ABSTRACT:
When an elongate film is initially wound around a core, it is wound under a low winding tension command value T1corresponding to the length of the core. Then, after the tension is progressively increased at a predetermined rate, the elongate film is wound while its tension is gradually lowered from a high winding tension command value T3.
