ABSTRACT:
A method for making an absorbent article, such as a sanitary napkin, having tabs. A first series of patches of a hot melt type pressure sensitive adhesive are applied to one side of a double-sided release strip. The release strip is then placed against the central portion of the absorbent article so that the first adhesive patches bond to the central portion. A second series of patches of the adhesive are applied to the other side of the double-sided release strip and tabs are folded over the central portion so that the second adhesive patches bond to the tabs. Since the release strip has been coated with a release agent, such as silicone, on both of its sides, the first and second patches of adhesive bond to the central portion and the tabs, respectively, with greater tenacity than they did to the release strip. When the user removes the release strip prior to use, the first and second adhesive patches remain on the central portion and the tabs. Thus, a hot melt type of pressure sensitive adhesive is applied to the central portion and the tabs without danger that they will be scorched by the heat of the hot melt adhesive as it leaves the glue gun.
