Abstract
Methods of forming front and back waist gasketing elements on an absorbent article are provided. The methods include the steps of providing a web of chassis material and waist gasketing elements, each having a first transverse edge, a second transverse edge, a top and bottom layer. The methods further include bonding the top and bottom layers in closure bond regions, and joining the waist gasketing elements to the chassis to form a strip of final articles. The methods include dividing the strip of final articles between the first and second transverse edges such that a cut separates two final articles, a leading article and a trailing article, wherein each cut is disposed within a closure bond region, forms a back waist edge of the leading article and a front waist edge of the trailing article; and forms an outboard lateral edge of a back waist gasketing element on the leading article and an outboard lateral edge of a front waist gasketing element on the trailing article.
