ABSTRACT:
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 said 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 (e.g. from spray gun 20) is or are repeatedly displaced along a transverse path (defined by guide 15) across the substrate (4), and gas is propelled (e.g. from discharge nozzles 24) unidirectionally forwardly or rearwardly across said transverse path, out of line with the droplet stream(s).
