ABSTRACT:
A winding mandrel holds a central portion of a belt-like electrode assembly extending flatly and rotates to form a spiral roll of the belt-like electrode assembly around this winding mandrel. The belt-like electrode assembly includes a first region extending in one direction from the central portion and a second region extending in the opposite direction from the central portion. A first attracting device is disposed at one side of the winding mandrel for attracting the first region of the belt-like electrode assembly. A second attracting device is disposed at the opposite side of the winding mandrel for attracting the second region of the belt-like electrode assembly. A first feeding means is associated with the first attracting means for shifting the first region of the belt-like electrode assembly toward the winding mandrel while adjusting a tension applied to the first region of the belt-like electrode assembly in accordance with a winding speed of the belt-like electrode assembly wound around the winding mandrel. And, a second feeding means is associated with the second attracting means for shifting the second region of the belt-like electrode assembly toward the winding mandrel while adjusting a tension applied to the second region of the belt-like electrode assembly in accordance with the winding speed of the belt-like electrode assembly wound around the winding mandrel.
