A method of making an absorbent article comprising the steps of: obtaining a carrier web and transporting the carrier web in a machine direction; obtaining a first absorbent core web and a second absorbent core web; serially cutting the first absorbent core web thereby forming a plurality of discrete first absorbent cores each having a first core first cut edge and a first core second cut edge; serially cutting the second absorbent core web thereby forming a plurality of discrete second absorbent cores each having a second core first cut edge and a second core second cut edge; arranging a discrete first absorbent core and a discrete second absorbent core in a longitudinally offset configuration, wherein the first core first cut edge extends longitudinally outboard of one of the second core first cut edge and second core second cut edge, and the other of the second core first cut edge and second core second cut edge extends longitudinally outboard of the first core second cut edge; applying a first deposit of adhesive between the discrete first absorbent core and the discrete second absorbent core, whereby at least a portion of the first deposit of adhesive will contact the carrier web between the carrier web and the discrete second absorbent core longitudinally outboard of the discrete first absorbent core and wherein the first deposit of adhesive does not extend longitudinally beyond the second core first cut edge or second core second cut edge; joining the first absorbent core to the second absorbent core and to the carrier web in the offset configuration, thereby forming a laminate structure web; joining a backsheet web to the laminate structure web thereby forming an absorbent article web; and cutting the absorbent article web into a plurality of discrete absorbent articles.
