An apparatus for dispensing granules onto a moving asphalt coated sheet includes first and second granule feed chambers containing granules that are fed to a discharge slot by first and second pockets. The pockets are formed in a slidable divider positioned between the feed chambers and the discharge slot. The divider is slid between a first position and a second position by a fluid powered actuator via an actuator rod. In the first position, the first pocket is in communication with the first granule feed chamber to receive granules from the feed chamber and the second pocket is in communication with the discharge slot for discharging the granules contained in the second pocket. In the second position the first pocket is in communication with the discharge slot for discharging the granules contained in the first pocket and the second pocket is in communication with the second feed chamber to receive granules from the feed chamber.

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.

Method and apparatus for manufacturing a granule-covered roofing

A method and apparatus for manufacturing roofing shingles having tabs and cutouts comprises a cutting cylinder for engaging a membrane and cutting it into continuous strips, where the circumference of the cutting cylinder and the length of the shingle have a common factor other than the length of the shingle, and an endcut cylinder for cutting the continuous shingle membrane strips into discrete roofing shingles, so that the pattern of tabs and cutouts will repeat itself periodically.

Manufacturing roofing shingles

An adhesive is provided for adhering roofing shingles wherein the adhesive is a blend of asphalt, an elastomer, a tackifying resin and a petroleum oil.
