A bend-breaking system with a cutter wheel is lifted, and the wheel and first and second pressers are rotated in an axial direction by a rotation mechanism so that a first presser is positioned in the edge portion of the glass plate. The second presser is lowered by a lifter and the second presser and first and second supports clamp a main body portion and an edge portion of the glass plate. The second presser and the first and second supports clamp the main body portion and the edge portion, and the second support is lowered by a fourth lifter, and the first presser is lowered by the second lifter to press the edge portion of the glass plate extending outside the outline cut line downward while maintaining the clamping of the main body portion by the second presser and the first support to bend-break the edge portion.

A sheet-like glass element has a thickness less than or equal to 0.5 mm and an edge with an edge face intersecting opposite glass faces along two edge lines. The edge face has strip-like sections with each one adjoining a respective one of the edge lines. The strip-like sections interface along a boundary line that extends between the edge lines. The strip-like sections have a first section with a width ranging from 2 m to 8 m and have a first waviness that is lower than a second waviness of a second strip-like section. The second waviness decreases towards the edge line.
