Blade holder

The alignment of the blade holder and its distance from the roll affect the doctoring result.
If the holder is aligned wrong, the blade wears into a wedge shape.
If the distance of the holder from the roll is wrong, the loading pressure on the blade is not correct, either. This may cause a pass through.
Impurities in the rivet tunnel of the blade holder may cause variation in the loading effect. In this case, the holder must be cleaned and realigned and the distance to the roll adjusted.
The angle of the holder must be adjusted in strict accordance with the instructions.
