METHOD FOR DEFORMING A WEB

摘要

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.

主权项

1. A process for deforming a web, the process comprising the steps of:
a) providing a precursor web comprising a first layer and a second layer, b) weakening the precursor web at a plurality of locations to create a plurality of weakened, melt-stabilized locations in a first area of the precursor web where both the first layer and the second layer exist; c) forming a plurality of first features and a plurality of second features in the precursor web simultaneously, wherein the plurality of first features are formed coincident with the plurality of weakened, melt-stabilized locations in the first area of the precursor web, and wherein the plurality of second features are formed in a second area of the precursor web where the second layer does not exist.
