CA 2732162
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.
Unité de traitements de surface de verre plat, en particulier sous forme d'un raban ou d'une plaque, notamment par modifications des propriétés chimiques, optiques ou mécaniques ou le dépôt d'une ou plusieurs couches minces, comportant des moyens de chauffage et de refroidissement pour créer un gradient contrôlé de température dans l'épaisseur du verre, des moyens de chauffage de la face à traiter pour que celle-ci soit toujours aux températures requises et pendant les durées nécessaires pour obtenir des traitements efficaces de sa surface et des moyens de refroidissement de la face opposée pour que cette face opposée soit à une viscosité comprise entre 10 13 dPas et 2.3 x 10 10 dPas.
