METHOD FOR MAKING AN APERTURED WEB

摘要

The present invention relates to a method for making an aperture web, comprising moving a micro-textured web through a first member comprising male elements and a second member comprising discontinuous female elements, wherein the male elements are arranged in a staggered pattern, and have a shape to form quadrilateral apertures in the micro-textured web.;The present invention also relates to a method for making an aperture web, comprising forming microtextures on a web, and continuously moving the web through a first member comprising male elements and a second member comprising discontinuous female elements, wherein the male elements are arranged in a staggered pattern, and have a shape to form quadrilateral apertures in the micro-textured web.

1. A method for making an apertured web, the method comprising the steps of:
a) providing a precursor web having a first surface and a second surface opposite to the first surface, comprising a plurality of discrete extended elements on the first surface, the discrete extended elements comprising open proximal ends, open or closed distal ends, and sidewalls, b) providing a forming apparatus for macro apertures comprising a first member and a second member, wherein the first member comprises male elements on its surface and the second member comprises discontinuous female elements on its surface, and c) moving the precursor web through the first and second members so that macro apertures are formed in the precursor web as the male elements and the female elements are engaged, wherein the macro apertures have a quadrilateral shape, wherein the male elements comprising teeth having a shape to form the macro apertures having a quadrilateral shape on the precursor web, and being arranged in a staggered pattern.
