Abstract
A method includes forming a continuous ribbon of glass. The continuous ribbon includes a first surface, a second surface opposite the first surface, a first edge region, a second edge region opposite the first edge region, and a central region extending between the first edge region and the second edge region. Each of the first edge region and the second edge region has a greater thickness than the central region of the continuous ribbon. An indented pattern is formed longitudinally along the first edge region of the continuous ribbon by forming a first series of indentations in the first surface of the continuous ribbon and forming a second series of indentations in the second surface of the continuous ribbon. The indented pattern includes intermediate segments interconnected with one another by webs. Each intermediate segment is thicker than adjacent webs.
