Roller Gap Adjustment - Gfp 455 TH Operating Manual

18. Roller Gap Adjustment

Check for uneven roller gap
• Place a sheet of paper between the rollers the full width of the laminator
• Turn the pressure-adjusting hand-wheel to lower the upper rubber roller
• Apply some pressure so the two rollers just touch
• Check to see if the space in between the rubber rollers is even across the machine
If the space is not even:
1. Open the left and the right cabinet covers;
2. Check whether the left and right pressure-adjusting brackets are loose.
If loose, tighten brackets and then replace cabinet covers
3. Check whether the longitudinal taper gears on the two sides are loose.
If they are loose, take apart the left transverse taper
gear and then remove the screws of pressure-adjusting brackets, then tilt
the longitudinal taper gear, and tighten the screws on the top of the gear
4. Remove the left transverse taper gear, turn the longitudinal taper gear until the
space of the two sides of rubber rollers becomes even.
5. Tighten the screws of each component and replace the side covers
