Abstract:
1. A method of wrapping an electrode plate with separators, the method comprising the steps of: cutting a pair of separators into a pair of cut separators; providing a pair of drums in parallel so as to face with each other; conveying an electrode plate to the pair of drums while feeding the pair of cut separators in synchronization with conveyance of the electrode plate such that each of the pair of cut separators is adhered to a corresponding peripheral surface of one of the pair of drums; stacking the pair of cut separators on corresponding surfaces of the electrode plate in synchronization with rotations of the pair of drums; and welding edge portions of the pair of cut separators in synchronization with rotations of the pair of drums.
