Gathering Brush Air Adjustments
The gathering brush comes standard with an
air regulator. The air blows the bag tail down
prior to the gathering brush gathering the bag
tail tight against the brush. The amount of air
can be adjusted by turning the knob on the
regulator to increase or decrease the air flow.
Gathering Belts Speed Adjustment
In normal operation, this switch enables the operator to adjust the
speed of the gathering belts. The belt speed can be adjusted from a
setting of zero to fifteen. In normal operation, each speed setting is
approximately 15 percent faster than the previous setting (see table
below for approximate values). A proper speed setting should pull the
product 1”-2” ahead of the flight and finish tying as the flight catches up
with the product (see pg.58 on how to adjust the belt speed).
In most installations, the belts will not normally run when the conveyor
is stopped. For testing, you may make the belts run with the conveyor
stopped by turning the selector switch on the operator panel to the “ON”
position. Be sure to return the switch to the “AUTO” position after
testing. To properly set the speed of the gathering belts, you must be
running product at normal speed. The speed of the belts should be
adjusted so that the end of the bag is pulled slightly forward from the
flights. As soon as the tyer completes its tie of the package, the
conveyor flight should be just catching up with the package. The flight
then carries the tied package away from the tyer.
The belts should not be run any faster than necessary to ensure that the tie is completed
just before the flight pushes the tied package out of the tyer. If the belts are running too
fast, a bag may be pulled into the tying position before the previous package has been
removed by its flight. This can cause two packages to be tied together or excess wear on
the belts.

If the belts are running too slowly, the package will tend to drag back
against its flight as it is being tied. In addition, it will appear as if the
tyer is not keeping up with the needed production rate.
