Benefits of technology

[0005]The present disclosure relates to methods for manufacturing absorbent articles, and in particular, methods for making pre-fastened refastenable pant diapers. Aspects of the methods according to the present disclosure relate to the fabrication of refastenable pant diapers wherein discrete chassis are advanced in a machine direction such that the lateral axis is parallel with the machine direction. First side panels are then refastenably connected with the first waist region, and second side panels are permanently connected the second waist regions of the discrete chassis. The methods disclosed herein connect chassis with discrete lengths of side panel material and / or connection zone material, and forms a continuous web of articles formed by intermittently spaced chassis and intermittently spaced side panels bridging the gap between the intermittently spaced chassis. The chassis are then folded in the cross direction parallel to a lateral centerline and the first and second side panels are subsequently bonded together. The article is then subjected to knife cut at or adjacent the bonded regions to create discrete, pre-fastened refastenable pant diapers.

Problems solved by technology

However, introducing discrete elastically extendable components in one or both of the waist regions presents a different challenge with regard to maintaining control and positioning of the advancing discrete elastically extendable components relative to other components, such as an article chassis, can be difficult.
However, including such a removable sheet on manufactured diaper pants may have a negative impact on costs and aesthetics.

Embodiment Construction

[0028]The following term explanations may be useful in understanding the present disclosure:

[0029]“Absorbent article” is used herein to refer to consumer products whose primary function is to absorb and retain soils and wastes. “Diaper” is used herein to refer to an absorbent article generally worn by infants and incontinent persons about the lower torso. The term “disposable” is used herein to describe absorbent articles which generally are not intended to be laundered or otherwise restored or reused as an absorbent article (e.g., they are intended to be discarded after a single use and may also be configured to be recycled, composted or otherwise disposed of in an environmentally compatible manner).

[0030]The term “disposed” is used herein to mean that an element(s) is formed (joined and positioned) in a particular place or position as a macro-unitary structure with other elements or as a separate element joined to another element.

[0031]As used herein, the term “joined” encompasses...

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 382,593, filed on Sep. 14, 2010, which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present disclosure relates to methods for manufacturing absorbent articles, and more particularly, to methods for making pre-fastened refastenable disposable absorbent articles.BACKGROUND OF THE INVENTION[0003]Along an assembly line, various types of articles, such as for example, diapers and other absorbent articles, may be assembled by adding components to and / or otherwise modifying an advancing, continuous web of material. For example, in some processes, advancing webs of material are combined with other advancing webs of material. In other examples, individual components created from advancing webs of material are combined with advancing webs of material, which in turn, are then combined with other advancing webs of material. In some cases, individual compo...
