| description | A pouch case manufacturing device pack according to an embodiment of the present disclosure includes a fixing unit that fixes a pouch film of a laminated sheet for battery cells; and a punch unit that presses the pouch film so as to form a storage part on the pouch film. The punch unit includes a central punch unit and an outer peripheral punch unit surrounding the central punch unit, the central punch unit presses the central portion of the pouch film, and the outer peripheral punch unit presses the outer peripheral portion of the pouch film. In in a vertical cross section parallel to the pressing direction of the punch unit, a radius of curvature of a corner of the central punch unit is larger than a radius of curvature of a corner of the outer peripheral punch unit. |
