Print methodology for applying polymer materials to roofing materials to form nail tabs or reinforcing strips
A method and apparatus for applying nail tabs to roofing and building cover materials involving the steps of depositing tab material onto the surface of the roofing or building cover material, during or after its manufacture, resulting in a plurality of nail tabs from a lamination roll, and bonding the tabs to the surface of the material by pressure between the lamination roll and said surface. The method also encompasses depositing the tab material or pre-formed tabs by a pressure roll in contact with said surface. The tabs preferably are made substantially of a polymer material and may be hardened or cured by ultra-violet or visible light. The tabs may also be pre-formed and have adhesive backing.
1. A method of making a roofing or building cover material, which comprises treating an extended length of substrate, comprising the steps of:
depositing tab material onto the surface of said roofing or building cover material at a plurality of nail tabs from a lamination roll, said tab material bonding to the surface of said roofing or building cover material by pressure between said roll and said surface.
2. A method of making a roofing or building cover material in accordance with claim 1 , wherein said tab material is substantially a polymer material.
3. A method of making a roofing or building cover material in accordance with claim 1 , wherein said tab material is hardened or cured by ultra-violet or visible light.
4. A method of making a roofing or building cover material in accordance with claim 1 , wherein said nail tabs are formed in a continuous strip.
5. A method of making a roofing or building cover material in accordance with claim 1 , wherein said tab material is deposited on said lamination roll from an engraved print roll positioned in contact with said lamination roll.
6. A method of making a roofing or building cover material in accordance with claim 1 , wherein said tab material is pre-formed before contact with said lamination roll.
7. A method of making a roofing or building cover material comprising the steps of first depositing nail tab material at a plurality of locations on said roofing or building cover material, said nail tab material is substantially made of a polymeric material, and subsequently pressure adhering said nail tab material into nail tabs on said roofing or building cover material with a pressure roll.
8. A method of making a roofing or building cover material in accordance with claim 7 , wherein said pressure roll has an engraved pattern that presses said tab material in a pre-determined shape.
9. A method of making a roofing or building cover material in accordance with claim 7 , wherein said tab material, while existing in a liquid or viscous state, is hardened or cured by means of ultra-violet or visible light.
