PROBLEM
:
No power is getting to the laminator.
SOLUTION
: Make sure there is power at the electrical outlet being used, and
make sure both ends of the power cord are firmly engaged. There are fuses inside
the laminator, but dead outlets and loose power cord connections are the most
common causes of this problem.
PROBLEM:
Wavy or rippled sections in the laminate, especially toward the
center of the web.
SOLUTION:
These “heat wrinkles” are caused by excess temperature and/or
speed for the film being used. Slightly speed up the motor and/or use a lower
temperature appropriate for that particular film.
PROBLEM: General haziness or cloudiness in the film after lamination.
SOLUTION:
Increase the temperature. 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 and is not getting enough time on the heat rollers.
PROBLEM:
Bubbles in the center of the web and/or film not sticking to the
center of an item.
SOLUTION:
This problem can be caused by excessive laminating roll pressure.
Putting too much pressure on the laminating rollers actually decreases pressure in
the center of the web.
The other likely cause of this symptom is worn rollers. For example, if hundreds of
thousands of 18-inch / 46cm wide sheets are laminated on a 27-inch machine, the
center of the rollers can get worn down more than the ends of the rollers. In this
situation, the laminating rollers should be replaced.
