Abstract

A method for forming a tubular sheet product roll includes providing a sheet product roll having a first configuration and a void, centering a rotational axis of the sheet product roll on a longitudinal axis of a first tool, and inserting the first tool into the void of the sheet product roll to define an inner diameter of the void and to form the sheet product roll having a second configuration different from the first configuration.

Claims (21)

1. A method for forming a tubular sheet product roll including:

providing a sheet product roll having a sheet product wound on a removable core, the removable core having a first distal end, a second distal end and a longitudinal outer surface, wherein the removable core is formed from the wound sheet product;

centering a rotational axis of the sheet product roll on a longitudinal axis of a first tool by slidably moving a plurality of dogs toward a center reference point such that a surface of the dogs contacts the sheet product roll and moves the rotational axis of the sheet product roll to the center reference point; and

engaging the first distal end of the removable core with the first tool and translating the first tool along the rotational axis of the sheet product to slidably move the removable core relative to the sheet product roll to expose a portion of the longitudinal outer surface of the removable core,

wherein the first tool is a mandrel that is cylindrical with a flat head.

2. The method of claim 1 , wherein the removable core is cylindrically shaped.

3. The method of claim 1 , wherein the method further includes slidably removing the entire removable core from the sheet product roll.

4. The method of claim 1 , wherein the method further includes further engaging the first distal end of the removable core with the first tool to slidably remove the entire removable core from the sheet product roll.

5. The method of claim 1 , wherein the mandrel is rotationally fixed such that it does not rotate relative to the sheet product roll.

6. The method of claim 1 , wherein the mandrel is thermally uniform such that it does not have heated regions.

7. A method for forming a tubular sheet product roll including:

providing a sheet product roll having a sheet product wound on a removable core, the removable core having a first distal end, a second distal end and a longitudinal outer surface, wherein the removable core is formed from the wound sheet product;

centering a rotational axis of the sheet product roll on a longitudinal axis of a first tool by slidably moving a plurality of dogs toward a center reference point such that a surface of the dogs contacts the sheet product roll and moves the rotational axis of the sheet product roll to the center reference point; and

engaging the first distal end of the removable core with the first tool and translating the first tool along the rotational axis of the sheet roll product to slidably move the removable core relative to the sheet product roll to expose a portion of the longitudinal outer surface of the removable core; and

gripping the exposed portion of the removable core and slidably removing the entire removable core.

8. The method of claim 7 , wherein gripping the exposed portion of the removable core comprises gripping the exposed portion with an automated second tool.

9. The method of claim 7 , wherein the removable core is cylindrically shaped.

10. The method of claim 7 , wherein the method further includes further engaging the first distal end of the removable core with the first tool to slidably remove the removable core from the sheet product roll.

11. The method of claim 7 , wherein the first tool is a mandrel that is cylindrical with a flat head.

12. The method of claim 11 , wherein the mandrel is rotationally fixed such that it does not rotate relative to the sheet product roll.

13. The method of claim 11 , wherein the mandrel is thermally uniform such that it does not have heated regions.
