Abstract
Uniquely perforated web products are disclosed which 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.
Claims18
A web product having a machine direction, a cross direction co-planar and orthogonal thereto, and a Z-direction orthogonal to both the machine and cross directions, the web product having lines of weakness in both the cross direction and the machine direction, comprising:
- a web formed of a fibrous material having one or more plies to be converted into a through air dried perforated product and having a first side, a second side, a cross direction and a machine direction, the web having a plurality of spaced apart and repeating lines of weakness formed of individual deflected or displaced fibers formed by overstraining the individual fibers in the Z-direction of the fibrous material, the lines of weakness extending generally in the cross direction of the web, the web also having at least one line of weakness formed in the fibrous material extending generally in the machine direction of the web, each of the plurality of individual deflected or displaced fibers formed in the fibrous material selectively located relative to adjacent ones of the individual deflected or displaced fibers;
- whereby a selected perforation design is provided on the web comprised of the repeating lines of weakness in the fibrous material generally in the cross direction and the at least one line of weakness in the fibrous material generally in the machine direction.
A web product having lines of weakness comprising:
- a web formed of a fibrous material having one or more plies to be converted into a through air dried product and having a first side, a second side, a cross direction, a machine direction, and a Z-direction, the web having a plurality of spaced apart and repeating lines of weakness formed of individual deflected or displaced fibers formed by overstraining the individual fibers in the Z-direction of the fibrous material and extending generally in the cross direction of the web, a notch removed from each of the first and second sides of the web at the ends of each of the repeating lines of weakness extending in the cross direction of the web, the web also having at least one line of weakness formed of individual perforations in the fibrous material extending generally in the machine direction of the web, each of the plurality of individual deflected or displaced fibers in the fibrous material selectively located relative to adjacent ones of the individual deflected or displaced fibers formed;
- whereby a selected perforation design is provided on the web comprised of the repeating lines of weakness in the fibrous material generally in the cross direction and the at least one line of deflected or displaced fibers formed in the fibrous material generally in the machine direction.
A web product having lines of weakness in both the cross direction and the machine direction, comprising:
- a web formed of a fibrous material having one or more plies to be converted into a through air dried product and having a first side, a second side, a cross direction, a machine direction and a Z-direction, the web having a plurality of spaced apart and repeating lines of weakness formed of individual deflected or displaced fibers formed by overstraining the individual fibers in the Z-direction of the fibrous material extending generally in the cross direction of the web, an aesthetic pattern embossed or printed on the fibrous material of the web, the web also having at least one line of weakness formed of individual perforations in the fibrous material extending generally in the machine direction of the web, each of the plurality of individual perforations in the fibrous material selectively located relative to adjacent ones of the individual perforations;
- whereby a selected perforation design is provided on the web comprised of the repeating lines of weakness in the fibrous material generally in the cross direction and the at least one line of weakness in the fibrous material generally in the machine direction.
