ABSTRACT:
The installation for curving and tempering a glass sheet (1) comprises a first series (3) of shaping members (20) exhibiting a surface (3a) intended to come into contact with one of the faces of the glass sheet (1) and a second series (4) of members including a central surface portion (5) to which at least one movable part (6, 7) is attached. First adjustment devices (10, 11, 12) enable the profile of the surface (3a) of the first series (3) of members (20) to be modified, jacks (8) control the movement of the movable part (6, 7) of the second series (4) of members in a curve parallel to the profile of the surface (3a) of the first series (3) of members (20), and second adjustment devices are suitable for modifying the profile of the central surface portion (5) of the second series of members (4).
