ABSTRACT:
A positioning member (21) of a calibration tool (20) touches a slitting edge (17) of one of the blades (11, 12) to be calibrated of a slitter-winder of a paper or board machine. The tool (20) position is measured by the multipoint measurement method and edge position is determined based on the measurement result of the position of the calibration tool (20). A device for calibrating blade position is disposed in connection with the slitter-winder which comprises a top blade (12) and a bottom blade (11), attached to respective blade carriages (11A,12A) which are movable along a guide (14,13). The calibration tool (20) is arranged to be attached to the same guide (14) with the blade (11) to be calibrated. The calibration tool (20) has 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).
