Abstract
A method and apparatus for making masking tape is provided. A hot melt or thermoplastic adhesive having no added foaming agents, blowing agents, or surfactants is applied to a paper backing having a moisture content, wherein the adhesive is at a temperature near or below the boiling point of water. The adhesive-coated tape is then advanced to a heating device and heat is applied thereto such that the moisture present in the tape is vaporized and dispersed throughout the adhesive to give the adhesive a foam-like quality.
