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 method of making a roofing material, which comprises treating an extended length of substrate roofing material or composite roofing material comprising the steps of:
depositing material substantially in a liquid state onto the surface of said roofing material in a plurality of nail tabs, said material solidifying and bonding to the surface of said roofing material wherein said material is deposited on said roofing material by an engraved pattern print roll.
2. A method of making a roofing material in accordance with claim 1 , wherein said material is substantially a polymer material.
3. A method of making a roofing material in accordance with claim 1 , wherein said nail tabs are elongated strips.
4. A method of making a roofing material in accordance with claim 1 , wherein said material is applied to said engraved pattern from a reservoir positioned in contact with said print roll.
5. A method of making a roofing material, which comprises treating an extended length of substrate roofing material or composite roofing material comprising the steps of:
depositing material substantially in a liquid state onto the surface of said roofing material in a plurality of nail tabs by an engraved pattern print roll;
said material is injected into said engraved pattern on said print roll by a pressurized applicator placed in contact with said pattern; and
solidifying and bonding said material to the surface of said roofing material.
6. A method of making a roofing material comprising the steps of depositing tab material at a plurality of locations substantially made of a polymer material in a liquid state onto a transfer surface, said transfer surface receiving said tab material for deposition onto said roofing material in a plurality of nail tabs.
7. A method of making a roofing material in accordance with claim 6 , wherein said transfer surface is pressed onto said roofing material to deposit said tab material.
8. A method of making a roofing material in accordance with claim 7 , wherein said tab material in a liquid or viscous state is hardened or cured by means of ultra-violet or visible light.
