Abstract
The present disclosure relates to elastic laminates and methods for assembling elastic laminates that may be used to make absorbent article components. Elastic laminates may include one or more reinforcement layers positioned between unstretched portions of elastic materials and substrates to which the elastic materials are bonded.
Claims20
A taped absorbent article comprising:
- a topsheet;
- a backsheet;
- an absorbent core positioned at least partially intermediate the topsheet and the backsheet;
- a front waist region;
- a back waist region;
- and
- an elastic waist band joined to the front waist region or the back waist region;
- wherein the elastic waist band comprises:
- a first nonwoven substrate;
- a second nonwoven substrate;
- and
- an elastic material positioned at least partially intermediate the first nonwoven substrate and the second nonwoven substrate;
- wherein the first nonwoven substrate partially overlaps itself to create a folded over portion of the first nonwoven substrate, wherein the folded over portion is in direct facing contact with a non-folded over portion of the first nonwoven substrate;
- wherein the folded over portion overlaps a first portion of the elastic material;
- and
- wherein the elastic material is free of overlap from itself.

- and
- a plurality of ultrasonic bonds formed through the first nonwoven substrate, the second nonwoven substrate, and the elastic material;
- wherein the elastic material is free of overlap from itself.
