    • An assembly is disclosed. The assembly includes a cylindrical sleeve and a length of material that is wound upon itself defining a wound roll. The cylindrical sleeve includes an inner surface and an outer surface. The inner surface of the cylindrical sleeve defines a passage extending through the cylindrical sleeve. The length of material includes an inner surface and an outer surface. A portion of the inner surface of the length of material forms a passage extending through the wound roll. The outer surface of the cylindrical sleeve is secured to the portion of the inner surface of the length of material that forms the passage extending through the wound roll. The wound roll forms an upper axial end and a lower axial end. The wound roll is defined by a length extending between the upper axial end and the lower axial end. The cylindrical sleeve forms a distal end and a proximal end. The cylindrical sleeve is defined by a length extending between the distal end and the proximal end. The length of the cylindrical sleeve is greater than the length of the wound roll to thereby define a first portion of the length of the cylindrical sleeve that extends beyond the upper axial end of the wound roll and a second portion of the length of the cylindrical sleeve that extends beyond the lower axial end of the wound roll. Both of the first portion of the length of the cylindrical sleeve and the second portion of the length of the cylindrical sleeve is defined by a Sheffield Smoothness that is less than 350. A method is also disclosed.
