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 adhesively secured 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 capable of limiting movement of the strand at the opposing ends, thereby maintaining the integrity of the bond between the substrate and the elastic strand.
