    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.
