4.5.2 Setting the lifting gap (special hook bearing for safety belts)

Fig. 32: Setting the lifting gap (special hook bearing for safety belts) (1)
(1) - Point
Proper setting
The needle thread slides through the passage (2) unobstructed between
bobbin case lifter and bobbin case.
At the moment when the bobbin case lifter is at the point (1), there must
be still be a gap between the nose of the bobbin case and the middle sec-
tion holder.
Information
The lifting gap on the special hook bearing used for belts is markedly wider
than the gap on the standard hook bearing.
If the hook thread under the seam is too loose when using short stitch
lengths, you need to widen the passage between bobbin case lifter and
bobbin case.
