Abstract
A roll of sheet product, in particular of tissue paper, with a central hole along its winding axis includes a cylindrical reinforcing element onto which the paper is wound. The reinforcing element includes at least one ring joined to the innermost turn of the roll, with a width less than the width of the roll and provided with a means of extracting the ring by pulling substantially along the axis of the roll.
Claims13
A roll having a central hole along its winding axis, the roll comprising:
- a roll of sheet product;
- and
- a cylindrical reinforcing element on which the sheet product is wound,
- wherein the reinforcing element includes a ring having an outer layer attached to and in contact with an innermost turn of the roll of the sheet product, and having an inner layer towards a winding axis of the roll, the reinforcing element having a means for extracting the ring by pulling substantially along the axis of the roll, the cylindrical reinforcing element having a length in a direction of the axis of the roll less than the length of the roll of sheet product.
A roll having a central hole along its winding axis, the roll comprising:
- a roll of sheet product;
- and
- a cylindrical reinforcing element on which the sheet product is wound,
- wherein the cylindrical reinforcing element includes a ring having an outer layer attached to and in contact with an innermost turn of the roll of the sheet product, and having an inner layer towards a winding axis of the roll, and
- wherein the outer layer and the inner layer are glued to each another with a part of the inner layer not being glued to the outer layer to form a portion of the inner layer that is configured to be pulled substantially along the axis of the roll to extract the ring.
A roll having a central hole along its winding axis, the roll comprising:
- a roll of sheet product;
- and
- a cylindrical reinforcing element on which the sheet product is wound,
- wherein the cylindrical reinforcing element includes a ring having an outer layer attached to and in contact with an innermost turn of the roll of the sheet product, and having an inner layer towards a winding axis of the roll, and
- wherein the outer layer and the inner layer are formed by helical turns, the helical turns of the inner layer partially overlapping and not being glued in an overlap area to form a portion of the inner layer that is configured to be pulled substantially along the axis of the roll to extract the ring.
