Step 2: Compression Adjustment
With the rollers slightly touching and parallel, turn each adjustment coupler approximately 1/2 turn
clockwise. Then test the compression by putting a bag between the rollers. Attempt to pull the bag
between the rollers. If the bag pulls out easily, turn the compression adjustment coupler another 1/2 turn
clockwise. Continue this adjustment until the bag is slightly difficult to pull out of the rollers. Turning
the coupler equally on both sides keeps the rollers parallel. Raise and lower the upper roller assembly to
ensure that it latches properly without having requiring pressure.
Caution: Over-tightening of the compression adjustment screws may cause damage to the rubber roller
or the motor.
When you are satisfied with the compression, slightly raise the upper roller assembly, and slowly lower it
until it almost touches the upper roller. If the gap is consistent across the width of the rollers and it
appears parallel, lock the inner frame upward and re-tighten the two locking bolts that hold the coupler in
position.
Step 3: Stop Bolt Adjustment
If the compression is sufficient when lowering the upper roller assembly, but then the compression is lost
due to over extending, the latch mechanism, the stop screws must be adjusted. Loosen the locking nuts
that hold the stop bolts into position. Then, turn the stop bolts 1/2 turn each. Then lower the roller
assembly and check the compression when the coupler is against the stop bolts.
When in the rollers and latch mechanism has been properly adjusted, the upper latch assembly will lower
and lock into position when the latch handle is pressed all the way downward. Additionally, the
compression will be sufficient for the bag to separate, but not too tight to cause the motor to stall or
"chatter".
4.4 Idler roller Guides
Two plastic web guides, are located on the rear idler roller. These guides are used for
fine
adjustment of
tracking. Once the web is tracking /- 1/8" left to right, the plastic web guides can be used to
further assist tracking. Hold the upper roller in place while turning and sliding the plastic guides close to
the bags without touching the bags.
NOTE: If the bags are not tracking properly, the plastic guides could cause the bag web to turn or fold
over. If this occurs, slide the guides further away from the web and make adjustments to correct tracking
issues.
4.5 Heater Bar Adjustment
The pressure bar, when actuated by the seal cylinder, is forced against the front gripper plate. The
pressure must be great enough to grip the bag so that the bag does not move when the rollers reverse. If
the bag slips through the pressure bar and gripper plate, the bag may not be separated or the bag not
sealed properly.
Check for free movement of the spring-loaded gripper plate: The power off and the when the heat has
dissipated from the heater bar, press inward on the front gripper plate with sufficient force to move the
gripper plate inward on both sides. Then, press in on one side only, one side at a time, and ensure that the
gripper plate springs back outward when released.
If the gripper plate does not spring back, adjustments are required.
With power turned off air removed, remove four screws holding the face / gripper plate to the front plate.
Pull the assembly out carefully as not to disconnect or damage wiring. Disconnect the thermocouple wire
at the connector and the heater connectors and pull out the assembly.
