However, according to the prior art disclosed in the above publication, the wood is vertically moved slightly on the sawing orbit individually in the horizontal direction, and the twin band saw is used as a guide for centering the wood vertical sawing line. Since the first vertical grinding line was centered, the log material etc. was ground once to make a drum material, then this drum material was rotated 90 ° and the second centering was performed. Then, the product timber is obtained by cutting the wood for the second time.

Therefore, in this conventional technique, after the first vertical sawing line is centered before the first vertical sawing operation of the wood, the first vertical sawing of the wood is performed to perform the drum material. Make and then return this drum material to the place before the first vertical grinding.

After that, by removing the chuck from the drum material and dropping it on the dolly, the orientation of the wood changes by 90 °, and the second vertical sawing line is centered again and then chucked to perform the second vertical sawing. Is.

Therefore, since wood must be re-chucked in the middle of each of the first and second vertical sawing operations, there is a problem that workability is significantly poor.

In order to eliminate the above-mentioned problems, the present invention performs horizontal and vertical two-direction centering on each of the original and end wood mouth faces and preset-holds these two-direction centering positions. The purpose of the present invention is to make it possible to grind timber from log material etc. all at once by feeding the wood by chucking set on the sawing orbit and feeding it.
