## Abstract

A waistband for an absorbent article having a waistband with differential extensibility and/or contraction along the circumference of the waist opening. The waistband may provide a uniform appearance along the circumference of the waist opening. The waistband may have a central zone and at least two outboard zones. The outboard zones of the waistband may be less contracted than the central zone, when the absorbent article is in a relaxed state.

## Claims

### Claim 1

A method of making the waistband, comprising:
elongating a central portion of an elastic material;
elongating an outboard portion of the elastic material;
affixing the elastic material to another material with the central portion elongated and the outboard portion elongated to form a waistband component;
allowing the central portion of the elastic material to relax, thereby creating a waistband component laminate with a contracted central portion; and
applying the waistband component laminate to an absorbent article comprising:
a rear waist portion comprising a rear waistband comprising a topsheet layer and a backsheet layer;
a front waist portion opposite the rear waist portion; and
a crotch portion longitudinally connecting the rear waist portion and the front waist portion;
wherein the waistband component laminate is applied to the rear waist portion so that gathers are formed in the topsheet layer and/or the backsheet layer within the rear waist portion;
wherein an applied percent elongation of the central portion is greater than that of the outboard portion.

### Claim 2 (depends on 1)

The method of claim 1,
wherein each of the rear waist portion and the front waist portion comprise a central zone centered around a longitudinal centerline, a first outboard zone, and a second outboard zone opposite the first outboard zone, wherein each of the first outboard zone and the second outboard zone extend laterally outboard from the central zone;
a first rear ear extending laterally outboard from the central zone, wherein a lateral width of the first rear ear corresponds to the first outboard zone; and
a second rear ear extending laterally outboard from the central zone and opposite the first rear ear, wherein a lateral width of the second rear ear corresponds to the second outboard zone.

### Claim 3 (depends on 2)

The method of claim 2, wherein the waistband component laminate extends from the first outboard zone, across the central zone, and into the second outboard zone, wherein a first portion of the waistband component laminate is disposed on the first rear ear and a second portion of the waistband component laminate is disposed on the second rear ear, and a third portion of the waistband component laminate is disposed on the central zone.

### Claim 4 (depends on 3)

The method of claim 3, wherein the third portion of the waistband component laminate, the second portion of the waistband component laminate, and the first portion of the waistband component laminate each has an applied elongation, and the applied elongation of the third portion is greater than the applied elongation of at least one of the first portion and the second portion.

### Claim 5 (depends on 1)

The method of claim 1, comprising treating the outboard portion of the elastic to render it inelastic.

### Claim 6 (depends on 1)

The method of claim 1, further comprising shirring, gathering, or pleating material in an outboard zone of the waistband component laminate to create rugosities.

### Claim 7 (depends on 1)

The method of claim 1,
wherein the central zone has an installed elongation of between 25% and 35%, and the outboard zone has an installed elongation of between 0% and 10%.
