  • Patent number: 3974914
    Abstract: A package for a roll of continuous sheet material is shown having a first hollow circular core on which the sheet material is wound with a tube within the core. The tube is of greater length than the core so that the ends thereof extend beyond the continuous roll. End plates are provided on opposite ends of the roll and are apertured for receiving the extending sections of the tube. The end plates support the roll so that when two of such rolls, with associated apparatus are stacked, the end plates bear any loading force associated with the stacking. The end plates, the core, the tube and the roll of material are secured in a unitary structure by fasteners attached to the opposing ends of the second tube. A hollow covering member open at both ends is placed over the roll.
