Beschreibung
Zusammenfassung:	Disclosed is a device for notching, at an interval of a unit electrode, a continuous electrode sheet in which an electrode active material is applied to one or both surfaces thereof, to form a plurality of unit electrodes from the electrode sheet, the device including a press to press notches on the top and the bottom of the electrode sheet at a set position, and a drawing member arranged at the rear of the press based on a feed direction of the electrode sheet, the drawing member drawing and transporting the electrode sheet by one pitch, a size corresponding to the unit electrode according to operation of the press, wherein, when one of the grippers draws and transports the electrode sheet, the remaining grippers move to a position for drawing.
