Machine Adjustments; Compression (Nip) Roller Adjustment - Advanced Poly-Packaging T-1000-S14 Advanced Poly-Bagger Operation Manual

4.1 Machine Adjustments

Periodically, the T-1000 will require readjustment or realignment 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, you should 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). Not enough 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.
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 (Fig. 4-14 &
Fig. 4-15).
Compression adjustment is a two step process. First, the upper and lower roller 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 counter-clock wise until the lower roller
is parallel to the upper roller and leaving 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 (TIP): A light source (lamp) positioned to the rear of the T-1000 showing light in the gap of the
rollers will assist in judging whether the upper and lower roller are parallel.
With the rollers slightly touching and parallel, turn each adjustment screw 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 screws 1/2 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 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 re-tighten the two locking bolts on the upper block of the
