Abstract
A flexible method of controlling the thickness of a material ribbon, in particular a glass ribbon, as well as an apparatus to implement such a method. To this end, a material in a heated and softened state is drawn into a ribbon and is then cooled down. During the forming process during which the ribbon is formed and drawn, the material is heated. During the forming process thermal energy at least partially in the form of thermal radiation that is emitted from a surface of a heated heating element. that is located opposite the material, is supplied to the material. Heating of heating element occurs at least partially through the energy of a laser beam that is directed onto heating element, thereby locally heating the heating element.
