Abstract
A method of bending glass sheets, in which the glass is initially supported in the central part on a bending mold and then heated to a bending temperature, comprising the operations of uniformly heating the glass until the end portions of the glass begin to deviate toward the mold, then progressively increase the temperature of the glass outward toward each end thereof as the curving glass conforms to the curved surface of the mold.
