ABSTRACT:
A reciprocating crossfire set of rinsing means rinses the surface of a glass sheet while maintaining a uniform thickness of rinsing medium in an area on the glass surface where a subsequent spraying operation is to be carried out. The rinsing means are angled obliquely downward, rearward and outward, and rinse water or other medium is supplied at a rate sufficient to force excess rinsing medium off the side and the trailing edge of the sheet, rather than being delivered into the spray area or accumulated along its trailing edge portion. The uniform thickness of rinsing medium prepares the substrate for receiving a more uniform transparent metal-boron coating in the spraying operation that follows.
