Are arranged at different positions in the width direction of the metal strip 3, that is, in the direction perpendicular to the paper surface of FIG. 7. As a result, as shown in FIG. 8, the metal band 3 has a punching hole 14a punched by one pair of molds 9, 11 and the other pair of molds 10, 11.
The punching holes 14b punched by 13 are formed in a zigzag shape, and the remaining portion 15 after punching in this way is reduced as much as possible to improve the yield.

[0003]

In such a prior art, two pressing machines 7 and 8 are required to punch the metal strip 3 in two rows in a zigzag pattern at different positions in the width direction. A large occupied space must be secured in order to install these press machines 7 and 8, and two press machines 7 and 8 must be installed.
There is a problem that the cost for purchasing, operating and maintaining the equipment becomes expensive.

Therefore, an object of the present invention is to reduce the purchase cost and maintenance cost of a press machine and the occupied space without reducing the yield of processing. It is to provide a processing device.
