Abstract
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.
