Abstract
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 the 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 Y-axis directional rotary shaft compensation unit to compensate for a position of a rotary shaft of the winding jig in a direction (Y-axis direction) perpendicular to an advancing direction of the web, wherein the Y-axis directional rotary shaft compensation unit periodically changes the position of the rotary shaft in the direction (Y axis) perpendicular to the advancing direction (X axis) of the web to minimize vertical amplitude of the web during winding.
