METHOD AND APPARATUS FOR MANUFACTURING A GRANULE-COVERED ROOFING MATERIAL |
摘要 |
A method of making granule-covered roofing material comprises discharging granules onto continuously moving asphaltic material, pressing the granules into the asphaltic material, directing light toward the granule-covered asphaltic material, measuring the reflected light from the granule-covered asphaltic material, and responding to the measured reflected light by modifying a process parameter to effect a change in the reflectance of light from the granule-covered asphaltic material.
