Abstract
A paper roll and method of manufacturing. The paper roll includes a plurality of sheets spirally wound forming a roll. The roll includes a first end and a second end, wherein the first end forms an inner section. The inner section defines an axial passageway that extends from a first side of the roll to a second side of the roll. An adhesive that can stiffen the inner section joins the plurality of sheets of the first end. The method for manufacturing the paper roll includes winding the plurality of sheets about a low-friction tube to form a roll, applying an adhesive to the plurality of sheets at a first end of the roll forming an inner section having an axial passageway, curing the adhesive configured to stiffen the inner section, and removing the low-friction tube from the roll.
