4.7 Teflon Adjustment

A Teflon sheet which 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 a change of Teflon
is required, turn the main power to the OFF position 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 which extends beneath the side-plates (Fig. 4-17). To adjust the Teflon, turn
the lower roller clockwise approximately 1/4 turn using a flathead screwdriver. When fresh Teflon is in
place, turn the roller counterclockwise releasing ALL of the tension on the Teflon.
CAUTION: If Teflon tension is not released, the Teflon will tear when the seal bar engages.

4.8 Teflon Replacement

Turn the power to the OFF position and unplug the power cord. Remove the four screws which hold the
front plate to the inner frame. Pull the front plate from the inner frame and slide the front plate along the
guide rods away from the seal assembly. Then slide the Teflon rollers and the roller holder away from the
heater bar as a unit. Remove and discard the Teflon. Replace the Teflon and rollers with the new Teflon
wrapped on the upper roller. Place the Teflon rollers on the roller holder, ensuring springs are seated in the
grooves on the rollers. Replace the Teflon rollers and holder as an assembly (with the unexpended Teflon
on the upper roller). Replace the front plate and tighten the four screws. Adjust the Teflon as described in
the previous section.
Note: Fiber spacers are located behind the front gripper plate which may fall when removing the front
plate screws.

4.9 Pressure Bar Adjustment

The pressure bar, when actuated by the seal cylinder, is forced against the front plate. The pressure bar
must be parallel to front plate to avoid excessive wear of components.
Turn the power to the OFF position and unplug the power cord. Remove the air line from the regulator and
remove the top cover. Once the air is removed, the pressure bar can freely be pushed toward the front
plate. As the pressure bar approaches the front plate, you can see whether the pressure bar is parallel to the
front plate. If it is not, remember which side of the pressure bar touches first; along with the distance of
the gap on the opposite side. To make the pressure bar parallel to the front plate, the rear channel which
holds the guide rods, must be adjusted. Loosen the nuts inside the channel. On the side opposite of the
"touching" side, turn the nut, located on back side of the channel, clockwise the same distance the pressure
bar was out of alignment. Tighten the inner-channel nuts and test the pressure bar again by sliding it in and
out a few time. Ensure it is parallel to the front plate by slowly pushing it against the front plate. Readjust
the nuts on the rear channel as required.
Note: Pressure bar adjustment should only be necessary after rod or bushing replacement.
4.10 Sealer Cylinder Adjustment
Two "speed controls" operate the speed of the cylinder in and out motion that brings the pressure bar
against the front plate (gripper plate). Increasing the speed of the pressure will increase production. But, if
the pressure bar moves in or out too fast causing the pressure bar to "bang", excessive wear will occur.
The valve which controls the pressure bar cylinder is located on the main center cylinder on the inner
frame (Fig. 4-19). The adjustment knob (B) controls the speed of the pressure bar INWARD (towards the
front plate). The adjustment knob (A) controls the speed of the pressure bar OUTWARD (away from the
