Abstract:
1. An apparatus for laminating tape on an electrode for a rechargeable battery, the apparatus comprising: a supplying section for supplying the electrode at a constant rate, the electrode comprising a current collector having surfaces on which active materials are coated at distances from each other, the electrode being wound a plurality of times in a roll shape on the supplying section; a first buffering section for carrying the electrode from the supplying section at the constant rate; a laminating section for receiving the electrode from the first buffering section, the laminating section configured to laminate tape on end portions of the active materials after movement of the electrode is stopped in the laminating section and while the supplying section continuously supplies the electrode to the first buffering section at the constant rate; a feeding section for stopping the movement of the electrode for a predetermined time in the laminating section and conveying the electrode from the laminating section at a desired pitch, the feeding section stopping the movement of the electrode in the laminating section while the supplying section continuously supplies the electrode to the first buffering section at the constant rate; a second buffering section for carrying the electrode from the feeding section and conveying the electrode at the constant rate; and a winding section for receiving the electrode from the second buffering section at the constant rate and winding the electrode in a roll shape, wherein the first buffering section comprises: wherein the second buffering section comprises:
