The cylindrical body 44 can be rotated by a small amount with respect to the bracket 49 about the axis thereof. Thereby, the angle of the cutter 34 can be adjusted. After the adjustment, the two are fastened by the lock handle 59.

The cutting device 1 configured as described above has the following operational effects. First, adjustment of the cut amount with respect to the roll can be performed by extending and retracting the piston rod 14 of the cylinder 11 of the cut amount adjusting device 4 as described above. That is, by changing the center position of the eccentric shaft 25 that can support the mounting portion 15 of the cylinder 5 by extending and contracting the piston rod 14, the final arrival position of the piston rod 17 without changing the stroke of the cylinder 5. Can be changed. Thereby, the rear plate 58 supporting the plurality of cutter devices 27 is provided.
The total lifting amount, that is, the cutting amount for all the rolls of the cutter device 27 can be adjusted.

In addition, in spite of the adjustment by the above method, when the cutting amount of one cutter device 27 is large (or small) due to a mounting error or the like, the above-mentioned vertical position adjusting bolt 42 is optionally set. And the slide shaft 51 is moved up and down to rotate the
Only the vertical position of 7 can be adjusted.

Next, the inclination angle of the cutter 34 with respect to the roll can be adjusted by extending and retracting the piston rod 28 of the air cylinder 7 to incline the entire rear plate 58 supporting the plurality of cutter devices 27. Therefore, by inclining the entire rear plate 58,
The inclination angles of all the cutter devices 27 can be adjusted.

Further, since the rear plate 58 is supported by the protruding piece 19A by the support shaft 33 so that the rear plate 58 can be inclined about a point coinciding with the cutting edge of the cutter 34, the cutting pitch of the roll may vary. Can be prevented.

In the case where the inclination angle of only one cutter device 27 is large (or small) due to a mounting error or the like despite the adjustment by the above-described method, the above-described support shaft 3 is used.
It is also possible to rotate the cutter 7 in any direction with respect to the arm 53 and adjust the cutting edge angle of the cutter 34 of only one cutter device 27.

In such a case, since the cutter 34 is not inclined about the axis of the cutting edge, the cutting pitch with respect to the roll may change. Therefore, when the tilt angle of the cutter 34 is adjusted by rotating the support shaft 37 by a predetermined amount, the left and right lock handles 66 are loosened in advance, and the handle 52 is rotated and adjusted in an arbitrary direction, and the rear plate 58 is adjusted. By moving the bracket 49 back and forth, the front-rear amount of the cutter 34 can be adjusted to adjust the cutting pitch to a specified value.

Next, replacement of the blade and replacement with a different type of blade only requires the bolt 92 to be loosened.
4, the cutter mounting portion 54 can be removed, and the replacement work can be greatly shortened.
