Abstract
A method of and apparatus for bending and tempering a relatively thin glass sheet while supported horizontally and conveyed along a generally horizontal path comprising heating the glass sheet to its softening point, bending the sheet into the desired curvature, reorienting the bent sheet for further processing along said horizontal path, reheating the sheet to the temperature necessary for proper tempering, and finally, chilling the sheets rapidly below the annealing temperature range of the glass.
