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
- a front elastic waist band joined to the front waist region and a back elastic waist band joined to the back waist region;
- wherein the front elastic waist band and the back elastic waist band each comprise:
- 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 elastic material is free of overlap from itself;
- wherein at least one of the front waist band and the back waist band extend outwardly from the absorbent core.

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;
- an elastic material positioned at least partially intermediate the first nonwoven substrate and the second nonwoven substrate;
- and
- a plurality of ultrasonic bonds formed through the first nonwoven substrate, the second nonwoven substrate, and the elastic material;
- wherein the first nonwoven substrate comprises one layer in a first portion and two layers in a second portion, wherein the two layers comprise material of the first nonwoven substrate folded over and in direct facing contact with itself;
- wherein the elastic material is free of overlap from itself;
- wherein the elastic waist band extends outwardly from the absorbent core.

- a reinforcement layer positioned at least partially intermediate the first nonwoven substrate and the second nonwoven substrate, wherein the reinforcement layer comprises a section of material that is distinct from the first nonwoven substrate and the second nonwoven substrate, wherein at least a portion of the reinforcement layer does not overlap the elastic material;
- 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;
- wherein at least one of the front waist band and the back waist band extend outwardly from the absorbent core.
