The end of the tape on the back side of the case as it leaves the machine has not adhered well to the box.
Check these conditions:
•
Tape tension
. Tension should be is smooth and not too tight. “Snap back” will cause tape tail to
recoil and not stick well on the back of the case.
•
Tape head roller contact
. Tape head contact or wipe-down rollers should make good contact with
the box. Adjust roller spring tension, if necessary.
Problem
:
Tape is off-center.
The line of tape is not centered over the gap between flaps on the top or bottom of the box. Look for the
following conditions:
•
Tape roll position
. Check that the tape roll is fully pushed on to spool.
•
Tape head straight
. Check that the tape head sits straight in its bracket and is not tilted to either
side.
•
Obstructions
. Look for obstructions that could be pushing the tape off center.
Problem
:
Tape Falls Forward on Bottom 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 help to stiffen it and a static
electric charge on the tape head rollers attract the tape and help to keep it in place. If the bottom tape will not stand
vertically, examine the following factors:
•
Contamination
. Tape may be wound around the roller or other dirt on the roller.
•
No static charge
. Dust roller surfaces with talcum powder to the increase static charge on the roller.
•
Tape head guides
. Check that the tape holder or finger is set correctly, see tape head manual.
•
Ambient conditions
. A strong breeze in the vicinity of the tape sealer can cause the tape to blow
down. High temperature or humidity may affect tape characteristics.
•
Type of tape
. Some brands and types of tape have more ‘body’ than others and a change of tape may
be needed, particularly in difficult ambient conditions.
