Further, the rotary cutter steel 10 is arranged so that the axis of its shaft 11 is approximately parallel to the axes of the shafts 2 and 3 of the drive endless body 1, and so as to face the downward running path X-x. be. The support rotating roller 15 is arranged close to the upper part of the rotary cutter steel 10 so that the axis of its shaft 16 is approximately parallel to the axis of the shaft 11 of the rotary cutter steel 10.
The cutter 12 and the cutter 12 are arranged in such a position that the log A can be placed so that its longitudinal direction coincides with the axes of these. The rotary knife steel 10 is fixed to the movable base 18 via a bracket 17 that supports the shaft 11, and the supporting rotary roller 15 is fixed to the movable base 18 via a support rod 19 and a bracket 20.
8 respectively. The movable table 18 includes a roller 21 and an actuation mechanism 22 consisting of a reversible motor or the like that rotates the roller 21. By the operation of the actuator mechanism 22, the movable table 18 reciprocates, and integrally drives the rotary cutter steel 10 and the support rotary roller 15. The endless body 1 is moved back and forth with respect to the regulating surface Y of the downward running path x-X.

削に備える。The implementation procedure is as follows: rotary cutter steel 10 and support rotary roller 15
When the log A on the log conveyor 24 is stopped at the standby position shown by the solid line in FIG.
It is placed on the rotary cutter rt410 and the supporting rotary roller 15 so that its longitudinal direction substantially coincides with their axes, and when the placement is completed, the movable table 18 is moved in the direction of the drive endless body 1. The log A is the downward running path x of the driving endless body 1
- When approaching or reaching the regulating surface Y of x (the position indicated by the dotted line in Fig. 1), the detector 23 detects the log A, and in response to that signal, the endless belt 6 starts running, and the rotary blade steel 10 starts rotating. do. Running of endless belt 6 and friction member 7 attached to its surface
A strong rotation is applied to the log A by contact with the surface of the log A, and the cutter 13 of the rotary cutter steel 10 performs cutting. The cut pieces B fall onto the carry-out conveyor 26 via the guide plate 25 and are carried out of the machine. In addition, the rotary knife steel 10 and the supporting rotary roller 1 when rotationally driven
It is desirable that the rotation direction of the log 5 is set to be in the forward direction of the rotation direction of the log A applied by the driving endless body 1 as in the embodiment. As the cutting progresses, the log A becomes smaller in diameter, but in this case, the log A is placed on the regulating surface Y of the driving endless body 1.
The movable table 18 is continuously or intermittently advanced so that it can be continuously supported by the rotary cutter steel 10 and the supporting rotary rollers 15. When moving the movable table 18 continuously, the movable table 18 is
tj- When moving the moving table 18 slowly forward and moving the moving table 18 intermittently, for example, when the detector 23 detects the log A, the moving table 18 is temporarily stopped, and the log A is reduced in diameter by cutting and then moved again. This is done by configuring the movable table 18 to move forward when the detector 23 detects the log A. In this way, when the movable table 18 reaches a point I where the log A can no longer be supported by the All 1M action Y of the driving endless body 1 (the position indicated by the dashed line in FIG. When the moving table 18 is detected, the moving table 18 is stopped and the cutting of one log A is completed. When the cutting is completed, for example, the detector 30 operates the cutting II mechanism 27 to separate the support rotary roller 15 from the rotary blade 1io, and the control 2
8 is discharged from the machine via the guide member 29 by free fall, and the movable table 18 retreats to the ItJ machine position to prepare for cutting the next log A.

をはかり得る等の諸効果を有する。In this invention, the raw wood is rotated while being supported at three locations: the regulating surface of the drive endless body, the rotary cutter barrel, and the support rotating roller, and the cutter attached to the rotary cutter barrel is used to cut the raw wood. Since the cutting is done and the friction member is attached to the surface of the endless band of the drive endless body, it is possible to give a strong rotation to the log, and since the cutting is performed while rotating the log, the circumferential surface of the log is uniform. The circular shape is maintained during cutting, and the longitudinal direction of the raw wood is approximately aligned with the axis of the rotary knife barrel, resulting in relatively long, good-quality chips with approximately uniform thickness and length. This contributes to the production of particle boards with high utility value, and since the structure uses a long driving endless body as a member to support the raw wood, it can always respond to the reduction in the diameter of the raw wood. By supporting the raw wood at three locations, centerless cutting is possible, and the raw wood can be cut to an extremely small diameter, resulting in a significant improvement in yield.
