<p>Circular saw blades are treated in a straightening machine for eliminating unevennesses in the saw blades. The machine is provided with rollers for straightening uneven sections of the saw blade (1). The straightening rollers are sets of balls (22, 22', 23, 23') which are pressed from both sides against the blade while a relative movement between the blade and the balls takes place. This movement may either be circular or along radial tracks of the blade. Alternatively, disc-shaped rollers are arranged with their axes perpendicular to a radius of the saw blade, and are running along radial tracks according to a relative movement between the saw blade and the rollers. <IMAGE></p> |
