PROBLEM TO BE SOLVED: To provide a winding device reducing cost by minimizing wasteful parts, reducing the size of a product, reducing a winding time and the like, and to provide a winding method. SOLUTION: Two separators 3, 4 are pulled to a predetermined position, positive electrode foil 5 is guided to a predetermined position to be sandwiched between the separators 3, 4, and a winding core 22 is projected. The projecting length X1 of the positive electrode foil 5 and the projecting length of the separators 3, 4 are set nearly a half of winding core width W and not larger than the winding core width W, respectively. When a winding core 22 is rotated at 180°, negative electrode foil 6 is guided to be sandwiched between the separators 3, 4 in the halfway of winding. The length X2 of the guided negative electrode foil 6 is nearly a half of the winding core width W. The total of the length X2 and the length X1 is set to be smaller than the winding core width W. Thereafter, the winding core 22 is rotated at a high speed. COPYRIGHT: (C)2011,JPO&INPIT |
