    摘要: The present invention relates to a method for unwinding a bobbin (12) of a coiled sheet (13), the method comprising the steps of: providing a bobbin of a coiled sheet, the bobbin having a first rotation axis (17) and comprising a free portion (14) of the sheet unwound from the bobbin, the free portion (14) defining a contact line (16) as a line separating the free portion and the remaining of the coiled sheet (13); providing a roller (30) having a second rotation axis substantially parallel to the first rotation axis (17); putting the roller (30) in contact with the bobbin (12) at the contact line (16); unwinding the sheet from the bobbin (12) pulling the sheet in an unwinding direction such that an angle between the free portion of the sheet and a radius of the bobbin at the contact line is comprised between about 110 degrees and about 150 degrees or between about 200 degrees and about 300 degrees; and while unwinding the sheet from the bobbin keeping the roller in contact with the outer surface of the bobbin. The present invention also relates to a kit to unwind a sheet of material wound in a bobbin.
