16.3 Setting the thread-pulling knife
Fig. 66: Setting the thread-pulling knife
Proper setting
When the thread-pulling knife (1) is at rest, the distance between the high-
est point of the control cam (7) and the roller (5) is 0.1 mm.
The control cam (7) makes contact with the clamping ring (6).
The marking (3) on the thread-pulling knife (1) is adjacent to the cutting
edge of the counter blade (2).
The knife carrier (4) has no axial play, but can still run smoothly.
To set the thread-pulling knife:
1. Loosen all 4 screws on the clamping ring (6) and push the clamping
ring (6) toward the hook bearing.
2. Tighten all 4 screws on the clamping ring (6).
3. Loosen both threaded pins on the control cam (7).
4. Turn the lever (8) as far as it will go against the screw (10).
5. Set the distance between the roller (5) and the highest point of the
control cam (7) to 0.1 mm.
6. Tighten both threaded pins on the control cam (7).
7. Loosen the clamping screw (9) on the lever (8).
8. Turn the thread-pulling knife (1) until the marking (3) on the cutting
edge of the counter blade (2) is adjacent to it.
9. Tighten the clamping screw (9). Take care to ensure that there is no
axial play.
