Abstract: Equipment for stabilizing rotation of a blade in a circle saw and for staying at the wanted sawing line which equipment comprises the formation devices (1,2); (7,8); (10,11) of a magnetic field in connection with a ferrous metallic circle saw blade (3) and equipment for adjusting the intensity of the mentioned magnetic field, such as a sensor (14) that measures the sideway position of a control center (13) and a circular blade (3). Of the formation devices of the magnetic field metallic parts (1); (7) or (10) that direct at least magnetic flux in the last resort to the circle saw blade (3) or part of them are located in relation to the circle saw blade (3) outside its toothing (4), at the location of the teeth essentially to the level of the circle saw blade (3).

Abstract: Stabilization device of the blade (1),(14) of a saw device with the help of which device the lateral movements which occur during the sawing of the blade (1) of a band sawing machine of a circular saw blade (14) at least at the location of the wood (9) to be sawed can be reduced. The equipment comprises at least magnetic devices (6, 7);(12) which are adjusted to be at a distance from each other and are located at the other side of the blade (1),(14) with the help of which magnetic devices one can form a magnetic flux (10) which runs through the area which is apt to the lateral movements of the blade (1),(14) between the mentioned magnetic devices.

Abstract: Arrangement in order to tension a counter element (1), such as a blade of a sawing device, such as a blade (15) of a band sawing machine in combination with a roll or a slide block to a chosen sawing line with the help of the mentioned counter element and in order to direct the counter element to make it stay at the mentioned line. The arrangement comprises a magnetic device (14) in order to improve the functioning belonging to the counter element (1) and in order to improve the sawing result with the help of which magnetic force created by the magnetic device the blade (15) is being controlled with a force which has the same direction which force pushes the blade (15) against the counter element (1).

Abstract: A method to strain a sawing device blade (1) made of magnetic material to a chosen sawing line and to steer it to stay on said line. By means of elements (6), a sawing tightness is strained to blade (1) in moving said blade sidewise to the chosen sawing line, the said sawing line is formed in a sawing portion between said elements (6), and by means of said elements (6), blade (1) is continuously effected during sawing in order to adjust the portion intended for the sawing line of blade (1) to stay on the said sawing line.
