17.2 Setting the thread-pulling knife
Proper setting
When the thread-pulling knife (1) is at rest, the distance between the
highest 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) must have no axial play, but still run smoothly
