19. Roller Gap Adjustment

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.

1. If the space is not even:

a. Open the left and the right cabinet covers.

b. Check whether the left and right pressure-adjusting brackets are loose.

2. If loose, tighten brackets and then replace cabinet covers.

a. Check whether the longitudinal taper gears on the two sides are loose.

b. 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.

3. Remove the left transverse taper gear, turn the longitudinal taper gear until the space of the two

side.

of rubber rollers becomes even.

4. Tighten the screws of each component and replace the side covers.

 A friction clutch is installed on the drive side of the rear lower pull roller shaft inside the left

cabinet. Adjusting the compression nut will increase or decrease the rear pull roller speed to

regulate film tension between the nip and the pull rollers.

 Adjust the compression nut by using the locking wrench supplied with the machine. Rotating

the nut clockwise will increase speed of the pull rollers and so the film tension between the nip

and pull rollers; a clockwise rotation will decrease the pull roller speed and so the film tension.
