    • A positive electrode plate (8), a negative electrode plate (4), and a separator (7) respectively having lengths required for constituting one spiral electrode group (103) are mounted on individual mount jigs (30, 32, 28) for pulling out or for winding, thereby constituting individual cassettes (29, 31, 27). These individual cassettes (29, 31, 27) are sequentially supplied for, and then mounted on a plurality of group winding head units (20) circulating along a predetermined transportation path. The electrode plates (8, 4) and the separator (7) are wound around a rotationally-driven winding shaft (22) of the group winding head unit (20) while the individual electrode plates (8, 4) supplied from the individual electrode plate cassettes (29, 31) are being positioned at predetermined relative positions on both sides of the separator (7) supplied from the separator cassette (27) in a process for circularly transporting the group winding head units (20).
    • 分别具有构成一个螺旋电极组(103)所需的长度的正极板(8),负极板(4)和隔板(7)安装在用于拉出的各个安装夹具(30,32,28)上 从而构成各个盒(29,31,27)。 这些单独的盒子(29,31,27)被顺序地供应,然后安装在沿着预定传送路径循环的多个组绕组头单元(20)上。 电极板(8,4)和分离器(7)围绕组绕组头单元(20)的旋转驱动的卷绕轴(22)缠绕,而从各个电极提供的各个电极板(8,4) 在圆形运送组卷绕头单元(20)的过程中,板盒(29,31)被定位在从分离器盒(27)提供的分离器(7)两侧的预定相对位置。
