Setting the needle thread tension
Fig. 2: Setting the needle thread tension
Preliminary tension of the needle thread
With an open primary tensioner (2) a small amount of residual
tension of the needle thread is required. The residual tension is
generated by the preliminary tensioner (1).
The preliminary tension also affects the length of the cut needle
thread end (starting thread for the next seam).
To set the preliminary needle thread tension:
1.
Turn the preliminary tensioner (1) clockwise (– direction) for
a shorter starting thread.
2.
Turn the preliminary tensioner (1) counterclockwise
(+ direction) for a longer starting thread.
Primary tension of the needle thread
To set the primary needle thread tension:
1.
Set the primary tension of the needle thread (2) to be as low
as possible.
The thread interlacing should be exactly in the middle of the
material being sewn. With thin sewn material, excessive
thread tension can lead to undesired ruffing and thread bre-
akages.
