Abstract (en)

[origin: EP2769813A2] The positions of the slitter blades of a slitter-winder are calibrated using a laser to perform measurement and calibration of the fiber web cutting point of each slitter blade pair. Measurement and calibration is preformed on the top slitter blade of each of a multiplicity of slitter blade pairs one after another. The laser measures one slitter blade of each slitter blade pair while they are engaged. The slitter blade pairs between the laser and the slitter blade pair being measured are not engaged. Carriages which support the slitter blades have position sensors which the laser measurements calibrate and the blade pair positions are measured and the carriage positions are read simultaneously. The cutting edges of the slitter blades are sharpened to have straight sides and the laser measurement system is located so the laser beam is directed to the straight side.
