Symptom
◆
Annular rings
present on the
extrudate.
◆
Burrs at cut site.
Possible cause
The belt puller is too
close to the cutter.
The anti-backlash bear-
ings are not working
properly.
The bushings do not pro-
vide enough support dur-
ing cutting.
The bushing gap is too
wide.
The blade speed is too
low.
The blade is too thick.
Solution
If the extrudate is interrupted
(stopped during processing),
annular rings can develop,
especially on a thin-walled
product. Slightly increase the
distance between the puller and
the cutter, and test the product
until the distance is correct.
Stop the puller and try to move
the lower belt by hand. The
lower belt should not be able to
travel backwards when you try
to move it. If it does, the anti-
backlash bearings must be
replaced. Contact Conair
Service.
Change bushing design to make
more supportive.
Check that bushing gap is
0.001-0.003 in. larger than
blade. Adjust if necessary.
Increase blade speed or
decrease the cut path area.
Use a thinner blade or add heat
to extrudate.
