ABSTRACT:
A method is disclosed for attaching an elastomeric film laminate web to the longitudinal side edges of an absorbent article such as a sanitary napkin. The method involves using a system of different adhesive applying mechanisms (that is, glue guns) and different applications of adhesive in a spiral pattern to provide precise control over the pattern and the amount of adhesive applied to bond the web of material to the absorbent article. The method comprises applying a narrow spiral of adhesive to a first portion of the width of the web that is adjacent a first edge of the web; bringing the first portion of the web into contact with a first face of the sanitary napkin so that the remaining portion of the web extends outward beyond the edge of the sanitary napkin; applying a second narrow spiral of adhesive to a second portion of the width of the web adjacent the second edge of the same; folding the second portion of the width of the web onto the second face of the sanitary napkin to wrap the edge of the sanitary napkin; and securing the wrapped web to the sanitary napkin.
