Abstract
In the formation of a metal or metal compound coating on a face of a heated glass substrate during its forward displacement through a coating station by contacting the substrate with at least one stream of droplets comprising a substance or substances from which said coating is formed there is a problem in achieving coatings of high uniform quality. In order to help meet this problem, the droplet stream(s) 23 from spray gun(s) 20 is or are inclined downwardly and forwardly (6) or downwardly and rearwardly towards the substrate 4 and at least one jet of gas is discharged (from nozzle 22) into the environment above the substrate so that it travels in the same (forward or rearward) direction above the substrate 4 and impinges against such droplet stream(s) 23.
