1. A method of unwinding a sheet of material wound in a roll, the method comprising:

■ providing a roll of curled sheet material, the roll defining an outer surface and including a free portion of sheet material unwound from the roll;

■ arranging a compression element on the outer surface of the roll, thereby defining a line of contact, the line of contact being the line separating the free portion of the sheet material from the remainder of the roll;

■ compressing the outer surface of the curled sheet at the line of contact with a force between about 4 newtons to about 16 newtons by means of the compression element; and

■ unwind the sheet material from the roll by pulling the sheet material in an unwinding direction.

2. The method of claim 1, comprising:

■, such that the angle between the free portion of the sheet material and the radius of the roll at the line of contact is between about 90 degrees and about 300 degrees.

3. The method of claim 2, comprising:

■ pulls the sheet material in an unwind direction such that the angle between the free portion of the sheet material and the radius of the roll at the line of contact is between about 110 degrees and about 150 degrees or between about 200 degrees and about 300 degrees, unwinding the sheet material from the roll.

4. The method of claim 2 or 3, comprising:

■ move the position of the compression element when unwinding the sheet material so that the angle between the free portion of the sheet material and the radius of the roll at the line of contact during unwinding is between about 90 degrees and about 300 degrees.

5. The method of the preceding claim, comprising:

■ attaching the compression element to the end of the arm;

■ secure the opposite ends of the arms to pivot points;

■ rotate the arm about the pivot point while unwinding, while holding the compression element at the line of contact.

6. Method according to the preceding claim, wherein compressing the outer surface of the mandrel by means of a compression element comprises changing the position of a mass connected to the compression element.

7. Method according to any one of the preceding claims, wherein the sheet is a sheet of homogenized tobacco material.

8. The method of any one of the preceding claims, comprising:

● selects a value of the force with which to compress the outer surface of the roll by means of the compression element based on one or more characteristics of the roll or the sheet material.

9. A kit for unwinding a sheet of material wound in a roll, the kit comprising:

■ a roll defining an outer surface and comprising a free portion of sheet material unwound from the roll;

■, the device comprising:

a spool holder rotatably holding the spool about an axis;

a compression element positioned on the outer surface of the drum so as to define a contact line, which is a line separating a free portion of the sheet from the rest of the drum;

-pulling means adapted to pull the free portion of the sheet of the log in an unwinding direction;

an impactor adapted to push the compression element against the outer surface of the mandrel with a given force;

a changer associated with the presser, said changer being apt to change the value of said given force on the basis of one or more characteristics of the web or of the sheet.

10. The kit of claim 9, wherein the compression element and the pulling device are correspondingly positioned such that an angle between a free portion of the sheet material in an unwinding direction and a radius of the roll at the line of contact is between about 90 degrees and about 300 degrees.

11. The kit of claim 9 or 10, wherein the compression element comprises a roller, a static slider, or a combination thereof.

12. The kit of any one of claims 9 to 11, wherein the compression element comprises a plurality of rollers all in contact with the outer surface of the roll.

13. The kit of any one of claims 9 to 12, wherein the compression element is movable on an outer surface of the spool.

14. The kit of any one of claims 9 to 13, wherein the given force is radial toward a center of the spool.
