Machine Adjustments; Tracking And Alignment Adjustments; Compression (Nip) Roller Adjustment - Advanced Poly-Packaging Advanced Poly-Bagger T-1000-S14 Operation Manuals

4.1 Machine Adjustments

Periodically, the T-1000-S14 will require readjustments or realignments of components to ensure proper
operation. Adjustments may be required after transportation, excessive handling or due to normal wear
and tear.
CAUTION: Machine adjustments, electrical troubleshooting and component replacement should
be performed by qualified maintenance technicians familiar with safety practices including, but not
limited to, equipment lock-out / tag-out, voltages and pneumatics. If you are not familiar with the
equipment or have not received training on the T-1000-S14, consult with APPI Technical Support
before attempting adjustments or repairs.

4.2 Tracking and Alignment Adjustments

To avoid spillage of product in an automatic loading operation and loss of production in a manual loading
operation, make machine adjustments to correct the tracking and alignment of the web of bags.

4.3 Compression (Nip) Roller Adjustment

The drive roll compression is the force that exists between the two feed rolls (rubber-covered grooved roll
and grooved steel roll). Too little drive roll compression will prevent the bags from tearing off after each
sealing operation. Too much drive roll compression will cause extra wear on the drive roll and the motor.
NOTE: Always clean rollers before adjusting.
Turn the power switch to the OFF position and unplug the power cord. Remove the left and right side
covers. The compression adjustment is located on the lower outside right and left side plates. See Figures
4-1 and 4-2.
Compression adjustment is a two step process. First, the upper and lower rollers are adjusted to make the
lower roller parallel to the upper roller. Then, the lower roller is adjusted (raised) for proper compression.
On both the left panel and right panel, loosen the two locking bolts on the upper block of the compression
tension assembly. Loosen the nut on the adjustment screw. With the inner frame locked in the UP
position, lower the lower roller by turning the adjustment screws counterclockwise until the lower roller is
parallel to the upper roller, leaving a 1/16" gap between the rollers. Turn the adjustment screw clockwise
alternatively, keeping the lower roller parallel with the upper roller until the rollers come in contact across
the width of the rollers. Slightly lower the inner frame and raise again to ensure that when raised again,
the rollers touch simultaneously. Then "snug" the upper block bolts and recheck the alignment.
NOTE: A light source (lamp) positioned to the rear of the T-1000-S14 showing light in the gap of the
rollers will assist in judging whether the upper and lower roller are parallel.
With the rollers parallel and slightly touching, turn each adjustment screw approximately ½ 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 screws ½ turn clockwise.
Continue this adjustment until the bag is slightly difficult to pull out of the rollers.
CAUTION: Over-tightening of the compression adjustment screws may cause damage to the upper
(rubber) roller or the motor.
When you are satisfied with the compression, slightly lower the inner frame and then slowly raise 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 retighten the two locking bolts on the upper block of the
compression tension assembly. Then retighten the nut on the adjustment screws. Replace the covers, plug
the cord into the power outlet, and turn the main power on.
