Machine Adjustments; Compression (Nip) Roller Adjustment - Advanced Poly-Packaging T-1000 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.
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 aluminum 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, motor, clutch and brake mechanisms.
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. Holding the
brake pulley to stop it from turning, 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 and excessive wear on the clutch.
