Abstract:
In a method for dressing a saw blade, including an endless belt-saw blade (B), wherein the saw blade (B) is routed above a table (3) in a movement direction, wherein after measuring an unevenness of the saw blade (B) then the saw blade (B) is guided along a roller unit (6) which is adjustably led perpendicular to the movement direction and parallel to a plane in which the saw blade (B) runs, wherein each of two roller pairs (24, 26; 25, 27) has an upper roller (26, 27) arranged vertically over a lower roller (24, 25) and one pair of the two roller pairs smooths according to a measured unevennesses, and wherein for each of the two roller pairs (24, 26; 25, 27) a portion of the lower roller (24, 25) is fixed and the upper roller (26,27) is movably guided, an improvement comprising: moving the two upper rollers (26, 27) directly proportional to a signal corresponding to the measured unevennesses which is a deviation from an ideal plane (I) of the saw blade (B), and in regions of the saw blade (B) without the unevenness the upper roller (26, 27) and the lower roller (24, 25) of each of the roller pairs (24, 26; 25,27) simultaneously bearing on the saw blade (B).
