Abstract:
1. A method for cutting edges of a continuous glass ribbon including a top side and an underside traveling at a velocity, comprising: a longitudinal marking to generate a longitudinal marked line defining at least one edge strip; a subsequent transverse marking; a transverse breaking, comprising, after the longitudinal marking, generating at least one longitudinal crack in at least a substantial part of a thickness of the continuous glass ribbon, from the longitudinal marked line, wherein the longitudinal crack is made to propagate at a velocity roughly equal to and in an opposite direction from the velocity at which the continuous glass ribbon is traveling, and the transverse breaking comes after the generating at least one longitudinal crack; and separating the at least one edge strip from the continuous glass ribbon at the same time as the transverse breaking.
