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 attached 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-winder is measured by means of a multipoint measurement method, whereby the position 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 the 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 (15,16,18,19) are arranged for measuring the position of the blades (11, 12). In the method 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).
L'invention concerne un procédé de calibrage de la position de lames d'une unité refendeuse-enrouleuse d'une machine à papier ou carton, lesdites lames (11, 12) étant attachées à des supports de lames (11A, 12A) ou similaires disposés sur des guides. Selon ledit procédé, la position des lames (11, 12) de l'unité refendeuse-enrouleuse est mesurée au moyen d'un procédé de mesure multipoint, la position du support de lames (11A, 12A) de la lame respective (11, 12) étant mesurée ; la position des lames (11, 12) étant calibrée au moyen d'un outil de calibrage, un élément de positionnement (21) dudit outil (20) est disposé de manière à toucher une arête de refendage (17) de la lame (11) devant être calibrée ; et, la position de l'outil de calibrage (20) est mesurée au moyen d'un procédé de mesure multipoint, et la position de l'arête de refendage (17) de la lame (11) est déterminée sur la base du résultat de mesure de la position de l'outil de calibrage (20). L'invention concerne également un dispositif de calibrage de la position de lames d'une unité refendeuse-enrouleuse d'une machine à papier ou carton, connecté à l'unité refendeuse-enrouleuse comportant une lame supérieure (12) et une lame inférieure (11) respectivement attachées à leur support de lames (11A, 12A) pouvant coulisser le long d'un guide (14, 13) ou similaire, des éléments (15, 16, 18, 19) connectés audit guide servant à mesurer la position des lames (11, 12). Selon l'invention, le dispositif de calibrage de la position des lames (11, 12) est un outil de calibrage (20) conçu pour être attaché au même guide (14) que la lame (11) devant être calibrée. L'outil de calibrage (20) comporte un élément (21) destiné à indiquer l'arête de refendage (17) de la lame (11) et des éléments (23, 16) destinés à mesurer la position de l'outil de calibrage (20).
