Abstract
In a process and to an apparatus for bending a glass sheet heated to the bending temperature in a horizontal furnace, through which it is passed by a motor roller conveyor, which passes it into a bending cell where it is kept at an ambient temperature substantially identical to the bending temperature, the glass sheet is immobilized in the bending cell in an upper bending mold perpendicular to an annular countermold surrounding an element for supporting the central part of the glass sheet in the bending cell. The annular countermold is raised in order to press the glass sheet against the upper bending mold.
