The following are the basic webbing procedures for webbing films without a release liner:
•Select films slightly wider than the image to allow for a border without film waste. A border of 1/8" to 1/4"
•Ensure the main roller’s temperatures are set according to the recommendations of the laminates being used (see literature enclosed in your material box).
WARNING! The rollers should be down and turning while heating up to provide even heat distribution and prevent roller flat spots from developing.
•Once the laminator reaches correct operating tempera- ture, stop the laminator and raise the top roller.
•Load and center the films on top and bottom unwind shafts with the dull adhesive side facing out and the unwind brake tension released.
NOTE: Check if the film widths of the lower and upper web are the same!
•TOP FILM: Pull the film down from the top unwind shaft, behind the top center idler and place it evenly over the face of the top roller.
•BOTTOM FILM: Pull the film up from the bottom unwind shaft, behind the front bottom idler and place it evenly over the top film draped over the face of the top roller.
•The two films will then heat and stick together.
•Set the Shim Wheels to 1/16" (2mm) to allow for the thickness of the

•Feed the
NOTE: For top and bottom film combinations of
10 mil (250 microns) or less, feed over the first idler and under the second. For film combinations of 10 mil or over, feed over both chill idlers.
•Raise the top pull roller and advance the leader board through the pull rollers.
•Holding the leader board up against the top edge of the top pull roller lower the roller. Make sure the rear Shim Wheels are set to 0" (0mm).
•Return to the front of the laminator and set the front Shim Wheels to
•Using the foot switch advance the films, applying light unwind brake tension gradually on both unwind shafts until there are no wrinkles in the film as it goes into the nip.
