GBC 640T Threading Film with a Threading Card, To load films onto the supply shafts

640t – Installation and Operating Instructions

To load films onto the supply shafts:

1.If the supply shaft is on the machine, grasp the bearing end and lift it out of the cradle. Then pull the left end out of the brake hub.

This applies to the top and bottom supply shafts.

2.Slide the new roll on to the shaft and core adaptors, referring to “Fig. 6-3. Poly-in and Poly-out Films.” on page 6-2 to determine how the film unwinds from the roll. Use the set screws in the core adaptors to move the adaptors if needed.

3.Insert the hex end of the shaft into its brake hub and then insert the bearing end in its cradle. See “Fig. 6-7. Supply Shafts.” and “Fig. 6-8. Supply Shaft Cradle End.”

4.Center each supply roll on the shafts by doing the following. Also see “Film Alignment” on page 6-10.

a.Use a ruler to measure from the left edge of the roll to the left side frame.

b.Do the same on the right side.

c.Shift the roll side to side so that both measurements are equal. It is important that the edges of the films are aligned so that adhesive does not stick to the rollers.

5.Center the take-up core on its shaft.

Threading Film with a

Threading Card

The following procedure uses a film threading card that is sometimes provided with new rolls of film. If one is not provided, a scrap of cardboard or poster board with a straight edge is suitable. Either can be reused. Prior to loading film, remove the print clamp and feed table.

Note: These instructions are for loading laminating and mounting films for decaling. The top supply shaft is used for laminating films and the bottom supply shaft is used for mounting film or Kraft paper. If you are not applying mounting film to a laminate, Kraft paper should be used on the bottom supply shaft to prevent adhesive from sticking to the rollers. For more information about loading films for other processes, refer to the appropriate section in this chapter.

To web (load films) the machine:

1.Remove the print clamp and feed tray. Refer to “Removing and Installing the Print Clamp” on page 6-3and “Removing and Installing the Feed Table” on page 6-3.

2.Pull the top film down, thread it under the idler bar, and pull the film back up to the take-up core.

3.Lightly tape both corners of the film to the take-up core. Ensure that the film is pulled evenly and that no bulges exist at either end of the idler bar.

4.Using a very sharp utility knife, lightly score the laminating film approximately 4 in (10 cm) above the upper pressure roller. Be careful to not cut through the release liner.

5.Pull the laminating film away from the liner and drape it over the front of the pressure rollers so that it extends to a little past the bottom of the top pressure roller.
