APPARATUS FOR BENDING AND TEMPERING GLASS SHEETS BY DIFFEN- ENTIAL COOLING

摘要

An apparatus for bending and tempering heat-softened glass sheets by differentially cooling the opposite surfaces of the sheets to warp or bow the sheets to desired curvatures. The sheets are conveyed through the tempering section by a series of upper and lower conveyor rolls, each of which is formed of a two-piece construction and curved in a manner providing adequate support for the opposite ends thereof and permitting easy access into the inner regions of the tempering section.
