<p>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 ( 11 A, 12 A) 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 ).</p> |
