Methods and Apparatuses for Assembling Elastic Laminates with Different Bond Densities for Absorbent Articles

The methods herein relate to assembling an elastic laminate with a first elastic material and a second elastic material bonded between first and second substrates. During assembly, an elastic laminate may be formed by positioning the first and second substrates in contact with stretched central regions of the first and second elastic materials. The elastic laminates may include two or more bonding regions that may be defined by the various layers or components of the elastic laminate that are laminated or stacked relative to each other. In some configurations, a first plurality of ultrasonic bonds are applied to the elastic laminate to define a first bond density in the first bonding region, and a second plurality of ultrasonic bonds are applied to the elastic laminate to define a second bond density in the second bonding region, wherein the second bond density is not equal to the first bond density.

Deformed web materials are disclosed. The web materials have discrete deformations formed therein. The deformations may be features in the form of portions of a web with apertures therein, protrusions, depressed areas, and combinations thereof. These features may extend out from the surface on one side of the web, or from both of the surfaces of the web. Different features may be intermixed with one another.

Bonding Apparatus and Method

The present disclosure relates to methods and apparatuses for mechanically bonding substrates together. The apparatuses may include a pattern roll including a pattern element protruding radially outward. The pattern element includes a pattern surface and includes one or more channels adjacent the pattern surface. The pattern roll may be positioned adjacent an anvil roll to define a nip between the pattern surface and the anvil roll, wherein the pattern roll is biased toward the anvil roll to define a nip pressure between pattern surface and the anvil roll. As substrates advance between the pattern roll and anvil roll, the substrates are compressed between the anvil roll and the pattern surface to form a discrete bond region between the first and second substrates. As such, during the bonding process, some yielded substrate material flows from under the pattern surface and into the channel to form a channel grommet region.
