In the fourth step, the pressure bar 164 is advanced to press the selection bars 161. At this time, the pressure is transmitted only to the selection table 161 advanced toward the hydraulic pressure stage 152 to slide the cutter 140 by operating only the selected hydraulic pressure stage 152.

In a fifth step, the cutter 140 cuts the cutting target 40 into the shape of the blade portion 144. The shape of the cut object 40 cut at this time is shown in FIG. On the other hand, according to the steps up to here, it is impossible to cut the cutting object 40 into two parts completely. Therefore, the following steps are further performed to completely cut the cutting object 40.

In the sixth step, the cutting target 40 is moved to move the cutting target 40 cut by the first cutter unit to the third cutter unit.

In the seventh step, the third cutter unit cuts the cutting target 40 by the steps of the third to fifth steps described above.

Through the above steps, the cutting object can be cut or divided into two parts according to the shape of the cutter. On the other hand, even if the cutting surface of the cutting object is not clean, because only a part of the cutting object is cut and the remaining part remains in its original state, the jamming phenomenon of the cutting object does not occur.
