Abstract
A method of making an adhesive backed web, wherein the adhesive layer of such web has partially embedded filaments projecting therefrom. The filaments may comprise a thermoplastic material or a hot melt adhesive. The filaments are contacted to a major surface of a liner material then pressed partially thereinto. An adhesive layer, as from an adhesive backed film, is then laminated to the filament-containing liner, allowing the adhesive layer to pick up the filaments.
