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.

摘要： 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.

摘要： A mandrel suitable for supporting and unwinding a convolutely wound web material is disclosed. The mandrel has a mandrel shaft with a longitudinal axis, a plurality of mandrel arms extending from the mandrel shaft, and at least one expansion element disposed upon a respective each of the mandrel arms. The mandrel shaft is capable of rotating about the longitudinal axis. Each of the mandrel arms is disposed and rotatable about the longitudinal axis. The at least one expansion element is expandable radially away from the respective mandrel arm relative to the longitudinal axis. The convolutely wound web material is disposable about each of the mandrel arms. Further, the at least one expansion element is expandable into contacting and releasable engagement with the convolutely wound web material. The convolutely wound web material is fixably and releasably disposed about each of the mandrel arms.

摘要： An unwind apparatus for obtaining, loading, splicing, and unwinding convolutely wound rolls of web material and forwarding the web material unwound from each of the convolutely wound rolls uninterruptedly to a downstream apparatus is disclosed. The unwind apparatus provides for a multi-axis robot and an end effector operatively connected to the multi-axis robot. The end effector provides for a stationary motor, a rotational coupling mechanically coupled to the stationary motor, and, a mandrel mechanically coupled to the rotational coupling. The mandrel is capable of releasably engaging the convolutley wound rolls of web material.
