Abstract
A method of dispensing adhesive onto a stretched elastic strand includes applying a first volume of adhesive onto a first portion of the elastic strand, applying a second volume of adhesive onto a second portion of the elastic strand, and applying a third volume of adhesive onto a third portion of the elastic strand. The second volume is less than the first and third volumes. When the elastic strand is adhered to a substrate to form a personal disposable hygiene product, the first and third portions of the elastic strand define opposing ends of the elastic strand, which are adhered with a larger amount of adhesive to resist creep at the opposing ends. The reduction of adhesive in the second or central portion between the opposing ends significantly reduces the adhesive add on in the personal disposable hygiene product.
