11.5 Fabric deflector
Fig. 41: Fabric deflector
Proper setting
The distance between carrier roller (2) and fabric deflector (1) must be
as small as possible.
To keep the sewing material from entering into the slot, the distance must
be adjusted in line with the wear of the carrier roller (2).
Information
For machines without a thread trimmer, the fabric deflector (1) can also
be used as a thread-pulling knife for the thread chain.
11.6 Toothed belt tension
Proper setting
The toothed belt is tensioned enough to ensure an exact transmission of
the carrier roller step lengths.
Disturbance
If too great, the toothed belt tension can result in excessive wear and
malfunctions.
