Abstract

The present invention relates to a method and to means in sawing, preferably in frame sawing. The method according to the invention is characterized in that the movement of the saw blade is compulsory guided along slides in such a way that the rearward part of the saw blade - seen in the moving direction thereof - is given a movement towards the work piece while the forward part of the blade at the same time is given a movement away from the work piece, at which the ratio between the movement of the saw blade towards respectively from the work piece and the total movement of the sawblade during one sawing cycle is within the range 7:100 - 1:100. The means according to the invention is characterized in at least two pair of slides (3, 4), along which the saw blade (2) is guided during its movement in both sawing directions, the angle between the slides is in the range between 172 DEG and 179 DEG .
