Abstract
Apparatuses are disclosed that include forming selected perforation designs and patterns. The perforation designs and patterns can be formed in linear or nonlinear fashion, can extend in the cross direction or the machine direction and can be formed to complement or match an embossed or printed design on the web. The perforation designs and patterns can be formed utilizing various mechanical perforating techniques.
Claims19
An apparatus for perforating a web in both a cross direction and a machine direction, comprising:
- a discrete web perforator for forming individual perforations extending generally in the cross direction of a web formed of a fibrous material to be converted into a through air dried perforated product;
- at least one additional web perforator for forming individual perforations in the fibrous material extending generally in the machine direction of the web;
- the discrete web perforator and the at least one additional web perforator being positioned and configured to produce a selected perforation design;
- wherein the rotatable roll can rotate while the web is being transported past the discrete web perforator and the at least one additional web perforator to thereby produce the selected perforation design.

- at least one additional web perforator for forming individual perforations in the fibrous material extending generally in the machine direction of the web;
- the discrete web perforator and the at least one additional web perforator being positioned and configured to produce a selected perforation design;
- a cutting die for removing a notch from each of opposite sides of the web at the ends of the individual perforations in the fibrous material extending generally in the cross direction;
- wherein the rotatable roll can rotate while the web is being transported past the discrete web perforator and the at least one additional web perforator to thereby produce the selected perforation design.

- wherein the rotatable roll can rotate while the web is being transported past the discrete web perforator and the at least one additional web perforator;
- a device for embossing or printing an aesthetic pattern on the fibrous material of the web as the web is transported past the discrete web perforator and the at least one additional web perforator;
- and
- a controller causing the discrete web perforator and the at least one additional web perforator to thereby produce the selected perforation design.
