ESTING THE
AW
1.
Verify the jaws are heated to normal operating tempera-
ture (approximately 260°-320° F).
2.
Trim any film just below the forming tube with scissors so
it does not hand down into the jaw area.
3.
Tape a piece of TIPI paper to the bottom of the forming
tube so the paper hangs into the jaw area.
4.
Disable the registration rollers, pull belts, and the knife
using the operator interface.
5.
Run the machine in empty bags/single cycle mode for one
cycle.
The jaws close on the paper and leave an imprint, showing inadequate
contact areas.

in the procedure depending on the type of drive link; those differences
are identified in the procedure.
