MAINTENANCE AND SERVICE
PROBLEM
: Film gets wrapped around the laminating rollers while hot
laminating.
SOLUTION:
The film is threaded improperly. If the adhesive side face to the
roller, the film will be wrapped around the rollers. Thread the film in proper
position.
The laminating temperature is too high, the film will be melted and wrapped
around the roller. Decrease the laminating temperature.
Set the RUN / STOP switch to STOP immediately, set the HOT / COLD switch
to COLD. After the roller cool down, cut the film on the top and bottom, just in
front of the stabilizer bars Reverse the roller at a very low speed and allow the
machine to back out the film that is wrapped around the rolls, pull the film off
the roller.
PROBLEM:
Wrinkling of the plastic on a laminated material.
SOLUTION:
Check the tension of the film, make sure the film is threaded
properly (see film threading).
PROBLEM:
Film is not properly adhered.
SOLUTION:
The laminating temperature is too low, there is not enough
heat for melting the adhesive. Increase the laminating temperature.
PROBLEM:
The laminated material seems to have a irregular surface that
does not match the texture of the paper being coated.
SOLUTION:
This is usually caused by adhesive build-up or dirt on the
rubber rollers. Inspect the rubber rollers and clean it.
Damages to the rubbers can also cause irregularities in the surface of the
film.
PROBLEM:
General haziness or cloudiness in the film after lamination.
SOLUTION:
Increase the temperature or decrease the speed. That
cloudiness is a function of incomplete adhesion. On a variable speed
machine loaded with thicker film, it may be that the film is being run too
fast.
