Abstract
A threadlike or ribbonlike elastic strand is provided with a substantially continuous filament of adhesive helically wrapped around the elastic strand. The elastic strand is suitable for use in disposable absorbent products such as diapers and adult incontinent products. Also disclosed is a method and, apparatus for making such adhesive-wrapped elastic strands.
Claims6
