Abstract

A method for separating a thin glass, in which method the thin glass is progressively heated along a path which forms a parting line, wherein the heating of the glass is realized by way of the energy of at least one energy source within an area of action of the energy source on the thin glass, and, by way of a temperature gradient of the glass heated by way of the at least one energy source in relation to the surrounding glass, a mechanical stress is generated in the glass, by way of which mechanical stress, a crack propagates, following the mechanical stress, along the parting line.
