Coating hood

Claim 1

Hood apparatus for coating vitreous articles, comprising: hood means comprising a top wall and a pair of side walls extending downwardly from said top wall to define a coating chamber; means operative to convey vitreous articles along a predetermined path through said coating chamber; a first pair of coating fluid spray means operative to direct a coating fluid toward said predetermined path; one of said spray means being adjacent one side wall at a certain location along said conveying path; the other said spray means being adjacent the other side wall and longitudinally offset from said first spray means relative to said predetermined path, so that fluid from said pair of spray means impinges vitreous articles on said conveying means in longitudinally offset pattern so as to avoid fluid flow stagnation; a second pair of coating fluid spray means operative to direct coating fluid toward said predetermined path; one of the spray means of said second pair being at said one side wall and the other spray means of said second pair being at the other side wall longitudinally offset from said one spray means of said second pair; each said spray means comprising a fluid manifold disposed in a niche formed in the adjacent sidewall; at least one spray aperture associated with the manifold to direct a coating fluid spray at a certain nonperpendicular angle toward said predetermined path; and each said niche including a nonperpendicular wall portion permitting unimpeded fluid flow from the manifold associated with that niche.
