SC-5 SURE CUT Servo Knife Cutter

Symptom
◆
Cut is not square.
Possible cause
The blade speed is too
low.
The blade is misaligned.
The cutter bushings are
not properly gapped.
The knife bevel is not
symmetric.
For rigid products the
puller is too close to the
cutter.
Solution
Low blade speeds can cause
excessive blade interruption.
Increase blade speed or
decrease the blade cut path
area.
Check that blade is 90 degrees
relative to the bushing holder.
If the cutter bushings are not
properly gapped, the blade
may be free to move with the
extrudate. Check and adjust if
necessary. See Appendix A.
If the knife bevel is asymmet-
ric, the blade will tend to move
in the direction of the smaller
bevel. Be sure that the bevel is
symmetric. NOTE: You can
use this to your advantage with
some rigid products.
There must be enough space
between the puller and cutter
to allow for extrudate stoppage
that occurs during cutting.
Allow enough space so no cut
shock is detectable at the input
to the belt puller with your fin-
gernail.
