Title:
FOLDING APPARATUS FOR AN ELECTRODE ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2012/008742
Kind Code:
A3
Abstract:
The present invention relates to a folding apparatus for manufacturing a stack/folding-type electrode assembly in which unit cells are sequentially stacked, wherein a separation film is interposed between the unit cells. The folding apparatus comprises: a web supply unit which supplies a web in which plate-type unit cells are arranged at a predetermined interval on a separation film; a winding jig which holds a first unit cell of the web, and which rotates the unit cells such that the unit cells are sequentially stacked and the separation film is interposed between the unit cells; and a rotating shaft correction unit which corrects the location of a rotating shaft of the winding jig in a web-proceeding direction (X-axis direction), wherein the rotating shaft correction unit periodically varies the location of the rotating shaft to the scale that enables compensation for a variation in the X-axis velocity (Vx) of the web that occurs during the winding of the plate-type unit cells.
