Abstract
In a method of forming a pattern of granules on an asphalt coated sheet moving in a machine direction, a flow of separate first granules and second granules is discharged onto the sheet. The flow of granules is rotated to form a pattern of first and second granules on the sheet that changes along the machine direction. Another embodiment of the invention provides a method of forming a pattern of granules, in which the flow of granules is oscillated in a direction transverse to the machine direction. The flow of granules can also be discharged intermittently onto the sheet.
