Abstract
The invention relates to a method to unwind a sheet of material wound in a bobbin, the method comprising: providing a bobbin of a coiled sheet, the bobbin defining an outer surface and comprising a free portion of the sheet unwound from the bobbin; arranging a compressing element on the outer surface of the bobbin, so as to define a contact line, the contact line being the line separating the free portion of the sheet from the rest of the bobbin; pressing by means of the compressing element the outer surface of the coiled sheet at the contact line with a force comprised between about (4) Newton and about (16) Newton; and unwinding the sheet from the bobbin pulling the sheet in the unwinding direction.
