てそれが落下しないように挟持する。Next, the sawing process is performed with a circular saw 12.12 as shown in Figure 3(a).
To explain the case where the left and right are paired, sawing machines 8, 8
The circular saw 12.12 is moved forward and backward by the walking motor 14 and the walking shaft 15, and is set on the traveling frame 3, and the ruler plate 20 is placed on the front side as shown in FIG. The object on the opposite side is rotated downward and into the working position. The deflection cylinder 27 and the lock cylinder 26 are set so that the angle is widened, and when the traveling frame 3 is moved from the right side to the left side as a forward stroke in this shape, the circular saws 12, 12 cut on both sides of the log. The product is sawn on the front side and escapes from the sawn groove on the other side, but as mentioned above, it is swung slightly away from the sawn surface of the product, so return marks are formed on the sawn surface. Also, the plate surface of the circular saw does not come into pressure contact with the sawn surface and create resistance. In addition, the left ruler plate 20.2 is placed in the groove.
0 enters and guides, and when the sawing is completed, a large drum material is obtained. At this time, the press rollers 41 are pressed against the back plate and held therein to prevent it from falling.

As shown in FIG. 4(a)-(b), set the drum material on the traveling frame 3 with the end cut at 90 degrees so that the sawn surface is horizontal, and the near side as shown in FIG. 4(b). ruler board 2o
... is rotated downward to take the working position, and the ruler plate 2 on the opposite side is
0 is raised to take a retreat position, the circular saw 12.12 is turned horizontally in the opposite direction, and the right side is deviated so that it is slightly wider than the left side, and then the traveling frame 3 is set on the fourth return stroke.
When sawing by running to the right in the figure, both sides become back plates and the center part becomes a pillar material.

るから復行程に移行する時、木回しを行なう。At that time, if the thickness of the log is larger than the width of the pillar material and the planks can be removed from both sides, saw the wood to a width equivalent to the thickness of the plank in the forward stroke, and then turn the drum material into a wood. With the circular saw 12. With the circular saw set in place, move forward so that the distance between the circular saws 12 becomes narrower and perform the sawing process in the backward stroke.You will get boards from both sides, and the center part will be the same width as the pillar material, so it will be 90 degrees on the front side. If the wood is finished and then sawed back and forth, two boards and a square piece of wood will be obtained, and even in this sawing process, there will be no turning marks. However, if two circular saws 12, 13 are attached to the main shafts 11, 11 on both sides, as shown by the solid line and the chain line in Fig. 8, the backboard and planks can be obtained from both sides of the log in one stroke. When transitioning to the go-around stage, perform a wood turn.

ことができる。In addition, if the diameter of the log is large enough compared to the dimensions of the pillar material and one side can be made into a board that is relatively thick and can be sold at a high price, the log can be moved to one side and set on the traveling frame 3. At the same time, if you take a wider step and saw it, one side will become a regular backboard and the other side will become a thick backboard, so this thick backboard will be sawed with a saw machine with the equivalent of a roller table. If sawing is performed in such a way that the core of the log deviates from the center of the sawn product, the wood will often bend, so in this case, when transitioning to the backward stroke, move the circular saw 12.12 a little closer to the material. If you step forward and saw in this way, you can perform a corrective sawing called so-called lick sawing in the backward stroke. At this time as well, by swinging the circular saw so that the sawing side of the product is slightly separated from the sawn surface of the product, it is possible to prevent the product from being scratched and the formation of marks.
なお、丸鋸１２．１３がアッパーカットになる側には木
材の上面を押える昇降ロールを設けることが望ましい。In addition, it is desirable to provide an elevating roll that presses the upper surface of the wood on the side where the circular saws 12 and 13 make upper cuts.
