<p>The invention relates to a method for calibrating the position of blades of a slitter-winder of a paper or board machine, which blades (11,12) are attache d to blade carriages (11A,12A) or the like disposed on guides (14,13) or the like, in which method the position of the blades (11,12) of the slitter-wind er is measured by means of a multipoint measurement method, whereby the positio n of the blade carriage (11A,12A) of the respective blade (11,12) is measured. In the method the position of the blades (11,12) is calibrated with a calibration tool (20). A positioning member (21) of the calibration tool (20 ) is arranged to touch a slitting edge (17) of the blade (11) to be calibrated . The position of the calibration tool (20) is measured by means of the multipoint measurement method and the position of the slitting edge (17) of the blade (11) is determined based on the measurement result of the position of the calibration tool (20). The invention also relates to a device for calibrating the position of blades of a slitter-winder of a paper or board machine, which device is disposed in connection with the slitter-winder of t he paper or board machine, which slitter-winder comprises pairs of blades comprising a top blade (12) and a bottom blade (11), attached to their respective blade carriages(1IA,12A) arranged to be movable along a guide (14,13) or the like, in connection of which slitter-winder means (15,16,18,1 9) are arranged for measuring the position of the blades (11, 12). In the metho d the device used for calibrating the position of the blades (11,12) is a calibration tool (20) which is arranged to be attached to the same guide (14 ) with the blade (11) to be calibrated. The calibration tool (20) comprises a means (21) for indicating the slitting edge (17) of the blade (11) and means (23,16) for measuring the position of the calibration tool (20).</p> |
