Abstract
A method for manufacturing absorbent articles includes folding each of the absorbent articles about a fold line generally bisecting the article such that front and back waist regions of the articles are positioned in facing relationship, and simultaneously bonding and one of trimming and weakening the front and back waist regions adjacent each opposing side edge of the article to form a pair of fin seams. A bonding and slitting device adapted to form fin seams in absorbent articles includes a first bonding member; and a second bonding member having a contact element configured to cooperate with the first bonding member to bond a front region of the article to the back region to define the fin seams, and a slitter configured to simultaneously act on material outboard of the bonds from both the front and back regions of the article.
