Dancer Assembly Adjustments (Roller Shaft); Dancer Bar And Brake Strap Adjustment; Upper Roller Guides - Advanced Poly-Packaging Advanced Poly-Bagger T-1000-S18H Operation Manual

4.3 Dancer Assembly Adjustments (Roller Shaft)

Dancer Assembly
Please refer to 5.6 when using these instructions. 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-S14. 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.
If the rollers are not parallel, loosen two Socket Head Bolts on Dancer Frame and move Dancer Frame
backward or forward until the Dancer Roller is parallel with Guide Rollers on the T-1000. When Guide
rollers are parallel with Dancer Rollers, tighten the bolts on the Dancer Frame.

4.4 Dancer Bar and Brake Strap Adjustment

The dancer assembly maintains proper bag web tension throughout the stop/start feed motion. 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 the 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 rises,
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 breaks prematurely, the tension
is too high.
To correct the web tension, the dancer bar or brake strap spring must be adjusted. To increase brake strap
tension, relocate the spring on the dancer rail by sliding the block closer to the dancer roller. To decrease
tension with the brake strap, move the spring on the dancer bar and slide the block back away from the
dancer roller.
The dancer bar pivots on two shoulder bolts that 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: For the brake strap to function correctly, the roll shaft must be installed so the strap wraps
around the roll shaft. Inspect the dancer bar to ensure that it is parallel to the roller shaft.

4.5 Upper Roller Guides

Two plastic web guides are located on the upper rear roll of the T-1000-S14 and are used for fine
adjustment of tracking. Once the web is tracking within +/- 1/8" (0.31 cm) left to right, the plastic web
guides can be used to further assist with 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.
Note: If bags have an air relief hole or hanger hole, shift the bag to the right or left of center to avoid
having the hole pass directly under the perforation sensor.
Note: Use the web guides for minor adjustments only. Major adjustment of the guides requires
relocation of the bag roll on the bag roll shaft.
