Teflon Adjustment
A Teflon sheet that prevents the bag from sticking to heater bar surfaces is located immediately behind
the front plate. The Teflon should periodically be inspected for wear or damage. If holes or tears exist, the
Teflon rolls can be turned (rotated) to cover the contact surfaces with fresh Teflon.
If an adjustment of Teflon is required, turn the main power OFF and unplug the power cord. Lower the
inner frame by pulling the handle downward. The Teflon rollers are located on the outside lower frame,
on the left and right side of the inner frame that extends beneath the side plates. See Figure 4-3.
To adjust the Teflon, turn the lower roller counter-clockwise approximately ¼ of a turn using a flathead
screwdriver. If there is too much tension on the Teflon, turn the roller counter-clockwise, releasing ALL
of the tension on the Teflon. If there is too much slack in the Teflon, turn the top clockwise.
CAUTION: If Teflon tension is not released, the Teflon will tear when the seal bar engages.
Teflon Replacement
Once the Teflon Sheet has reached the end of the roll, it is time for it to be replaced. To order a
replacement Teflon Sheet, call APPI Service and refer to part number TP-300500, T-1000 Teflon Sheet.
1. Turn the power to the OFF position and unplug the power cord. Let machine cool for at least an
hour.
2. Remove the Lexan guard by unscrewing the two acorn nuts connected to the shafts. Remove the
four Button head screws that hold the Front Plate to the inner frame. Set these aside in a safe
place.
Note: Fiber spacers located behind the front plate may fall when removing the Front Plate screws.
3. Slide the Front Plate back and remove Teflon Guide. Determine if your machine is a Standard
Frame or a Drop Frame. Look closely at the Teflon Sheet Bracket. If you have a Standard Frame
the LONG side of the Teflon Sheet Bracket goes up. If you have a Drop Frame the SHORT side
goes up. This is important for reassembly.
4. Remove the two springs and clean the adhesive from both shafts. See Section 5.10c for Exploded
Diagram.
5. Separate the two shafts.
6. Lay one Shaft on the top of the Teflon Sheet and measure from the edge of the Teflon Sheet to
the edge of the Shaft. Ensure the Teflon Sheet is in the center of the Shaft.
7. Wrap a piece of tape on the Shaft at the edge of the Teflon.
8. Take the second Shaft, lay the first Shaft next to it and wrap tape around the end of the second
Shaft in exactly the same place as the first. Keep the taped ends on the same side of the Teflon
Sheet.
9. Remove the adhesive backing from one end of the Teflon Sheet.
10. Align one Shaft parallel to the Teflon Sheet with the taped end of the Shaft meeting up with the
edge of the Teflon Sheet. Once the shaft is in position, lower onto adhesive side of the Teflon
Sheet.
11. Roll the Shaft until you reach the end of the adhesive part.
12. Repeat with the other Shaft, ensuring the taped ends are on the same side. Once the Teflon Sheet
has been rolled over the Shafts, the tape may be removed.
13. Determine if your machine is a Standard Frame or a Drop Frame. Look closely at the Teflon
Sheet Bracket. If you have a Standard Frame the LONG side of the Teflon Sheet Bracket goes up.
If you have a Drop Frame the SHORT side goes up.
14. Lay the Teflon Sheet Bracket in the middle of the Teflon Sheet.
15. Place the Shaft into the cutouts of the Bracket then pull the spring so that you have two wraps
between the Bracket and the Shaft. Be sure the Spring is in the groove on the Shaft.
16. Repeat the same procedure on the other Shaft.
17. Wind the Teflon so that the supply is at the TOP of the Teflon Sheet Bracket. Standard Frame,
LONG side up; Drop Frame, SHORT side up (refer to step 13)
18. Place Teflon Sheet Bracket Assembly back into the bagger. If your machine is a Standard Frame,
ensure the LONG side is up, and for a Drop Frame the SHORT side is up.
