  • Multi-roll granule application
    Patent number: 11724281
    Abstract: A method and apparatus for applying or dropping granules onto the asphalt coated surface of a moving sheet in shingle manufacturing is disclosed. The method includes sharing each drop between two or more blend rolls with a subsequent blend roll or rolls applying a partial drop directly on top of partial drops already applied by a first blend roll or rolls. High production speeds can be accommodated since each roll can be operated at slower rotation rates and with slower acceleration and deceleration requirements than would be required if the full granule drop were applied during the same time interval with a single blend roll.
    Type: Grant

    Date of Patent: August 15, 2023
