Problems solved by technology

However, cutting the elastic strands may damage the elastic laminate, resulting in a relatively poor aesthetic appearance.
In addition, the ends of the cut elastic stands may snap back and in an uncontrolled fashion and consequently may end up in an undesired location within the laminate.
Further, deactivating the elastics in an elastic laminate may weaken the laminate, making the laminate relatively more likely to tear, and / or may otherwise result in control and handling difficulties associated with differential stretch characteristics within the laminate.

Embodiment Construction

[0046]The following term explanations may be useful in understanding the present disclosure: “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).

[0047]An “elastic,”“elastomer” or “elastomeric” refers to materials exhibiting elastic properties, which include any material that upon application of a force to its relaxed, initial length can stretch or elongate to an elongated length more than 10% greater than its initial length and will ...

Abstract

The present disclosure relates to methods and apparatuses for assembling absorbent articles, and more particularly, diapers, each including a chassis connected with front and back elastic belts. Opposing end regions of the chassis are connected with regions of the elastic belts where the elasticity of the elastic belts has been removed or deactivated. As discussed in more detail below, an elastic laminate is formed by intermittently bonding elastic strands between a first continuous substrate layer and a second continuous substrate layer. The elastic strands are then intermittently deactivated by severing the strands in the non-bonded regions to form deactivated regions of the elastic laminate. A plurality of chassis may then be bonded with the elastic laminate, wherein the first or second end regions of each chassis may be bonded with deactivated regions of the continuous elastic laminate.

Description

FIELD OF THE INVENTION[0001]The present disclosure relates to methods for manufacturing absorbent articles, and more particularly, to apparatuses and methods for making elastic belts for diapers.BACKGROUND OF THE INVENTION[0002]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 components created from advancing web or webs are combined with other individual components created from other advancing web or webs. Webs of material and component parts used to manufacture diapers may include: b...
