9.9.2 Tape is not Cut Uniformly
The tape is not cut properly every time. In the worst situations, several cases may be taped
together.
Check the following conditions:
•
Tape head position.
If the tape head is set too high, the cut-off knife will not be fully
activated, resulting in poor cut-off. The tape head side plates should be within 1/16” and
1/8” of the case. Verify also that cases ride fully down between the conveyor belts to
provide proper contact with the tape head cut-off knife.
•
Knife extension.
Be sure that the knife extends enough to fully contact the tape during
the cutting stroke.
•
Tape tension.
Unroll tension should be smooth and not too tight, as a ‘snap back’
caused by stretched tape can cause a jagged cut-off, and tape pieces may stick to the
blade.
•
Clean knife.
Clean the blade and apply a little silicon or oil to avoid adhesive build-up on
the sharp points.
•
Knife blade wear or damage.
Blades must be very sharp to work well. The points are
easily damaged if contacted by any hard material. Replace the blade if it seems dull.
•
Cut-off spring tension.
Verify that the spring that provides power to the cut-off arm has
enough tension to cut through the tape. Replace the spring if it is too weak.
9.9.3 Tape Tail does not Stick Down Properly
The end of the tape on the rear side of the case as it leaves the machine has not adhered well to
the case.
Check for the following conditions:
•
Tape tension.
Tension should be smooth and not too tight. ‘Snap-back’ will cause tape
tail to recoil and to adhere poorly on the rear of the case.
•
Tape head roller contact.
Tape head contact or wipe-down rollers should make good
contact with the case. Adjust roller spring tension if necessary.
CAUTION!
The tape head knife is very sharp!
