Abstract
A method is described for making an elasticized absorbent article having a waist opening and a pair of leg openings. First, multiple distributions of elastics are applied on a moving material sheet to form a moving web of an elastic composite. Then, each of a core section and a second material sheet is periodically applied onto the moving web to define a finished web of discrete elastic composite bodies. In subsequent steps, discrete absorbent pants articles are shaped from the finished web.
Claims25
A method of making elasticized absorbent pants having a waist opening and a pair of leg openings, the method comprising the steps of:
- continuously applying multiple distributions of elastics on a moving material sheet to form a moving web of an elastic composite;
- periodically applying a core section onto the moving web;
- applying a second material sheet onto the moving web to define a web of discrete elastic composite bodies;
- and
- shaping the elastic composite bodies into absorbent pants with leg openings and waist openings.
A method of making an elastic composite web from which elastic composite bodies of an absorbent article may be separated, the method comprising:
- conveying a continuous web of material sheet in a longitudinal or machine direction;
- applying multiple continuous distributions of elastics onto the moving web to form a web of elastic composite, whereby the elastic distributions generally extend in the machine direction;
- periodically applying a core section on the moving elastic composite web;
- and
- continuously applying a top material sheet onto the web including the core sections.
An elasticized disposable absorbent article in the form of absorbent pants, the article comprising:
- an elastic composite body having a backsheet, a topsheet, an absorbent core between the backsheet and topsheet, and multiple elastic distributions between the topsheet and backsheet, wherein the elastic composite body has a front end edge, a rear end edge, and two lateral side edges each having a top segment, a bottom segment, and non-linear cut-out section therebetween;
- a waist opening defined by the end edges;
- a pair of leg openings each defined, at least partly, by the cut-out section of one of the lateral side edges;
- and
- a pair of side seams each defined by the joining of the top and bottom segments of one of the lateral side edges;
- and
- wherein the elastic distributions are joined at the side seams to form a substantially annular elastic region about each leg opening.
