The tip of the thread seperator 6 must insert itself between the
underthread 2 and the gimp 1.
For this both threads must be taut. For the gimp this is achieved
through a torque rod on the hook block. Thin and smooth gimps may
have to be threaded through 3 holes on the unwinding arm of the yarn
stand.
During the movement of the needle plate and thread catcher 8 with
thread seperator 6 the hook thread glides into the slit 5 of the needle
plate.
Through this the hook thread is securely guided to the lower clamp 9
and the gimp to the upper clamp 4.
The hook thread must jump out of the slit 5 when the thread seperator
6 is about 5 to 7 mm in front of the cutting edge of the fixed knife 3.
Through the residual movement of the thread catchers 8 both threads
are pulled into the clamps 4 and 9 before cutting.
