Abstract
Improved method and apparatus for curving and tempering glass sheets, characterized in that a flat sheet of glass, which is to be curved, is supported in a profile-shaped bending mold having a shape-forming surface in it and, while this is the case supported, proceeding to heat said sheet at an elevated temperature sufficient to cause it to soften and warp to conform to said shaping surface, then subjecting the sheet to a cooling atmosphere to reduce its temperature in a controlled manner, and while the sheet is subjected to the cooling atmosphere additional heat is applied to predetermined areas of the sheet to maintain these zones at an elevated temperature until the remaining areas of the sheet are cold below a predetermined temperature.
