Abstract

A method of shaping a region (26) on a glass ribbon (20), the glass ribbon including a softening point, and a thickness (24). The method includes, at a location where the glass ribbon has a viscosity less than or equal to 7x1014 poise: causing the region of the glass ribbon to be at a temperature at or above the softening point temperature; and applying tension (35, 37) to the glass ribbon, across the region, so as to form a necked-down section (27) in the region, wherein the necked-down section has a thickness (28) that is less than the thickness of the glass ribbon on each side of the region. Non-sharp portions (29) may be formed together with the necked-down section. The ribbon may then be broken along the necked-down section to separate portions from one another.
