Abstract
A method of separating a transparent mother sheet includes contacting a first surface of the transparent mother sheet with an open ended pressure assembly including a pressure vessel shell, thereby forming a shell cavity defined by the first surface of the transparent mother sheet and the pressure vessel shell, where the transparent mother sheet comprises a damage path. The method also includes removing gas from the shell cavity through a fluid removal outlet extending through the pressure vessel shell to reduce a cavity pressure in the shell cavity, thereby applying stress to the damage path to separate a portion of the transparent mother sheet along the damage path.
