Abstract
A method of making coated glass including producing a continuous ribbon of glass, depositing a coating onto a surface of the ribbon during the production process and polishing the coated surface of the ribbon using at least one rotating polishing head. Preferably one or more of the rotating polishing heads have an axis of rotation substantially parallel to the plane of the ribbon. The invention also provides a method of treating glass including polishing a surface of the glass with at least one polishing head wherein the axis of rotation of the polishing head is substantially parallel to the plane of the glass, glass polished according to the methods of the invention and a flat glass production line including a polishing station including at least one rotating polishing head.
Claims20
A method of making coated glass comprising:
- producing a continuous ribbon of flat glass, the ribbon having at least one major surface;
- depositing a coating onto the major surface of the ribbon;
- providing a plurality of rotatable polishing heads, each such polishing head extending only partially across the ribbon, the plurality of polishing heads being arranged in a staggered formation;
- causing the polishing heads to rotate;
- causing the polishing heads to reciprocate along the transverse axis of the ribbon;
- and
- polishing the coated surface of the ribbon with the rotating, reciprocating polishing heads.
