Abstract
In order to control the thickness of a metal or metal compound coating which is formed on a face of a freshly formed ribbon of hot glass during its travel from a flat glass forming installation by contacting such face at a coating station with a fluid medium or fluid media comprising a substance or substances from which the coating is formed, preparatory to being coated, the glass (4) is thermally conditioned (e.g. selectively or differentially heated) at a thermal conditioning station between the flat glass forming installation and the coating station, so as to eliminate or reduce temperature gradients across the ribbon width to be coated. Apparatus suitable for use in the method comprises means (7-10) for delivering (a) fluid coating medium or media into contact with the glass (4) at the coating station, and means such as heating means (14-16) whereby the temperature of one or more portions of the ribbon width can be conditioned selectively or differentially at a thermal conditioning station located between the flat glass forming installation and the coating station.
