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 compression tension assembly. Then re-tighten the nut on the adjustment screws.
Replace the covers, plug the cord into the power outlet and turn the main power on.
4.4 Dancer Assembly Adjustments (Roller Shaft)
A roller shaft, holding in position a roll of bags, will rest on the side-plates of the dancer
assembly. The roller shaft must be parallel to the upper and lower guide rollers to allow proper
tracking through the center of the T-1000. If the roller shaft is not parallel, the web of bags may
track to the left or right.
Note: The roller shaft should not be out of alignment unless damaged or jolted in shipment.
4.5 Dancer Bar & Brake Strap Adjustment
The dancer assembly maintains proper bag web tension throughout the stop / start feed motion of
the T-1000. Web tension is required for proper tracking. If the tension is insufficient, the web
may track left or right. Thinner bags require less tension than thick bags. Web tension is
created by friction of the brake strap along with the weight of the dancer bar pulling downward
on the web of bags. Friction of the brake is created by the weight of the bag roll and the spring
tension on the brake strap. As the dancer bar raises, spring tension is decreased and friction is
decreased. If the web of bags is slack between the dancer roller and nip rollers, there is not
enough tension on the bags. If the web of bags break prematurely, the tension is too high.
To correct the web tension, the dancer bar or brake strap spring must be adjusted (Fig. 4-16).
To increase brake strap tension, relocate the spring on the dancer rail, one hole at a time, closer
to the dancer roller. To decrease tension with the brake strap, move the spring on the dancer bar,
one hole at a time, away from the dancer roller.
The dancer bar pivots on two shoulder bolts which extend from the side-plates. The downward
force can be adjusted by repositioning the pivot point. To increase tension with the pivot
position, move the pivot position away from the dancer roller. To decrease tension, move the
pivot position closer to the dancer roller.
Note: Inspect the dancer bar to ensure that it is parallel to the roller shaft.
4.6 Upper Roller Guides
Two aluminum web guides, are located on the upper rear roll of the T-1000 used for fine
adjustment of tracking. Once the web is tracking within +/- 1/8" left to right, the aluminum web
guides can be used to further assist tracking. Hold the upper roller in place while turning and
sliding the aluminum guides close to the bags without touching the bags.
NOTE: If the bags are not tracking properly, the aluminum 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 as described in section 4.8.
