| 20120183684 | APPARATUS AND METHOD FOR DEPOSITING PARTICLES - A granule applicator for an apparatus and method for applying granules onto an asphalt-coated sheet moving in a machine direction with improved resolution and edge definition of the applied granule patches and blends. In one embodiment a blend drop conveyor has an upper flight urged into a concavity by an outside, third roller. The conveyor is configured to receive granules at a first speed in an area near the convergence of the upper flight and the third roller, and to traject them on a second path at a second speed near the sheet speed of the substrate below. The applicator thus changes the speed and direction of the granules, to cause them to land on the substrate with good edge definition and minimal splatter. | 07-19-2012 |
| 20120183685 | APPARATUS AND METHOD FOR DEPOSITING PARTICLES - A granule applicator for an apparatus and method for applying granules onto an asphalt-coated sheet moving in a machine direction with improved resolution and edge definition of the applied granule patches and blends. One embodiment includes a rotating drum having openings that connect the interior space and an exterior of the rotating member. A granule dispenser is mounted within the interior space of the drum for dispensing granules there. A belt wraps around a major portion of the outside of the drum leaving an uncovered area. As the drum rotates within the belt, the granule openings move between a position closed by the belt and retaining granules by centripetal force and an open position wherein the granules are flung from the drum to a substrate. Doors may be used instead of a belt. | 07-19-2012 |
