Abstract
A process and apparatus for precision glass roll forming a supply of molten glass at a glass temperature of 1000° C. or higher with a pair of hot forming rolls having a surface temperature of about 500° C. or higher located vertically below the glass feed. The forming rolls thin the supplied stream of molten glass to produce a formed glass ribbon. A pair of cold sizing and texturing rolls maintained at a surface temperature of about 400° C. or lower or 300° C. or lower is located vertically below the forming rolls. The sizing and texturing rolls thin and texture the formed glass ribbon to produce a sized glass ribbon having a desired texture, thickness and thickness uniformity. The sized and textured glass ribbon may have a thickness of 1 mm or less that varies in thickness by no more than +/−0.025 mm.
