Patent number: 9925743Abstract: A process for producing glass laminates including at least one sheet of glass having a thickness not exceeding 1.0 mm with reduced optical distortion and shape consistency. A pre-laminate stack of two glass sheets and a polymer interlayer are stacked between two buffer plates that are formed nominally to the desired shape of the laminate mold. The pre-laminate stack is held between the buffer plates while a vacuum is applied to the edges of the pre-laminate stack and the stack is heated to a temperature somewhat above the softening temperature of the interlayer to de-air and tack the interlayer to the two glass sheets forming the desired shaped laminate with reduced optical distortion.Type: GrantFiled: June 12, 2013Date of Patent: March 27, 2018Assignee: CORNING INCORPORATEDInventors: William Keith Fisher, Mark Stephen Friske, Paul George Rickerl, Huan-Hung Sheng
