Ptfe Adjustment; Ptfe Replacement - Advanced Poly-Packaging Advanced Poly-Bagger T-1000-S18H Operation Manual

4.6 PTFE Adjustment

A non-stick PTFE sheet that prevents the bag from sticking to heater bar surfaces is located immediately
behind the front plate. The PTFE should periodically be inspected for wear or damage. If holes or tears
exist, the rolls can be turned (rotated) to cover the contact surfaces with fresh material.
If an adjustment of PTFE is required, turn the main power OFF and unplug the power cord. Lower the
inner frame by pulling the handle downward. The 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 material, turn the lower roller counter-clockwise approximately ¼ of a turn using a flathead
screwdriver. If there is too much tension on the sheet, turn the roller counter-clockwise, releasing all of
the tension on the sheet. If there is too much slack in the sheet, turn the top clockwise.
CAUTION: If sheet tension is not released, the material will tear when the seal bar engages.

4.7 PTFE Replacement

Once the PTFE Sheet has reached the end of the roll, it is time for it to be replaced. To order a
replacement sheet, call APPI Service and refer to part number TP-300500.
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 PTFE Guide. Determine if your machine is a Standard
Frame or a Drop Frame. Look closely at the PTFE Sheet Bracket. If you have a Standard Frame
the LONG side of the PTFE 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 PTFE Sheet and measure from the edge of the sheet to the edge of
the Shaft. Ensure the sheet is in the center of the Shaft.
7. Wrap a piece of tape on the Shaft at the edge of the material.
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 PTFE
Sheet.
9. Remove the adhesive backing from one end of the PTFE Sheet.
10. Align one Shaft parallel to the PTFE Sheet with the taped end of the Shaft meeting up with the
edge of the PTFE Sheet. Once the shaft is in position, lower onto adhesive side of the PTFE
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 PTFE 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 PTFE Sheet
Bracket. If you have a Standard Frame the LONG side of the PTFE Sheet Bracket goes up. If you
have a Drop Frame the SHORT side goes up.
14. Lay the PTFE Sheet Bracket in the middle of the PTFE 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 PTFE so that the supply is at the TOP of the PTFE Sheet Bracket. Standard Frame,
LONG side up; Drop Frame, SHORT side up (refer to step 13)
18. Place PTFE 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.
