摘要 |
Disclosed herein is a folding device to manufacture a stacked/folded type electrode assembly having unit cells sequentially stacked in a state in which a separation film is disposed between the respective unit cells, the folding device including a web supply unit to supply a web having plate-shaped unit cells arranged at a top of a separation film at predetermined intervals, a winding jig to rotate the unit cells while holding a first one of the unit cells of the web so that the unit cells are sequentially stacked in a state in which the separation film is disposed between the respective unit cells, and a rotary shaft compensation unit to compensate for the position of a rotary shaft of the winding jig in an advancing direction of the web (X-axis direction), wherein the rotary shaft compensation unit periodically changes the position of the rotary shaft to compensate for the change in X-axis velocity (Vx) of the web caused during winding of the plate-shaped unit cells, thereby uniformly maintaining tension of the web. |
