Film Breakage Issues
Film Breaks Inside The
Carriage (Usually Between The
Rubber Stretch Rollers)

Table 4-1. Troubleshooting Chart (Continued)
POSSIBLE CAUSE
Film is wound incorrectly.
Film core is damaged or incor-
rectly sized.
Film roll sets too low in relation
to the feed rollers.
Film mandrel drag or resistance is
not allowing the film to unwind
properly.
Film carriage aluminum "pres-
sure" rollers are mis-aligned with
the rubber rollers. Film is slipping
across the rollers.
Aluminum pressure rollers are
damaged.
SOLUTION
Film may be wound incorrectly from the
manufacturer. Look for heavy, raised
stripes along the feed axis of the film. This
is known as "gauge banding".
Replace improper film with film in good
condition.
The film core should fit the machine's film
mandrels. Cores that are too small or dam-
aged can cause the film to not rest in the
correct position.
Replace improper film with film in good
condition.
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.
Look for excessive wear under the bottom
mandrel.
Lubricate the bottom and center of the
mandrel. Replace worn parts.
With the film removed from the carriage,
look for an inconsistent gap between the
aluminum and rubber rollers-top and bot-
tom on both sides of the rubber rollers.
Using the socket head cap screws, re-align
the aluminum rollers to the rubber rollers.
Set the gap between the aluminum and
rubber rollers so that there is only a slight
rotational resistance between the rollers.
Carefully review the aluminum rollers for
cuts or nicks. Any raised spots can dam-
age the film and propagate a tear.
Polish the affected areas with a fine abra-
sive until the protrusions are leveled or
replace with a new part.
