PROCESS AND APPARATUS FOR COATING GLASS

摘要

In the formation of a metal or metal compound coating on a face of a heated glass substrate during its forward displacement by contacting such face, at a coating station with at least one stream of droplets comprising one or more substances from which the coating is formed there is a problem in forming uniform high quality coatings which are free from structural defects. To help reduce this problem, the stream(s) of droplets is or are repeatedly displaced along a transverse path across the substrate, and gas is propelled unidirectionally forwardly or rearwardly across the transverse path, out of line with the droplet stream(s).
