Apparatus and method for degrading a web in the machine direction while preserving cross-machine direction strength

A method for perforate embossing a web without increasing the MD/CD tensile ratio of the web comprising:

• passing a web through an embossing system, wherein the embossing system comprises a first embossing roll having embossing elements and at least a second embossing roll having embossing elements, wherein at least a portion of at least the first or second embossing rolls are crowned, and wherein the first and second embossing rolls define a plurality of perforate nips for embossing and perforating the web;
• and
• wherein at least a predominant number of the perforate nip are substantially oriented in the cross-machine direction.

• and
• wherein the MD/CD tensile ratio of the web is not increased.
