Patent ID: 8820599

Claim:
A process for removing a first peripheral portion of a glass sheet, the process comprising steps of: (I) providing a glass sheet having a first major surface, a second major surface opposing the first major surface, a center region having a center thickness Th(C), an upper edge surface, a lower edge surface, a first side edge surface and a second side edge surface, each edge surface connecting the first major surface and the second major surface, and the first peripheral portion is in a vicinity of the first side edge surface; (II) placing the glass sheet in a predetermined position by securing the first and second major surfaces in a vicinity of the upper edge surface to a suspension device; (III) after step (II), restraining the first and second major surfaces in a vicinity of the first side edge surface at a distance D 1 from an end of the first side edge surface extending from the upper edge surface to the lower edge surface; (IV) after step (III), forming a score-line on the first major surface extending from a vicinity of the upper edge surface to a vicinity of the lower edge surface at a distance D 2 from the end of the first side edge surface, where D 2 <D 1 ; (V) clamping the first and second major surfaces in a vicinity of the first side edge surface at a distance D 3 from the end of the first side edge surface using a first pair of clamps, where D 3 <D 2 ; (VI) contacting the second major surface with a nosing strip opposing the score-line; (VII) after steps (V) and (VI), activating the first pair of clamps to push the first peripheral portion of the glass sheet in a direction from the first major surface to the second major surface such that the first peripheral portion of the glass sheet bends against the nosing strip and separates along the score-line from the center region of the glass sheet.
