ABSTRACT:
The present invention provides an adhesive filament-bearing adhesive tape comprising an adhesive substrate adapted to be releasably adhered to a surface to be coated, and a filament releasably adhered to an edge of that substrate, that is useful in trimming a coating applied to a surface. The invention further provides a method of trimming a coating applied to a surface comprising applying to the surface to be coated a masking material to define the area to be coated and a filament of material of sufficient tensile strength to cut the coating material; applying coating material to the surface; allowing the coating material to dry or cure until it obtains sufficient strength to hold a cut edge; and drawing the filament through the coating to cut the coating. Finally, the present invention provides an apparatus for making a filament-bearing adhesive tape comprising means for folding an adhesive substrate along a predefined line; means for applying a filament to the interior of the fold so formed; and means for closing said fold to retain said filament at the edge of the filament bearing tape.
