A process for deforming a web is disclosed. The steps include forming a plurality of microscopic aberrations in a first layer and/or second layer of a precursor web. The microscopic aberrations comprising sidewalls and an aperture disposed at a distal end of the sidewalls. The first layer extends laterally outboard more than the second layer. The precursor web is advanced to a forming unit. The plurality of macroscopic features is simultaneously formed in the precursor web, including first and second features; the first features are disposed in an area of overlap between the first and second layer; the second features are disposed in an area laterally outboard of the second layer; the microscopic aberrations extend in a first direction from the precursor web; the first and second features extend in a second direction from the precursor web; and wherein the first direction is opposite the second direction.

Method for deforming a web

The present invention relates to a method for fabricating absorbent article having multiple layers, and deformed zones of targeted performance, and colored regions, the method comprising the steps of forming discrete features on at least one layer, printing colored regions on at least one layer, integrating multiple layers to form an absorbent assembly, and cutting the absorbent assembly into individual absorbent articles, wherein the steps are carried out continuously.

Method for fabricating absorbent articles

Methods for deforming a multilayer web are disclosed. Steps of the method include: supplying a first layer of a precursor web; supplying a second layer of the precursor web onto at least the first area of the first layer; forming a plurality of first features and a plurality of second features in the precursor web. The plurality of first features are apertures formed in a first area of the precursor web, and the plurality of second features are formed in a second area of the precursor web in a positive and/or negative Z-direction. The plurality of first features and the plurality of second features are formed simultaneously.

The present invention is directed to methods for deforming a web comprising the steps of supplying a precursor web; weakening the precursor web at a plurality of locations to create a plurality of weakened, melt-stabilized locations in precursor web; and forming a plurality of first features and a plurality of second features throughout the first and second layers of the web in the z-direction, wherein the plurality of first and second features are formed simultaneously.

The present invention is directed to methods for deforming a web comprising the steps of supplying a first layer of a web; weakening the first layer at a plurality of locations to create a plurality of weakened, melt-stabilized locations in the first layer; supplying a second layer of the web onto at least part of the first layer; and forming a plurality of first features in the first layer and a plurality of second features throughout the first and second layers of the web in the z-direction, wherein the plurality of first and second features are formed simultaneously.

Apparatuses and processes for aperturing and stretching a web are disclosed. In one embodiment, the method involves feeding a web into a nip that is formed between at least one pair of intermeshing rolls. The first roll is a raised ridge rotary knife aperturing roll and the second roll is a ring roll; both rolls comprise ridges and grooves. The first roll comprises a plurality of spaced-apart teeth extending outwardly from the top surface of the ridges, said teeth having tips, wherein the top surface of said ridges are disposed between the tips of said teeth and the bottom surface of said grooves. These apparatuses and processes enable a web to be formed which comprises apertures having greater open area than previously achievable with traditional processes and apparatuses.
