Gathering Brush Tension Adjustment
The tension of the gathering brushes can be varied by
using the adjustment knob and tension gauge provided
on the top of the brush assembly. This knob limits the
amount of mesh between the upper and lower brushes.
The amount of mesh between the brushes depends upon
the application. On bread bags, the brushes are usually
adjusted to give a gentle pull on the bag neck as the bag
passes through the brushes. This takes slack out of the
bag and pulls the bag neck straight to properly enter the
tyer belts. On bun bags, it is usually not desired to pull on
the bag with the brushes. Rather, the objective is merely
to feed the bag neck smoothly into the tyer belts. In this
case, the gathering brushes should have very little or no
mesh. In all cases, the brush mesh must be limited so that
the bag neck tension does not tend to pull the product
through the guides and into the brushes.
Machine performance will determine the proper value the tension will be set at. Record this value in the
space below each time the roller tension is recalibrated.
