Abstract
Abstract Pressure-sensitive fastening tabs for disposable diapers in which the free end of each tab is folded back transversely on itself with the pressure sensitive adhesive surface on the inside. Disposed between the thus juxtaposed adhesive surfaces is a release sheet having multiple folds at one end adjacent the transverse fold of the tab. The release sheet permits the tab to be unfolded for use when applying the diaper, and the folds in the release sheet provide a handle for removing the release sheet completely from the tab.
