Tension Control Knob
The tension control knobs are located on the right side of the mandrels that hold the laminating film. They
are used to:
A. Control film tension
B. Prevent the film rolls from free spooling.
C. Flatten any film curl
D. Smooth film lay on the rollers
As a rule, the lighter the tension, the better. The mandrel tension may also be used to assist in keeping the
lamination flat. If the laminate curls up when it exits the back rollers, reduce the upper roll tension or
increase the bottom roll tension. If it curls down, reduce the bottom roll tension or increase the upper roll
tension.
Please remember to use the minimum amount of tension necessary to insure a crease free and high
quality lamination.
During single sided laminations use extra attention to assure that there is zero or minimal tension on the
film, as of equal importance is an appropriate film of a high quality and in good condition.
In the event that there is excessive film wrinkling on the rollers that show on the laminate, mandrel tension
may assist in smoothing this out.
Take careful note of the film direction to the mandrel clip orientation
Mandrel Clip
Each 1-ingh mandrel has one mandrel clip and each 3-inch mandrel has two of these clips opposed 180
degrees – use caution so that you do not cut yourself –. These clips are located in the center of each
mandrel they are designed to hold the film to the core of the mandrel when in operation and to aid in film
removal from the mandrel by allowing the core to slip when turned in reverse. Take note when the
laminator is set up whether this clip is holding the mandrel to the film core, or whether it is allowing it to
slip. If it is allowing it to slip, the mandrels may be in the wrong position and should be reversed – see
also installation instructions on these mandrels
