12.7.1 Setting the twine tension on the upper twine strand (double knotter)
Fig. 171
The upper strands of twine (1) should be held by the brakes (2) up to a tensile force of 100 -
120 N.
Before the twine brakes will allow the twine to slip through, the twine tension arm (3) should
move downward against the spring force until the twine (1) is guided through the eye of the
tension arm (4) almost without moving to the side.
Testing the twine tension:
• Tie the cord (1) onto a spring balance The spring balance has to indicate 100 - 120 N
shortly before the cord slips through.
You can increase the tension by turning the wing nut (5) tighter. To reduce the tension, loosen
the wing nut.
The dimension "X" is based on the tying twine selected and must be determined in each
individual case by testing in the twine strand. A pretension of the twine strand that is too high
may cause knotter errors and place too heavy a load on the components involved.
Pre-setting X = 65 mm
