A method for unwinding/winding a laminar sheet (2) arranged so as to cover an area (a) and forming part of a winding structure (1), which comprises a supporting structure (3) associated with the area and including a cylinder (9) for supporting said laminar sheet that identifies a first longitudinal axis of rotation, drive means (11) for rotating the cylinder around the first longitudinal axis and elastic means (12) cooperating mechanically with the drive means (11) during the unwinding/winding of the laminar sheet. The unwinding of the laminar sheet from the cylinder is due to the effect of the rotation of the cylinder induced by the drive means, while the winding of the laminar sheet onto the cylinder is due to the effect of the recovery of the mechanical energy stored by the elastic means during the unwinding of the laminar sheet.
