A glass sheet processing apparatus includes a first gantry assembly that extends across a glass sheet in a cross-machine direction. The first gantry assembly includes a processing head that moves along a length of the first gantry assembly and includes a laser comprising an optical arrangement positioned in a beam path of the laser providing a laser beam focal line that is formed on a beam output side of the optical arrangement. A second gantry assembly extends across the glass sheet in the cross-machine direction. The second gantry assembly includes a processing head that moves along a length of the second gantry assembly.

Cutting sheets of glass, or other glass substitute materials is provided. In a first step, a sheet is cut in a first cutting station in a working direction (L). Panels obtained from the cut sheet are rotated in their rest plane modifying an angular position thereof with respect to the working direction (L). Downstream of the rotation, a second cutting step and at least a third cutting step in a second cutting station and in at least a third cutting station is performed in series in the working direction (L).

Methods for manufacturing a glass ribbon include moving the glass ribbon along a travel path in a travel direction. Methods include directing a first ribbon portion of the glass ribbon to a winding apparatus to wind the first ribbon portion into a roll. Methods include detaching the first ribbon portion from a second ribbon portion of the glass ribbon. Methods include separating the second ribbon portion into a plurality of separated ribbon portions. Methods include directing a first set of the plurality of separated ribbon portions toward a disposal apparatus to crush the first set of the plurality of separated ribbon portions. Methods include forming a stack with a second set of the plurality of separated ribbon portions. A glass manufacturing apparatus is provided.

A bend-breaking device uses a bend-breaking jig that includes a bend-breaking cutter wheel, which is supported by a bend-breaking cutter holder. The bend-breaking cutter wheel forms a scoring line on a glass plate to be processed. The bend-breaking cutter wheel also forms an outline cutting line on the glass plate and then forms a scoring line in a peripheral area of the glass plate extending outside the outline cutting line. Then, bend-breaking of the peripheral area of the glass plate on which the scoring line is formed is performed. The bend-breaking device changes a rolling direction of the bend-breaking cutter wheel in the peripheral area of the glass plate to a planned direction in which the scoring line to be formed next will extend simultaneously with formation of the scoring line in the bend-breaking processing.

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.
