PROBLEM
Film Breakage Issues
Film Breaks Inside The
Carriage (Usually Between The
Rubber Stretch Rollers)
Film Is Breaking Between The
Last Aluminum Roller And The
Load
Table 4-1. Troubleshooting Chart (Continued)
POSSIBLE CAUSE
Rubber rollers are damaged
Film tension is set too high.
Zero or Gain settings for the hall
effect (Film Feed Trigger) are
incorrect.
Tension spring is too heavy for
the application.
Film roll sets too low in relation
to the feed rollers.
Sharp edges are cutting the film

SOLUTION
Carefully review the rubber rollers for
cuts or nicks. Any raised spots can dam-
age the film and propagate a tear.
Raised spots can be carefully shaved or
sanded smooth but if the surface showing
craters or holes so that the surface is not
level, then the roller needs to be replaced.
Film runs through the carriage properly
and there are no sharp corners on the load,
but the film still breaks.
Lower the film tension value at the touch-
screen.
Observe the feedback value of the hall
effect located on the touchscreen.
Re-set the ZERO and GAIN values
according to the film feed setup instruc-
tions in the manual. ZERO setting should
be a value of at least ten above the hall
effect feedback value to operate properly.
Film carriage appears to be calibrated cor-
rectly and film appears to be correct. Film
still breaks or damages a light load with
the film tension set at values below 10%.
Replace the standard tension spring with
the light duty tension spring (supplied
with the machine).
Look for film traveling under the bottom
edge of the trailing rubber roller.
Adjust the bottom film mandrel to allow
the bottom edge of the film to run cor-
rectly on the trailing rubber roller.
Observe the load. See if the film break
starts at any one sharp edge.
Options are:
1. Correct the load if possible.
2. Reduce the film tension at the touch-
screen.
3. Change film type used.
4. Reduce the prestretch ratio.
