The twine brakes (1) can be found in the twine boxes. The twine brakes (1) hold taut the upper
twines from the twine box to the upper twine brakes or the lower twines from the twine box to
the lower twine brakes.
The drawing tension of the twine brake should only be set so high that the upper or lower twines
are taut but still can be pulled easily.
Different types of twine may have different friction properties. Therefore, the drawing tension of
the twine strand must be checked when changing the type of twine.
