Setting the Roller Gap
Now that the rollers are properly aligned you are ready to set the gap for the work you are running.
Raise the top roller evenly as described in the previous section and place the substrate between the rollers.
Now lower the top roller evenly until the roller just touches the substrate. Then rotate each knob an additional three quarters of a revolution. This will allow for about 1/16” spring compression when the material is fed thru the laminator. (Rule of thumb is that the roller gap should be about 1/16” less than the thickness of the substrate.)
With the proper gap it will not be possible to pull the board and slide it between the rollers.
Once the gap is set feed a test board through the laminator. If the rollers crush the board, the roller gap is set too close.
