Abstract

A method and an apparatus for sawing a piece of timber and particularly for edging a board. The piece of timber is brought to pass in its longitudinal direction through a measuring station and further, maintaining its position, to a sawing machine. The optimum width and sawing direction are determined by the measuring data obtained by means of measuring gates collected in the memory of a computer. The computer controls the sawing blades. The blades of the sawing machine are turned to take the desired sawing direction and are moved at an even speed in lateral direction during the sawing process. The apparatus comprises a conveyor for transferring the log of timber, a plurality of gates for measuring the optimum width and direction, a computer for collecting the data. The computer controls the blades so that during sawing, the sawing lines coincide with the edge lines of the calculated optimum board. The sawing machine is mounted on vibration dampers which act as springs. The dampers are mounted in the corners of the sawing machine in such positions that the stiff direction of the damper is directed towards the required turning point and the flexible direction coincides with the periphery of circles having radius R.sub.1 and R.sub.2 drawn around the pivot axis.
