MEANS FOR VAPOR COATING

摘要

An apparatus for vapor coating glass articles where the coating is applied to heated glass articles being carried on a moving conveyor. The apparatus includes a vapor generating cabinet and a connected fuming or vapor coating tunnel which directs the vapor onto the surfaces of the moving glass articles. The vapor is reduced by the heat of the articles to a protective film such as a metallic oxide. The coating tunnel includes means for directing the vapor onto the moving articles and means at opposite ends of the tunnel for both exhausting excess vapor and for forming vapor confining and moisture excluding air curtains.
