640t – Installation and Operating Instructions

Testing the Web

After webbing the machine, it is important that the films run straight and evenly.

To test the web:

1.Set the roller pressure handle to an appropriate position.

2.Press RUN or the foot switch and run approximately 6 in. (10 cm) of laminate.

3.Press STOP or release the foot switch.

4.Visually inspect the top and bottom films where they enter the nip.

The films should be tight against the rollers at both ends. If they are not, use the tension adjustment knobs to tighten the loose supply film brake and run another test.

5.Ensure that the release liner take-up is keeping the liner tight against the idler bar.

Use the upper film supply tension knob to properly tension the release liner.

6.Run test materials before laminating good materials.

Clearing a Film Jam (Wrap-up)

Film jams (wrap-ups) may occur if the film is loaded backwards or if the area at which film exits the equipment is blocked. The film, when jammed, wraps around the rollers. Jams also occur if something is too large to pass through the rollers.

Determine the best course of action to clear the jam. It may be necessary to rotate the rollers in the reverse direction. Set the speed to min. Press and hold REVERSE on the control panel.

CAUTION: Be careful to not cut the pressure rollers when cutting the film. Failure to observe this notice can result in damage to the rollers.

To clear a jam:

1.Immediately press STOP to stop the machine.

2.Remove the print clamp and feed tray.

3.Do one of the following.

a.Pull one of the webs while running the laminator in reverse.

b.Cut the film near the rollers, set the pressure adjustment to 1/2”, and pull the film out the back of the machine.

c.Cut the film near the rollers, set the pressure adjustment to 1/2”, grasp the loose ends of the web, and pull straight out the front of the machine.

4.Replace the feed tray and print clamp. See “Removing and Installing the Feed Table” on page 6-3 and “Removing and Installing the Print Clamp” on page 6-3.

5.Re-load the film if necessary. See “Loading Film” on page 6-2.
