Abstract

A consumer width sized roll comprising wound web material comprising a tail. The tail may comprise a bonding material. The bonding material may be arranged in a novel pattern.

First claim

What is claimed is:

1. A consumer width sized roll, comprising:
a wound web material having a tail end edge, a machine direction, and a cross direction;
a first outer edge and a second outer edge along the machine direction;
a plurality of discrete application sites comprising bonding material disposed along the tail end edge and spaced from the tail end edge at no greater than an MD length, “j,” than 5 mm, the plurality of application sites having an average MD length, “a,” from 10 mm to 50 mm, an average CD width, “A,” from 10 mm to 25 mm and being spaced along the cross direction an average CD width, “J,” from 10 to 25 mm;
wherein a first application site of the plurality of applications sites comprising bonding material is disposed adjacent to the first outer edge and is spaced a CD width, “R,” of from 0 mm to 50 mm from the first outer edge; and
wherein the first application site is equally divided into first and second sections via a dividing line running along the MD, wherein the first section is adjacent to the first outer edge and wherein the first section has a different basis weight than the second section.

2. The roll of claim 1 , wherein the plurality of application sites comprising bonding material disposed along the tail end edge and spaced from the tail end edge at no greater than an MD length, “j,” than 2 mm.

3. The roll of claim 1 , wherein a second application site of the plurality of application sites comprising bonding material is disposed adjacent to the second outer edge and is spaced a CD width, “S,” of from 0 mm to 50 mm from the second outer edge.

4. The roll of claim 3 , wherein a third application site of the plurality of application sites comprising bonding material is disposed adjacent to and/or overlapping with an MD center axis and has an MD length from the tail end edge greater than an MD length from the tail end edge of the first and second application sites.

5. The roll of claim 3 , wherein a third application site of the plurality of application sites comprising bonding material is disposed adjacent to and/or overlapping with an MD center axis and has an MD length from the tail end edge less than an MD length from the tail end edge of the first and second application sites.

6. The roll of claim 1 , wherein the consumer sized roll is a paper towel roll.

7. The roll of claim 6 , wherein the paper towel roll is multiple plies.

8. The roll of claim 6 , wherein the paper towel roll is single ply.

9. The roll of claim 1 , wherein the consumer sized roll is a bath tissue roll.

10. The roll of claim 9 , wherein the bath tissue roll is multiple plies.

11. The roll of claim 1 , wherein the second application site is equally divided into first and second sections along the MD, wherein the first section is adjacent to the second outer edge and wherein the first section has a different basis weight than the second section.

12. The roll of claim 11 , wherein the first section of the first application site has a basis weight of less than the second section of the first application site and wherein the first section of the second application site has a basis weight of less than the second section of the second application site.

13. The roll of claim 1 , wherein a first application site of the plurality of application sites is equally divided into first, second, and third sections via dividing lines running along the CD, wherein the first section is adjacent to the tail end edge and the third section is most distanced from the tail end edge and wherein the second section is disposed between the first and second sections, wherein the first section has a basis weight less than at least one of the second and third sections.

14. The roll of claim 13 , wherein the first section has a basis weight less than the second and third sections.

15. A consumer width sized roll, comprising:
a wound web material having a tail end edge, a machine direction, and a cross direction;
a first outer edge and a second outer edge along the machine direction;
first, second, and third discrete application sites comprising bonding material disposed along the tail end edge;
wherein a first application site comprises bonding material and is disposed adjacent to the first outer edge and is spaced from the tail end edge an MD length, “j-1;”
wherein the second application site comprises bonding material and is disposed adjacent to the second outer edge and is spaced from the tail end edge an MD length, “j-9;”
wherein the third application site comprises bonding material and is disposed adjacent to and/or overlapping with an MD center axis and is spaced from the tail end edge an MD length, “j-5;”
wherein j-5 is greater than j-1 and j-9;
wherein the first application site comprises bonding material is disposed adjacent to the first outer edge and is spaced a CD width, “R,” of from 0 mm to 50 mm from the first outer edge;
wherein the second application site comprises bonding material is disposed adjacent to the second outer edge and is spaced a CD width, “S,” of from 0 mm to 50 mm from the first outer edge; and
wherein each of the first and second application sites are equally divided into first and second sections, wherein the first and second sections are different basis weights.

16. The roll of claim 15 , wherein j-1 and j-9 are a same distance.

17. A consumer width sized roll, comprising:
a wound web material having a tail end edge, a machine direction, and a cross direction;
a first outer edge and a second outer edge along the machine direction;
first, second, third, and fourth discrete application sites comprising bonding material disposed along the tail end edge;
wherein a first application site comprises bonding material and is disposed adjacent to the first outer edge and is spaced from the tail end edge an MD length, “j-1,” and off to a first side of an MD center axis of the roll;
wherein the second application site comprises bonding material and is disposed adjacent to the second outer edge and is spaced from the tail end edge an MD length, “j-9,” and off to a second side of an MD center axis of the roll;
wherein the third application site comprises bonding material and is disposed between the first application site and the MD center axis and is spaced from the tail end edge an MD length, “j-2;”
wherein the fourth application site comprises bonding material and is disposed between the second application site and the MD center axis and is spaced from the tail end edge an MD length, “j-8;”
wherein j-2 is greater than j-1 and wherein j-8 is greater than j-9; and
wherein the first and second application sites are equally divided into first, second, and third sections, wherein the first section is adjacent to the tail end edge and the third section is most distanced from the tail end edge and wherein the second section is disposed between the first and second sections, wherein the first section has a basis weight less than at least one of the second and third sections.

18. The roll of claim 17 , wherein j-1 and j-9 are a same distance and wherein j-2 and j-8 are a same distance.
