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.
Claims12
A method for forming a tubular sheet product roll including:
- providing a sheet product roll having a first configuration, a void and a moist portion surrounding the void;
- centering a rotational axis of the sheet product roll on a longitudinal axis of a first tool;
- inserting the first tool comprising a plurality of heated regions 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;
- and
- rotating the first tool inside of the void while heating the plurality of heated regions, wherein the heating of the plurality of heated regions and the rotation of the first tool cause a removal of at least a portion of a moisture from the moist portion.
