Abstract
A process for forming a metal or metal compound coating on a face of a continuously longitudinally moving glass ribbon which comprises the steps of contacting the glass ribbon face while it is at elevated temperature, at a zone along the ribbon path, with a fluid medium containing a substance which undergoes chemical reaction or decomposition to form the metal or metal compound on the face, discharging at least part of the fluid medium against the face in stream formation having (1) a velocity component in the direction of movement of the glass ribbon and (2) an inclination to the face so that the acute or mean acute angle of incidence of the stream formation on the face, measured in a plane normal to the face and parallel with the direction of the glass ribbon movement, is not more than 60.degree..
