Removing heated glass sheets outside a furnace introduces a temperature gradient along the length of the glass. This gradient induces thermal warpage when the glass transfers from a shaping station to a cooling station. The present invention compensates for this warpage by supporting the glass sheet in spaced relation between opposed outline guides having complementary shapes conforming to that desired for the glass sheet marginal portion during the cooling step that heat-strengthens the shaped glass. Care is taken to avoid |
