SAWING MACHINE - SAGMASKIN

The present invention relates to a sawing machine with one or more log splitting saw blades followed by one or more splitting knives.

Today, saw blades are known for fastenings in which the guides, saw blades and splitting knives are fixedly attached to the saw machine. The problem with such solutions is that the distance between the fixed control points working the wood when viewed in the sawing direction of the log increases to such an extent that curved sawing is no longer possible. Thus, the saw blade or blades do not follow the cutting of the wood but saw the logs in the line in which they are fixedly mounted. This substantially impairs the utilization ratio of the wood.

The object of the invention is to eliminate the above-mentioned drawback and to provide a new type of sawing machine. The sawing machine according to the invention is characterized in that both the saw blades and the splitting knives are located in a separate sawing unit articulated to the saw machine body and following the log loop. The articulation of the sawing unit enables curved sawing even when sawing logs of large diameters, because thanks to the articulated attachment, the distance between the fixed control points in the sawing direction is short enough and the saw blades and splitting knife can better follow wood cutting.

The invention will now be described by way of example with reference to the accompanying drawing, in which

Fig. 1 shows a side view of the log between the saw blades and the guides.

Fig. 2 shows the same as Fig. 1 with another sawing unit according to an embodiment.

From the feed direction, the saw machine has flexible drive wheels 1, a self-centering guide rail 2, carving blades 3,4 rotating about a horizontal axis and a vertical axis, saw rollers 5 and a saw unit 6. The saw blades 7 and splitting knives 8 are located in a saw unit 6 articulated to the saw machine frame 9 and thus follows the logging of the log.

In the embodiment shown in Fig. 2, the sawing unit comprises guide rollers 10 in front of the saw blades 7. These guide rollers guide the sawing unit B according to the circumference of the wood 11. The sawing unit 6 is articulated to the body 9 of the sawing machine about a horizontal axis 12 and can additionally be articulated about a vertical axis 13 shown in Fig. 2 by a dotted line.

Due to the possibility of movement provided by the articulation of the sawing unit 6, the curved sawing of the log is also possible with a large saw blade located on a circular saw blade 7.

It will be apparent to those skilled in the art that various embodiments of the invention may vary within the scope of the claims set forth below. Thus, the number of saw blades 7 and splitting knives 8 may vary from one to several. Depending on the straightness or curvature of the log to be sawn, the saw blade 7 and the splitting knife 8 may be in the same line or also in a different line with the lines of the carving blades 3,4 carving the sides of the log when sawing according to the examples.
