PROBLEM TO BE SOLVED: To provide electrode winding equipment of secondary batteries, which is made capable of being pulled out easily a winding core from an electrode group, after finishing forming of winding fabrication of the electrode group. SOLUTION: The electrode winding equipment of secondary batteries is constituted with the winding core 6, which forms the electrode group, can rotate in the right and reverse directions, and winds up a separator, the positive electrode, and the negative electrode, spirally by turns according to either the directions of the rotation, a pair of pressing rollers 10, which rotate in one direction with the electrode group G, while pressing the electrode group G inserted between the rollers with a prescribed pressing force during the winding fabrication of the electrode group G, and a one-way clutch 20, which inhibits the inverse rotation of the pressing rollers 10, when the winding core 6 is reversed in the rotation after forming winding fabrication of the electrode group G. |
