That is, the protrusions 26 of the upper cutter 20 and the protrusions 36 of the lower cutter 30 serve as guides for precise cutting of the electrode plate 6.
  • At least the upper cutter 20 of the upper cutter 20 and the lower cutter 30 is pushed in the direction of the lower cutter 30 to close the upper cutter 20 and the lower cutter 30.
  • the accuracy of cutting the electrode plate 6 can be further increased by the intersection of the upper cutter 20 and the lower cutter 30, which can contribute more reliably to improve the cutting quality of the electrode plate 6. Will be.
  • the present invention further includes a stopper 62 for more reliably maintaining the close contact state between the upper cutter 20 and the lower cutter 30, whereby the pole plate 6 is formed by the upper cutter 20 and the lower cutter 30.
  • a stopper 62 for more reliably maintaining the close contact state between the upper cutter 20 and the lower cutter 30, whereby the pole plate 6 is formed by the upper cutter 20 and the lower cutter 30.
  • the stopper 62 is designed in consideration of the case where the cutting accuracy of the pole plate 6 is lowered due to the cutting load generated when the pole plate 6 is cut, and when the pole plate 6 is cut due to the stopper 62 structure. Since the deformation of the cutter portion can be prevented, the electrode plate 6 has an advantage of more reliably contributing to ensuring the cutting precision and the cutting quality.
  • the stiffener 72 provided in place of the stopper 62 in the upper cutter 20 can also prevent deformation of the cutter portion due to the cutting load when cutting the pole plate 6, such a stiffener 72 As a result of the deformation prevention of the cutter is the same as above, duplicate description thereof will be omitted.
