Abstract
Unit for the surface treatment of flat glass, in particular in the form of a ribbon or a sheet, especially by modifying the chemical, optical or mechanical properties, or the deposition of one or more thin films, comprising heating and cooling means for creating a controlled temperature gradient through the thickness of the glass, means for heating that face to be treated, in order for it to always be at the required temperatures and for the times necessary for obtaining effective treatments of the surface thereof and means for cooling the opposite face in order for this opposite face to have a viscosity of between 1013 dPa·s and 2.3×1010 dPa·s.
