The Art of Lamination
Basic Rules
Do not attempt to laminate abrasive or metal objects
such as staples, paper clips and glitter, as they may
damage the heat or pull rollers.
Do not force items into the nip area of the heat rollers.
An item that is not easily drawn into the laminator by
the heat rollers is probably too thick to laminate.
Wrinkles may result if an attempt is made to reposi-
tion an item once it has been grasped by the heat
rollers.
Do not stop the laminator before an item has completely
exited the pull rollers. Even a momentary stop will
cause a mark (heat line) on the laminated item.
Good, consistent lamination is a result of combining proper
heat, tension and dwell time. Dwell time is controlled by
the speed of the motor and is defined as the amount of
time the material to be laminated is compressed between
the heat rollers.
As a general rule, thicker items and film need to run at slower
speeds because they extract more heat from the rollers at
a quicker rate. Setting the speed control at slower settings
gives the laminator longer dwell time thus allowing proper
lamination of thick items. Thinner items, such as standard
copier paper (20 lb. bond) and tissue paper, extract less
heat from the rollers and can be run at faster speeds.

Film Tension
Proper film tension, known as brake tension, is the minimum
amount required to eliminate wrinkles in the finished item.
The film should be taut. A properly adjusted roll of film
should not require excessive force to turn by hand.
Film tension should be enough to introduce a minor amount
of drag as the film unrolls. Insufficient tension causes wrin-
kles, while too much tension causes stretching (necking).
Uneven tension between the top and bottom rolls creates
curl. Too much upper tension creates upward curl while
too much bottom tension causes downward curl.
The heat roller clutch is set at the factory. Periodic adjust-
ments may be necessary if after adjusting unwind and rewind
brake tensions do not improve your output quality.
