  • Publication number: 20210154057
    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.

  • Patent number: 10016320
    Abstract: A wearable article with an extensible fastening member having a fastener proximate its end is disclosed. The fastening member may be highly extensible, and may have construction features and shape characteristics that affect distribution of force components when the fastener is in use, and reduce the chances of buckling or flipping of the fastening member along its edges, and the chances that the edges of the fastener will be lifted away from a surface to which it is attached. The fastener and material forming an accompanying landing zone on the article may be selected to form a fastening combination having performance attributes that provide further resistance to unintended pop-off under wearing conditions.
