| 20090110818 | Shingle With Alternate Granules Under Prime Granules - A method of manufacturing roofing shingles including the steps of coating a continuously supplied shingle mat with roofing asphalt to make an asphalt-coated sheet, the asphalt-coated sheet having at least one prime region, applying alternate granules onto the at least one prime region, applying prime granules over the alternate granules to form a granule-covered sheet, and cutting the granule-covered sheet into shingles. | 04-30-2009 |
| 20090220743 | Roofing Materials Having Engineered Coatings - An asphalt-based roofing material includes a coating having a top portion containing a mixture of asphalt and igneous and/or metamorphic rock particles, while the mat portion of the coating contains a mixture of asphalt and a filler which contains less than 10% igneous and/or metamorphic rock particles. In other embodiments, the top portion but not the bottom portion of the coating meets or exceeds a pliability standard, passes a weathering performance test, or has a high solar reflectance. In another embodiment relating to a laminated roofing material, the top portion but not the bottom portion has viscoelastic properties effective to prevent the coating from sticking to an adjacent shingle in a bundle. The invention also relates to a continuous process of applying first and second coatings to a mat for manufacturing a roofing material. In a first coating operation, a first asphalt-based coating is continuously applied to a first surface of the mat so that the first coating saturates the mat and forms a layer on the first surface. In a second coating operation, a second asphalt-based coating is continuously applied to a second surface of the mat so that the second coating forms a layer on the second surface. The second coating has different properties from the first coating. | 09-03-2009 |
| 20100272553 | Method And Apparatus For Handling Shingles - A method of stacking shingles includes manufacturing a plurality of shingles having a granule covered surface and a bottom surface opposite the granule covered surface. Every other shingle is separated into first and second paths. The shingles in the second path are inverted 180 degrees. A shingle from the first path is positioned onto a shingle from the second path, such that the bottom surfaces of each shingle are engaged, thereby defining a stacked pair of shingles. | 10-28-2010 |
| 20110072752 | SHINGLE WITH INCREASED THICKNESS OF SEALANT - Roofing shingles have a top surface, a bottom surface, a headlap portion, and a bead of tab sealant that is configured to bond to an underlying shingle when the shingle is applied on a roof. The tab sealant has a thickness that causes it to extend beyond a face of the bottom surface of the shingle. The headlap portion has a depression extending horizontally across the shingle when shingle is applied to the roof, the depression being spaced from a top edge of the shingle by a distance that will allow the depression to be aligned with the tab sealant of a complementary shingle when the shingles are assembled in complementary pairs, back to back in a bundle. | 03-31-2011 |
| 20110074066 | Methods of demolding building products from a mold - A demolding apparatus for removing molded building products from a mold has a conveyor assembly to advance the mold in a machine direction. A removal mechanism contacts a dislodged portion of the molded building product and applies a dislodging force to the dislodged portion of the molded building product. | 03-31-2011 |
| 20110229636 | APPARATUS AND METHOD FOR CONTROLLING THE DEPOSITION OF GRANULES ON AN ASPHALT-COATED SHEET - An apparatus for applying granules onto an asphalt-coated sheet includes a granule applicator positioned above an asphalt-coated sheet moving in a machine direction. The granule applicator deposits granules into contact with the asphalt-coated sheet along a contact line substantially perpendicular to the machine direction, thereby defining a granule-coated sheet. A granule deflector plate engages the granule-coated sheet downstream of the contact line such that the granule deflector plate rides on the granules of the granule-coated sheet. | 09-22-2011 |
| 20110250045 | APPARATUS AND METHOD FOR CATCHING AND STOPPING SHINGLES PRIOR TO STACKING - An apparatus for catching shingles includes a shingle receiving apparatus configured to receive a shingle moving at a machine speed and a deceleration assembly configured to decelerate the moving shingle upon the moving shingle's engaging the deceleration assembly. | 10-13-2011 |
| 20110283646 | METHOD OF MANUFACTURING A SHINGLE - A roofing shingle includes a headlap portion and a tab portion. A layer of a first granular material is adhered to a back side of the headlap portion and defines a first surface. A bead of tab sealant extends longitudinally on a back side of the tab portion. A longitudinally extending groove is formed in the first surface of the back side of the headlap portion. | 11-24-2011 |
