A method for the production of glass ribbon portions is provided that includes: transporting a glass ribbon at a velocity v, wherein the velocity vis dependent on the predetermined glass thickness (d), with the application of a tensile stress parallel to the edges of the glass ribbon, in a plane E, and cooling the glass ribbon at a cooling rate that is dependent on the predetermined glass thickness (d), 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 Eto 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.
