If it is found that the laminating rollers have flat spots on it due to the rollers not being gapped, simply gap
the rollers and allow the laminator to go through several heating and cooling cycles then run the laminator
without film until the flat spots disappear. The silicones that we use in our rollers are of an extremely high
grade and hold nearly no memory for extended periods. We have never had one roller returned because
the rollers did not recover from not being gapped. This issue is typically just a nuisance to the operator.
Idler bars
There are two idler bars on a stand model laminator and three idler bars on a table top model, one for the
upper laminate and one or two for the lower laminate. These idler bars help direct the film over the rollers
to provide a more consistent heat transfer and a high quality lamination.
Top idler
It is necessary for the laminating film to wrap around this idler for proper lamination. By using the idler
rollers on the machine, you increase the time that the rollers heat up the film, which results in a better
lamination
Bottom Front Idler
This idler is included on laminators that were shipped for table top models only it is necessary on
machines which have the film mounted on the machine so that the film is guided away from the heated
roller and around the sliding idler
Sliding Idler Bar
The sliding idler bar is a 1" roller located below the lower heated (front) roller. While the machine is cool,
please take a few moments to "practice" raising and lowering it.
Its purpose is to allow the operator to thread the laminating film without burning their fingers.
To raise the roller place your hands under each end of the roller and gently and evenly raise the roller as
high as it will go, about 3 inches, and pull it slightly toward you. It will automatically lock in place. To
lower it, place your hands under each end of the roller, push it away from you and slightly up then gently
lower each end evenly. Do not force the idler if it becomes jammed--gently straighten it out.
