Print methodology for applying polymer materials to roofing materials to form nail tabs or reinforcing strips
View Patent ↗A method of making a composite roofing material and the resulting material by depositing nail tabs made of a thermoplastic, thermosetting, adhesive or elastomer material, in a liquid state, onto the base substrate of the composite roofing material or onto the saturated or coated roofing material, or onto a transfer surface to be pressed or laminated onto the roofing material. A preferred embodiment transfers the nail tabs onto an engraved transfer impression roll and uses a pressurized applicator to inject the viscous tab material into engraved patterns depressed in raised areas of the impression roll., then deposits the material onto the roofing material. A preferred embodiment also includes the thermoplastic or thermosetting material in a liquid or viscous state hardened or cured by either its exposure to the air or by the use of ultra-violet or visible light.
1. A roofing or building cover material, which comprises a substrate roofing material or composite roofing material and tab material in a liquid state deposited through capillary action onto the surface of said roofing or building cover material in a plurality of nail tabs, said tab material solidifying and adhering to the surface of said material wherein said material is deposited on said roofing material by a print roll having an engraved pattern for holding said tab material.
2. A roofing or building cover material in accordance with claim 1 , wherein said tab material contains ultra-violet or visible light curing polymers.
3. A roofing or building cover material, which comprises a base substrate material or a saturated or coated material and a plurality of thermoplastic, thermosetting, adhesive or elastomer tabs pressure adhered onto the surface of the base substrate, saturated or coated material in a plurality of nail tabs, wherein said tabs are deposited on said saturated or coated material by a print roll having an engraved pattern for holding said thermoplastic, thermosetting, adhesive or elastomer tab material.
4. A roofing or building cover material in accordance with claim 3 wherein said thermoplastic, thermosetting, adhesive or elastomer is introduced to said engraved pattern through a pressurized applicator.
5. A roofing or building cover material in accordance with claim 3 wherein said print roll has a circumferential raised portion upon which said engraved pattern is located.
6. A roofing or building cover material in accordance with claim 5 wherein said applicator is positioned against said raised portion to supply said engraved pattern with thermoplastic, thermosetting, adhesive or elastomer material.
7. A roofing or building cover material in accordance with claim 3 further comprising an applicator for delivering said thermoplastic, thermosetting, adhesive or elastomer that maintains a tight seal against said print roll.
