METHOD FOR DEFORMING A WEB

摘要

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.

主权项

1. A process for deforming a multilayer web, the process comprising the steps of
a) supplying a first layer of a precursor web; b) weakening the first layer at a plurality of locations to create a plurality of weakened, melt-stabilized locations in a first area of the first layer; c) supplying a second layer of the precursor web onto at least the first area of the first layer; d) forming a plurality of first features and a plurality of second features in the precursor web, wherein the first area of the first layer confines a first area of the precursor web, wherein the plurality of first features are apertures formed in the first area of the precursor web coincident with the plurality of weakened, melt-stabilized locations throughout the first layer but not the second layer, wherein the plurality of second features are formed throughout the first and second layers in a second area of the precursor web in the z-direction, and wherein the plurality of first features and the plurality of second features are formed simultaneously.
