<p>A glass sheet is bent to a required curvature between two relatively movable complementary bending dies which deform the glass sheet, which is heated to a temperature at which it is pliable. The respective overall heat losses from the two major surfaces of the glass sheet are adjusted during the bending operation so as to be substantially equal. For example, heat loss to one die may take place predominantly by conduction and the temperature of this die may be controlled, by means of heaters, to regulate the conductive heat loss associated with this die and effect the required heat loss balance.</p> |
