Method for manufacturing electrode sheets and apparatus therefor

An electrode sheet manufacturing apparatus, comprising:

• a feed reel configured to be wound with an original sheet comprising a belt-shaped metal foil and a plurality of coated portions coated on the belt-shaped metal foil with an electrode material in a lengthwise direction and formed to have a predetermined width with a predetermined uncoated gap;
• a conveying mechanism configured to convey the original sheet from the feed reel;
• a first cutting device arranged in a conveying path of the conveying mechanism, and having a plurality of slitters configured to cut the original sheet into original sheet strips in the lengthwise direction along cutting lines set on the uncoated gaps;
• a rolling device arranged downstream of the first cutting device in a conveying path of the conveying mechanism and configured to press the original sheet strips having been cut by the first cutting device;
• and
• a second cutting device arranged downstream of the rolling device in the conveying path and having a plurality of slitters configured to cut the original sheet strips in the lengthwise direction along cutting lines set on the coated portions.
