Abstract

A method and an arrangement for sawing a log 11 in a blade saw unit 10. The log 11 is fed through the blade saw unit 10 by means of feed devices 12, 13, 14, 15. The log 11 is sawn by one or more parallel blade saw bits 30, capable of moving laterally from its centre on a shaft 31. Each bit 30 is supported from its outer circumference by a bit guide device 20, which is fixed to the frame of the saw unit 10 essentially on a level with the shaft 31 of the bit 30. The solution is characterised in that the axis of rotation P of the bit 30 is aligned from the lower surface 11a of the log 11 towards the upper surface 11b of the log 11, when it is normally aligned from the upper surface 11b of the log 11 towards the lower surface 11a of the log 11. The additional friction caused by the sawdust clogged in the bit guide device and the overheating of the bit 30 are thus eliminated. <IMAGE>
