Abstract
A method of manufacturing a granule coated asphaltic article comprising the steps of applying liquid asphalt to a reinforcing sheet to create an asphaltic sheet, the asphaltic sheet having a top surface and a bottom surface; bending the asphaltic sheet to form an arcuate top surface of the sheet; and applying a coating of granules over the arcuate top surface of the asphaltic sheet.
Claims22
A method of manufacturing a granule coated asphaltic article comprising the steps of:
- providing an asphaltic sheet, where the sheet has a top surface and a bottom surface, having a plurality of granules deposited on the top surface to provide a first coating of granules on the asphaltic sheet;
- bending the asphaltic sheet to form an arcuated top surface of the sheet;
- and
- applying a second coating of granules over the arcuated top surface of the asphaltic sheet.
A method of manufacturing a granule coated asphaltic article comprising the steps of:
- applying molten asphalt to a reinforcement to create an asphaltic sheet, the asphaltic sheet having a top surface and a bottom surface;
- bending the asphaltic sheet to form an arcuated top surface of the sheet, where the arcuated top surface has an apex;
- and
- applying a plurality of granules to the apex of the asphaltic sheet to form a first coating of granules on the asphaltic sheet.
A method of manufacturing a granule coated asphaltic article comprising the steps of:
- applying a first plurality of granules to a top surface of an asphaltic sheet;
- optionally removing excess and non-adhered granules loosely lying on the top surface of the asphaltic sheet to reveal voids between the applied granules on the asphaltic sheet by the first application of granules;
- bending the asphaltic sheet to form an arcuated top surface of the sheet;
- and
- applying a second coating of granules over the arcuated top surface of the asphaltic sheet to fill the voids between the applied granules on the asphaltic sheet by the first application of granules.
