Abstract
An apparatus for laminating tape on an electrode for a rechargeable battery includes a supplying section for supplying an electrode having a current collector with surfaces on which active materials are coated at constant distances from each other. The electrode is wound a plurality of times on the supplying section. The apparatus also includes a first buffering section for carrying the electrode from the supplying section at a constant rate and a laminating section for receiving the electrode from the first buffering section and stopping movement of the electrode for a predetermined time. The laminating section laminates tape on end portions of the active materials after stopping the movement. A feeding section conveys the electrode from the laminating section at a desired pitch. A second buffering section carries the electrode from the feeding section at a predetermined rate and a winding section receives the electrode from the second buffering section.
