Abstract
Score lines or fracture lines in a glass sheet are opened by advancing the glass sheet along an article movement path into a snapping station with the score lines to be opened extending between the leading and trailing edge of the sheet as it moves along the article movement path. A moving bending moment is applied to the glass sheet along a path transverse to the article movement path. In one embodiment, the bending moment is applied to the glass sheet by a pair of spaced rotatably mounted wheels urging the sheet in a first direction as a rotatably mounted wheel urges the sheet in a second opposite direction.
