That is, the processing rollers 21 opposed to each other
The interference between the processing blade 25 and the processing rollers 21a and 21b can be eliminated because the processing blades 25a and 21b enter the clearance groove 26 to prevent interference with each other. As described above, the pair of processing rollers 21
Since the processing blades 25a and 21b are provided at opposing positions without being shifted in the axial direction, the protrusions 2 protruding to the front and back can be formed linearly in the longitudinal direction.

In the above example, the adjacent processing blades 25
24, the shape of the line connecting the tips of
However, when the cutter 24 has three or more processing blades 25 and the shape of a line connecting the tips of the processing blades 25 is a polygon, the polygon is
The shape is not limited to a quadrangle, but may be, for example, a triangle, a pentagon, a hexagon, a heptagon, an octagon, or a nine depending on the shape, size, interval, or the like of the protrusion 2 and the hole 3 formed on the core material 1. A cutter 24 such as a square, a decagon, a dodecagon, and a hexagon is appropriately used. By making the polygon a regular polygon, the intervals between the projections 2 to be formed can be made equal.

Here, what is shown in FIG. 8 is a processing device 15 having a cutter 24 in which the shape of a line connecting the tips of adjacent processing blades 25 is triangular.

In the above example, the core member 1 constituting the negative electrode plate of the secondary battery made of a metal plate such as a nickel foil has been described as an example of the plate member.
