Method and apparatus for forming an irregular pattern of granules on an asphalt coated sheet |
摘要 |
In a method of forming an irregular pattern of granules on an asphalt coated sheet, a flow of granules is discharged toward the sheet. The granules are deflected onto the sheet with a deflector having an irregular surface to form a granule deposit having an irregular pattern. In one embodiment of the method, the deflected granules are controlled with a shield. Apparatus for forming an irregular pattern of granules on an asphalt coated sheet includes a granule applicator for discharging a flow of granules, a deflector having an irregular surface for deflecting the granules, and optionally a shield for controlling the granules.
