ABSTRACT:
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).
