Roller Pressure Adjustment; Roller Gap Adjustment - Gfp 865DH Operating Manual

21. Roller Pressure Adjustment

• When the pressure-adjusting hand-wheel is turned clockwise, the top rubber
roller comes down and the pressure will increase
• With a counter-clock turn, the top rubber roller goes up and the pressure will decrease.
• Too much nip pressure will wrinkle the output. Bring the nip roller down to just touch the film,
then increase slightly
• NOTE: The Gfp 847DH model requires less nip pressure than the 865DH. When using the 47",
bring the rollers down only to touch the film together. Do not over tighten the nip pressure.

22. Roller Gap Adjustment

1. To 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
2. If the space is not even
Open the left and the right cabinet covers;
•
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
11. Remove the left transverse taper gear, turn the longitudinal taper gear until the space of
the two sides of rubber rollers becomes even.
12. Tighten the screws of each component and replace the side covers
