Model 4200 Series Laminator Manual
Film Alignment Procedure

Fig. 21

Fig. 22

The film supply shafts of the 4200 come with pre-drilled holes on the right side, (Figure 21). The 4200 is drilled for 9" (21 cm) and 12" (31 cm) film widths. Loosen the locking screw on the right side retaining collar and move to the corresponding hole to match the width of your roll of film. Tighten the locking screw in the pre-drilled hole.

Proper film tension, known as brake tension, is the minimum amount required to eliminate wrinkles in the finished item. The film tension is set at the factory. Tension adjustments are not necessary if you are using 1.5 or 3 mil THINK & TINKER, LTD. film unless the lamination is curling up or down. Generally, 5 and 10 mil film require more tension; and, as the film roll becomes smaller, tension increases, requiring more adjustments. Film tension should be checked occasionally to assure that the adjustment is correct.The film should be taut. A properly adjusted roll of film should not require excessive force to turn by hand. Film tension should be enough to introduce a miner amount of drag as the film unrolls. Insufficient tension causes wrinkles, while too much tension causes stretching (necking). Uneven tension between the top and bottom rolls creates curl. Too much upper tension creates upward curl. Too much tension on the bottom causes downward curl.

  1. The machine is equipped with external tension knobs located on the left side, (Figure 22). Turning the knobs clockwise increases the tension while counterclockwise decrease the tension.
  2. Laminate some test samples to check for proper tension. Further adjust if necessary.
