Abstract

Described herein is an array of finished products, each finished product in the array having a length relative error of less than 0.81% of a target length, H is disclosed. The finished products, which may be toilet paper and kitchen towels, are formed from transversally cutting elongate logs of convolutely wound web materials.

First claim

What is claimed is:

1. An array of finished products, each finished product in said array having a Percent Compressibility of greater than 3.00%, an actual length ranging from about 10.955 inches to about 11.045 inches, a target length, H, of 11.00 inches, and a length relative error of less than 0.81% of the target length, H, wherein the finished products are paper towels, wherein the actual length is different for at least two finished products of the array, wherein at least one of the finished products of the array of finished products comprises a protruding core and wherein at least one of the finished products comprises a hidden core, and wherein each of the finished products are in a package.

2. The array of claim 1 wherein said length relative error is less than 0.60% of said target length, H.

3. The array of claim 2 wherein said length relative error is less than 0.30% of said target length, H.

4. The array of claim 1 wherein each finished product in said array having a core length relative error of less than 0.81% of a target length, h.

5. The array of claim 4 wherein said core length relative error is less than 0.75% of a target length, h.

6. The array of claim 5 wherein said core length relative error is less than 0.50% of said target length, h.

7. An array of finished products, each finished product in said array having a Percent Compressibility of greater than 3.00%, an actual length ranging from about 10.955 inches to about 11.045 inches, a target length, h, of 11.00 inches, and a core length relative error of less than 1.00% of said target length, h, wherein the finished products are paper towels, wherein the actual length is different for at least three finished products of the array, and wherein at least one of the finished products of the array of finished products comprises a protruding core and wherein at least one of the finished products comprises a hidden core.

8. The array of claim 7 wherein said core length relative error is less than 0.60% of said target length, h.

9. The array of claim 8 wherein said core length relative error is less than 0.30% of said target length, h.

10. The array of claim 7 wherein each finished product in said array having a length relative error of less than 0.75% of a target length, H.

11. The array of claim 10 wherein each finished product in said array having a length relative error of less than 0.50% of said target length, H.

12. The array of claim 11 wherein each finished product in said array having a length relative error of less than 0.30% of said target length, H.

13. A collection of finished products, each finished product in said collection having a Percent Compressibility of greater than 3.00%, an actual length, a target length, h, and a length relative error of less than 2.00% of the target length, H, wherein the actual length is different for at least two finished products of the array and wherein the actual length is the same for at least two finished products of the array, wherein at least one of the finished products of the array of finished products comprises a protruding core and wherein at least one of the finished products comprises a hidden core.

14. The collection of claim 13 wherein said length relative error is less than 0.81% of said target length, H.

15. The collection of claim 13 wherein each finished product in said array has a core length relative error of less than 0.81% of a target length, h.

16. The collection of claim 13 wherein at least two collections of finished products are placed proximate to one another to form an array.

17. The collection of claim 13 wherein each of said finished products are a paper material.
