Abstract: A method for the production of glass ribbon portions is provided that includes: transporting a glass ribbon at a velocity v1, wherein the velocity v1 is dependent on the predetermined glass thickness (d1), with the application of a tensile stress parallel to the edges of the glass ribbon, in a plane E1, and cooling the glass ribbon at a cooling rate that is dependent on the predetermined glass thickness (d1), inserting a score on the surface of the glass ribbon in at least one edge area by scoring the glass surface with a scoring tool, wherein the score has an angle a to the transport direction of the glass ribbon, deflecting the glass ribbon in a plane E2 to generate a bending stress and separating a glass ribbon portion with the formation of edges by breaking the glass ribbon on the extension of the score running transversely to the glass ribbon.

Abstract: A method for packing flat substrates, more particularly glass substrates, in a packaging box is provided. The method include the steps of: providing a base part of the packaging box, the base part comprising a lower wall and preferably four side walls, placing a flat substrate directly or indirectly on the lower wall of the base part of the packaging box, placing an intermediate layer directly or indirectly on the placed flat substrate, forming a stack of flat substrates and intermediate layers therebetween by repeating the preceding two steps, and setting a cover part of the packaging box on the base part of the packaging box.
