•
Cut-off spring tension
. E
nsure that the spring that provides power to cut-off arm has
enough tension to cut through the tape. Replace the spring if it is too weak.
Problem
:
Tape tail does not stick down properly.
The end of the tape on the back side of the case as it leaves the machine has not adhered well to
the case. Check these conditions:
•
Tape tension
. Tension should be is smooth and not too tight. Tape tension ‘snap back’ will
cause tape tail to recoil and not stick well on the back of the case.
•
Tape head roller contact
. Ensure that the wipe-down roller is actively pushing the tape
down and that the spring is in good condition and set to the right tension.
Problem
:
Tape is off-center.
The line of tape is not centered over the gap between flaps on the top or bottom of the
case. Look for the following conditions:
•
Tape roll position
.
Ensure that the tape roll is fully pushed on to the spool.
•
Tape head straightness
.
Ensure that the tape head sits straight in its bracket and is not
tilted to one side.
•
Obstructions
. Look for obstructions that could be pushing the tape off center.
Problem
:
Tape Falls Forward on Bottom Tape Head.
The beginning end of the tape must stand vertically in front of the tape head front roller
in order to contact the leading end of the next case. A bow made across the tape by the
tape head guides helps to stiffen it, and a static electric charge on the tape head rollers
attracts the tape and helps to keep it in place. If the bottom tape will not stand vertically,
look for the following conditions:
•
Contamination
. The tape may be wound around the roller, or there may be dirt on the roller.
•
No static charge
. Dust roller surfaces with talcum powder to the increase static charge on
the roller.
•
Incorrect tape head guide settings
. Ensure that the tape holder or finger is set correctly.
See the Dekka tape head manual.
•
Inappropriate environment
. A strong breeze in the vicinity of the tape sealer can cause the
tape to blow down. High temperature or humidity may affect the tape characteristics.
•
Inappropriate tape
. Some brands and types of tape have more ‘body’ than others, so a
change of tape may be needed, particularly in difficult ambient conditions. We recommend
that the tape have minimum thickness of at least 1.7 mil.
