Estimating the term…
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.
A method of making a roofing or building cover material, which comprises treating an extended length of substrate comprising the steps of:
A method of making a roofing or building cover material comprising the steps of depositing nail tab material at a plurality of locations, said nail tab material is substantially made of a polymer material in a substantially liquid state, and pressure adhering said nail tab material into nail tabs on said surface with a pressure roll.
A material, which comprises a substrate or a composite material, and a tab material substantially made of a polymer material deposited onto the surface of said material at a plurality of nail tab locations, said tab material solidifying and adhering to the surface of said base substrate or composite material, wherein said tab material is formed into nail tabs by a pressure roll in contact with said substrate or composite material.
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 deposited onto the surface of the base substrate, saturated or coated material at a plurality of nail tabs, wherein said tabs are deposited on said substrate, saturated or coated material by a lamination roll that has pre-formed nail tabs positioned thereon.
