Pre-setting: Dimension X = 30–35 mm
„ In order to increase or reduce the drawing tension, the dimension X must be increased or
reduced via wing nut (2).
For „double knotter“ version
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.

16.17 Checking/setting twine tension on upper twine
BP000-193
The twine tension depends on the selected twine and must be checked. A twine tension that is
set too high may cause knotter errors and place too heavy load on the parts involved. The
upper twines (3) should be held by the twine brakes (4) up to a tensile force of
100–120 N .
Before the twine brakes will allow the upper twines to slip through, the twine tension arms (1)
should move downward against the spring force until the upper twines (3) are guided through
the eyes of the tension arms (2) almost without moving to the side. The twine tension is set via
dimension X.
Factory setting dimension X=65 mm
Checking the twine tension
„
Tie the upper twine (3) onto a spring balance.
„ Pull the upper twine (3) and read the tensile force shown on the spring balance.
Æ
If the tensile force is 100–120 N just before the upper twine slips through, the setting is
correct.
Æ If the tensile force is >120 N just before the upper twine slips through, the tensioning force
of the spring must be reduced (increase dimension X).
Æ
If the tensile force is <100 N just before the upper twine slips through, the tensioning force
of the spring must be increased (reduce dimension X).
