    • 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.
    • 一种用于精密玻璃辊的方法和装置,其形成在玻璃温度为1000℃或更高的玻璃温度下提供具有垂直于玻璃进料位置的表面温度为约500℃或更高的一对热成型辊的熔融玻璃 。 成形辊使供应的熔融玻璃流稀薄以产生形成的玻璃带。 保持在约400℃或更低或300℃或更低的表面温度的一对冷定型和变形辊位于成形辊的垂直下方。 尺寸和变形辊薄并且织造成形的玻璃带以产生具有期望的质地,厚度和厚度均匀性的尺寸的玻璃带。 尺寸和纹理的玻璃带可以具有1mm或更小的厚度,厚度变化不大于+/- 0.025mm。
