摘要：
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.
