Abstract
A metal or metal compound coating 6 is deposited on a face of a hot, freshly formed ribbon 1 of glass during the ribbon's forward travel through a coating station 5 between a forming installation 3 and an annealing lehr 4 by contacting the ribbon face with fluid coating precursor material e.g. sprayed from nozzle 17. Preparatory to the coating step, the ribbon 1 is passed through successive thermal conditioning zones comprising a zone 19 in which temperature gradients across the ribbon are reduced and a following zone in which heat is supplied substantially entirely to a surface layer of the glass at the face to be coated by exposing that face to one or more radiant heaters 22 having a black body temperature below 1100.degree. C. to compensate at least partially for the cooling effect of the coating step on the ribbon 1.
