2.2.4 Calibrating a tangential knife

The purpose of the knife calibration routine is to detect and, if necessary, to correct
problems related to the concentricity of the tangential knife blade.
NOTE: Knife calibration should be done each time the knife is changed and should be
checked if the knife shows signs of wear.
Knife calibration errors may be due to any of the following causes:
•
Origin deviation. The knife tip is slightly rotated in relation to its theoretical 0°
angle. This error can be corrected by adjusting the origin.
•
Lateral deviation. The knife tip deviates from its theoretical center in the lateral
direction. This error can be corrected by adjusting the lateral parameter.
•
Longitudinal misalignment. The knife tip deviates from its theoretical center in
the longitudinal direction. This error can be corrected by adjusting the
longitudinal parameter.
