Abstract:
A method of winding a tape-like laminated film in a disk form, in which the winding tension force applied to the tape-like laminated film is so controlled as to be 0%/winding meters to +0.10%/winding meters to the tension value at the start of winding in accordance with the length of the tape-like laminated film wound around a core. According to this method, the occurrence of the deformation and the winding breakage of the tape-like laminated film during the transportation and storage thereof can be suppressed.
