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.
