Apparatus and method for degrading a web in the machine direction while preserving cross-machine direction strength
An embossing system for embossing and perforating at least a portion of a web is provided comprising a first embossing roll having embossing elements and at least a second embossing roll having embossing elements, wherein the elements of the first and second embossing rolls define perforate nips for embossing and perforating the web and wherein at least a predominate number of the perforate nips are substantially oriented in the cross-machine direction. Moreover, substantially all of the nips defined by the embossing elements of the first and second embossing rolls can be substantially oriented in the cross-machine direction. Further, the cross-machine embossing elements are at an angle of about 85° to 95° from the machine direction.
1. A perforate embossed web having a plurality of cross-machine direction oriented perforations wherein the embossed web has a tensile ratio of less than about 1.2.
2. The perforate embossed web of claim 1 , further having a transluminance ratio of at least 1.005.
3. The perforate embossed web of claim 2 having a transluminance ratio of at least 1.01.
4. The perforate embossed web according to claim 2 having a transluminance ratio of at least 1.02.
5. The perforate embossed web of claim 1 , wherein a majority of the perforations are in the cross machine-direction.
6. A wet-laid cellulosic perforate embossed web having perforate embossments extending predominately in the cross-machine direction.
7. The wet-laid cellulosic perforate embossed web having perforate embossments extending predominately in the cross-machine direction of claim 6 wherein the perforate embossments extend in the cross-machine direction for at least about 10 mils.
8. The wet-laid cellulosic perforate embossed web having perforate embossments extending predominately in the cross-machine direction of claim 6 wherein the angle between the perforate embossments extending in the cross-machine direction and the machine direction of the web is between 60° and 120°.
9. The wet-laid cellulosic perforate embossed web having perforate embossments extending predominately in the cross-machine direction of claim 6 wherein said perforate embossments extend substantially through the thickness of the web.
10. The wet-laid cellulosic perforate embossed web of claim 6 having a transluminance ratio of at least 1.005.
11. The wet-laid cellulosic perforate embossed web of claim 10 having a transluminance ratio of at least 1.01.
12. The wet-laid cellulosic perforate embossed web of claim 11 having a transluminance ratio of at least 1.02.
