Assembling the neat seam beginning (NSB)
Additional Instructions M-TYPE DELTA - 00.0 - 05/2020 5
2 Assembling the neat seam beginning (NSB)
When the needle exits the sewing material after the first stitch, the thread-
pulling knife pulls the initial thread into the clamp. This ensures
secure sewing.
Following the 2nd stitch, the remaining thread is cut off and removed by
the suction device.
Important
The NSB will not be active until the completion of the 2nd stitch after the
machine was switched on.
The NSB is not active if the needle tip remains below the throat plate level
during sewing.
2.1 Presettings outside of the machine (optional)
The kit has been preset at the factory and does usually NOT have to be
adjusted.
Do not check or adjust the presettings outside of the machine UNLESS
the NSB is without function.
Order
1. Complete the presettings outside of the machine.
2. Check/adjust the cutting pressure (p. 7).
3. Check/adjust the clamping spring pressure (p. 8).
4. Assemble the NSB (p. 9).
5. Activate the NSB (p. 15).
Fig. 1: Presettings outside of the machine (1)
To complete the presettings outside of the machine:
1. Remove the clamping spring (1).
2. Loosen the nut (2).
3. Extend cylinder (4).

2.2 Checking and adjusting the cutting pressure
Order
1. Complete the presettings outside of the machine (p. 5).
2. Check/adjust the cutting pressure.
3. Check/adjust the clamping spring pressure (p. 8).
4. Assemble the NSB (p. 9).
5. Activate the NSB (p. 15).
Fig. 4: Checking and adjusting the cutting pressure
Proper setting
Screw (1) is adjusted such that the thread-pulling knife (2) moves smooth-
ly and the counter blade (3) cuts the loose thread cleanly.
To check and adjust the cutting pressure:
1. Screw in screw (1) in such a way that the screw head abuts on
the counter blade (3).
NOTICE
Property damage may occur!
Risk of knife breakage if pressure is adjusted too high.
Do not adjust the cutting pressure too high.

• Increase the cutting pressure: Turn screw (1) clockwise
• Reduce the cutting pressure: Turn screw (1) counterclockwise
3. Carry out a cutting test.
4. Readjust the cutting pressure if necessary.
2.3 Checking and adjusting the clamping spring pressure
The clamping spring clamps the needle thread after the 1st short stitch
and prior to cutting.
Order
