METHOD AND APPARATUS FOR DEPOSITING GRANULES ONTO AN ASPHALT-COATED SHEET

摘要

A method of applying blend drop granules (60) to an asphalt coated sheet (20) includes moving an asphalt coated sheet in a machine direction (13), generating vertically moving blend drops of granules and directing the vertically moving blend drops of granules into contact with a curved conveyor (100). The blend drops are moved along the curved conveyor to change the direction of the blend drops of granules to a generally horizontal orientation in the machine direction. The blend drops are released from the curved conveyor for contact with the asphalt coated sheet.
