    HISTORIC
    [001] People use disposable absorbent products in their daily lives, including articles such as incontinence products, bedwetting pants, training pants and diapers. Many manufacturers seek to better meet the demands of users of such products. For example, there is a need to further improve fit, discretion and leak protection for many products. With certain products, such as underwear for adult incontinence and pants for bedwetting, it is important that the garment is felt as much as possible as similar to "regular" underwear, to promote an improved sense of normality for the suffering user incontinence or bedwetting. Many absorbent garments in the pull-on style, similar to conventional pants, currently on the market, such as the one depicted in Fig. 1, employ a product chassis, in which multiple elastic cords are arranged between two layers of non-woven fabric. . The strings extend around the body, so that the elastic forces extend mainly around the user's waist, as is the case with traditional cloth clothes. This design can provide good fit and leak performance, but it has the potential to be further refined in terms of appearance and feel even more similar to "regular" cloth underwear.
    [002] A class of materials that offers the potential to make absorbent garments more "similar to underwear" is that of laminates with elastomeric film. Laminates with elastomeric films are typically elastomeric films arranged between two layers of non-woven fabrics. Films provide elastic properties similar to elastic cords, but offer a smoother and more uniform appearance. Some products currently on the market employ such elastomeric laminates and use a "three-piece" pants construction, in which front and rear body panels are each constructed with laminate with elastomeric film and are connected together via an absorbent insert , which extends between them. Such designs, however, in certain cases, can introduce numerous disadvantages.
    [003] First, many disposable absorbent underwear machines, currently in operation in the industry, employ a "one-piece" approach to forming the product chassis, in which a "full length" outer covering layer is formed before the absorbent insert is fixed. After the full-length outer cover layer is present in the process, front and rear panels are superimposed on the outer cover layer, and elastic cords are placed between the front panel and the outer cover layer, and between the back and the outer covering layer. These large, expensive machines are configured primarily to prepare these "one-piece" pants configurations, and modifying the machines to allow them to prepare "three-piece" pants configurations would be an expensive, complicated and time-consuming undertaking. As a result, the "three-piece" pants currently on the market, which employ desirable elastomeric films, cannot be readily produced with the existing "one-piece" trouser-making assets. Consequently, a solution is needed to enable manufacturers to employ existing "one-piece" trouser-making assets to produce garments that are more similar to underwear, which employ laminates with elastomeric films.
    [004] Secondly, certain "three-piece" designs, currently on the market, which use elastomeric films, suffer from a notable deficiency. The design of certain products results in a region of the pants that is not particularly "similar to underwear". Specifically, a region longitudinally between an elasticized waist panel and an elasticized leg edge is devoid of contraction force, and this region tends to group and grow during use. Such growth and stuffing are undesirable for the consumer, as this condition can impact the product's discretion, as well as negatively affect the fit and aesthetic aspects of the garment.
    [005] Therefore, there is a demand for improved absorbent garment designs that are compatible with existing manufacturing assets in the industry. In addition, there is a demand for improved designs of absorbent garments that employ laminates with elastomeric films. Finally, there is a demand for manufacturing techniques that use existing manufacturing capabilities, but that provide absorbent garments that are more similar to improved underwear.
