Replacing The Moving Knife - JUKI DDL-9000 Engineer's Manual

○ When the sharpness is insufficient although the blade
face is enough sharpened, it is because the left and
right blade faces of moving knife and counter knife
do not simulataneously come in contact with each
other. At this time, adjust the inclination of the counter
knife.
(Reference) To improve the contact of the blades
of moving knife and counter knife, it is
effective to change the angle of the
arrow mark shown in Fig. 24.
When the side of D in Fig. 23 is hard to
cut, decrease this angle, and when the
side of C is hard to cut, increase the
angle.
