The Granule Press Module works by applying uniform, controlled pressure to the shingle surface immediately after granules are dropped onto the asphalt-coated mat. As the mat moves steadily through the line, it passes beneath a press system that makes direct contact with the granules, pressing them into the asphalt while it is still warm and pliable. This pressing action helps the granules seat to a consistent depth across the shingle surface without shifting their pattern or distribution.
By pressing the granules into the asphalt at this precise point in the process, the module helps stabilize the granule layer before the shingle cools and moves downstream. This reduces loose granules, improves surface uniformity, and supports long-term granule retention through cutting, packaging, shipping, and installation. Integrated directly into the continuous production flow, the Granule Press Module performs this function consistently and repeatably, supporting reliable shingle quality without adding unnecessary complexity to the line.
