Abstract

Embodiments of a compressed and coreless roll of sheet product having a center indicator are disclosed. According to an embodiment of the present invention, a compressed coreless roll of sheet product is provided. The compressed coreless roll of sheet product includes a sheet product having a first end and a second end. The sheet product is wound about an axis beginning with the first end and ending with the second end to partially define an axial cavity along the axis. The first end includes an indicator that is visible when the sheet product roll is compressed such that the axial cavity is substantially collapsed.

First claim

What is claimed is:

1. A method for forming a compressed coreless roll of sheet product having an indicator, the method comprising:
applying an indicator to an end of a sheet product;
providing a roll of sheet product by winding the sheet product about a forming core member starting at the end of the sheet product to which the indicator is applied;
initially compressing the roll of sheet product while still retaining the forming core member thereby facilitating removal of the forming core member;
removing, subsequent to initially compressing the roll of sheet product, the forming core member to provide a coreless roll of sheet product having an axial cavity; and
compressing, subsequent to removing the forming core member, the coreless roll of sheet product such that the axial cavity is substantially collapsed.

2. The method of claim 1 , wherein applying the indicator comprises applying colored water to the end of the sheet product.

3. The method of claim 1 , wherein applying the indicator comprises applying colored adhesive to the forming core member and transferring the colored adhesive to the end of the sheet product.

4. The method of claim 1 , wherein applying the indicator comprises spraying the indicator on the end of the sheet product.

5. The method of claim 1 , wherein applying the indicator comprises printing the indicator on the end of the sheet product.

6. The method of claim 1 , wherein the indicator is visible in the substantially collapsed axial cavity.

7. A compressed coreless roll of sheet product produced by way of:
applying an indicator to an end of a sheet product;
providing a roll of sheet product by winding the sheet product about a forming core member starting at the end of the sheet product to which the indicator is applied;
initially compressing the roll of sheet product while still retaining the forming core member thereby facilitating removal of the forming core member;
removing, subsequent to initially compressing the roll of sheet product, the forming core member to provide a coreless roll of sheet product having an axial cavity; and
compressing, subsequent to removing the forming core member, the coreless roll of sheet product such that the axial cavity is substantially collapsed, wherein the indicator is visible in the substantially collapsed axial cavity.

8. The compressed coreless roll of sheet product of claim 7 , wherein the indicator is colored water applied to the end of the sheet product.

9. The compressed coreless roll of sheet product of claim 7 , wherein the indicator is colored adhesive applied to the forming core member and transferred to the end of the sheet product.

10. The compressed coreless roll of sheet product of claim 7 , wherein applying the indicator comprises spraying the indicator on the end of the sheet product.

11. The compressed coreless roll of sheet product of claim 7 , wherein applying the indicator comprises printing the indicator on the end of the sheet product.

12. The compressed coreless roll of sheet product of claim 7 , wherein applying the indicator occurs prior to winding the sheet product about the forming core member.
