Apparatus for coating glass

摘要

An apparatus for coating glass with a coating consisting of or containing silicon includes a gas distributor for locating transversely of the path of travel of a glass surface. A gas supply duct supplies coating material in gaseous form and the temperature of the duct is controlled. An elongated open-faced chamber positioned adjacent the glass path of travel communicates along its length with the duct through a gas-flow restrictor that provides gas release from the duct into the chamber at constant pressure along the length of the chamber.
