Paper pull tension ( Wave 2 & 4 )
Cause:
These patterns are caused by too little ( Wave 2 ) or too much ( Wave 4 ) tension of the
laminated material between the laminating rollers and the pull rollers.
laminated material between the laminating rollers and the pull rollers.
Solution:
To remove these waves, adjust the paper pull adjustment and/or laminating roller pressure.
Brake tension ( Wave 5 )
Cause:
These are straight bands across the image, usually at uneven intervals and are usually minimal
to excessive. This intermittent tension is caused by binding of the film core on the brake or
core end inserts.
to excessive. This intermittent tension is caused by binding of the film core on the brake or
core end inserts.
Solution:
Ream out the core.
Cooling / brake tension ( Wave 6 )
Cause:
These waves may have no particular pattern and may manifest themselves in a wavy ( rather
than flat ) finished product. They are caused by stresses or unevenness in the laminate or the
image.
than flat ) finished product. They are caused by stresses or unevenness in the laminate or the
image.
Solution:
To prevent this type of waving, reduce the tension on the film. If this proves to be ineffective,
check for gauging ( uneven thickness across the width ) in the laminate.

Wrinkles on both edges after the pressure roller ( Wave 7 )
Cause:
Excessive film tension may be applied to the roll of film.
Solution:
To prevent this type of waving, check the film tension as film rides around the chrome roller.
Minimum film tesion should be achieved. Adjusting the spreader roller may also assist with
this type of wave form.

Wrinkles from center to edge after pressure roller ( Wave 8 )
Cause:
Pressure roller air pressure may be to great or moisture in the paper may contribute to this
type of wrinkle.
