glass sheet consisting of a box open at the bottom whose opening at the bottom corresponds to the shape of the glass sheet to be grasped and which is slightly smaller than the glass sheet so that, on the edges of the glass sheet, a narrow annular contact surface is formed and so that the partial vacuum prevailing in the box is limited to such a value that the weight of the glass sheet is essentially compensated for, then is applied against a bending form by a current of hot gas directed upward. The process is used in the production of shaped glazings.
