Opened.

Thereafter, although not shown, the movable blade device 5 at the forward limit is retracted through expansion and contraction of the piston rod 5600 of the pneumatic cylinder 5 6, and the operation to reach the reverse limit is finished as it is.

However, in general, when the raw material W exists between the two blades (including the regenerated bark W 1 in part), the movable blade device 5 moves forward again, and the same cutting operation as described above is performed. Repeat the work. That is, when there is a raw material W between the two blades, this movable blade The device 5 is repeatedly moved forward and backward. In the case where there is no raw material W between the two blades, in principle, the new raw material W is charged toward the input opening 13 as described above in a retreat limit state. Further, in this example, the fixed knife device 4 is movable with the transfer shaft 40 as a fulcrum, and the pressing member 45 that can be moved up and down and fixed, and the pressing member 45 are brought into contact with each other (fixed knife support) It is composed of triangular pieces (triangular shape with the upper part being higher and the lower part being lower) provided on the outer surface side 4 1 4 of the part 4 1. That is, by moving the pressing member 4 5 upward, the piece member 4 6 is pressed, the fixed knife device 4 is moved forward, and moved downward, similarly, the fixed knife device 4 is It is configured to be awarded a method of construction. The movement of the fixed blade device 4 is an example, and there may be a cylinder as an example. Explanation of symbols
