Functional description of twine motion indicators for upper twine
For „double knotter“ version

BP000-069
The upper twine path can optically be monitored by the movement of the twine motion indicators
(1) (reflectors). The twine motion indicators (1) are located on the top of the machine. While the
bale is being formed, the twine motion indicators (1) should move back and forth in a pulsing
cycle. In normal operation, the twine motion indicators (1) raise and lower simultaneously. In the
event of a malfunction, the defective twine motion indicator (1) of the twine path is not in the
same position as the other twine motion indicators (1).
Possible malfunctions when the twine motion indicators (1) remain at the top:
•
Twine has wrapped around the billhook.
•
The knotter needle has missed the upper twine strand (twine is not cut).
•
The knot has been left hanging on the billhook (after tying is completed one twine indicator
(1) stays down longer than the other ones).
Possible malfunctions when the twine motion indicators (1) remains at the bottom:
•
The twine tension is too low.
•
The upper twine strand is torn.
•
The billhook has not tied a knot.
