1. 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) and an average center temperature T(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 and has an average thickness Th(B), where Th(B)>1.1 Th(C); (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 D1 from an end of the first side edge surface from the top edge surface to the lower edge surface; (IV) after step (II), restraining at least the second major surface in a vicinity of the first side edge surface at a distance D3 from the end of the first side edge surface using a first mechanical restrainer, where D3<D1; (V) heating at least part of the first peripheral portion of the glass sheet such that an average temperature of the first peripheral portion at a location having the distance D3 from the end of the first edge surface reaches a temperate T(B), where T(B)−T(C)≧40° C.; (VI) after step (V), forming a score-line on the first major surface extending from a vicinity of the top edge surface to a vicinity of the lower edge surface at a distance D2 from the end of the first side edge surface, where D3<D2<D1; (VII) contacting the second major surface with a nosing strip opposing the score-line; and (VIII) after steps (V) and (VI), activating the first mechanical restrainer 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.
