Fig. 128
To do this:
• Trigger the tying process manually with machine at a standstill
• Turn the needle yoke manually on the flywheel in working direction upwards until the
upper needle (8) lifts a little
• Tighten the flywheel brake to lock the needles in this position
• Loosen the screw (9) on the knotter and swing the knotter up
• Loosen nut (10) completely so that there is no tension on the spring (11)
• Rotate the twine bar (12) back and forth manually
Note
The tip of the twine bar (12) must not collide with the upper needle (8). If necessary, move the
twine bar (12) back by loosening screws (3) and (4) so that the twine bar (12) does not collide
with the arms of the upper needle (8).

Checking / setting the dimension “a”
• Loosen the flywheel brake and turn the needle yoke manually on the flywheel in working
position upwards until the needle yoke is in idle position (i.e. the crank arm (1) and needle
connecting rod (2) are in extended position), refer to chapter “Setting the needle yoke
brake”
• Tighten the flywheel brake to lock the tying in this position
• Press the twine bar (1) on the tip manually to the channel slot
The lateral distance “a” between the tip of the twine bar and the channel slot has to be “a” = 5 -
10 mm in this position.
The setting of the lateral distance "a" is made on the control linkage assembly (5) of the twine
bar (1). For setting unscrew counter nuts (6) and screw (7) off the joint bearing. Turn the control
linkage until the dimension is set to “a” = 5 - 10 mm. Then tighten the counter nuts again. The
twine bars must be freely movable in this position.
