4.5.3 Machines with a neat seam beginning
The clean seam beginning kit provides a short and neatly sewn
needle thread at the seam beginning.
After the 1st stitch the needle thread is clamped by the thread
clamp (11) and pulled back by the thread retractor (13) so that the
needle thread only protrudes by a small amount at the seam
beginning.
The exact setting is described in the Additional Instructions.
Fig. 12: Machines with a neat seam beginning
To thread the needle thread on a machine with neat seam
beginning:
1. Insert the needle thread in a wavelike manner through the
3 holes of the thread guide (1): From top to bottom through
the left hole, then from bottom to top through the middle hole
and, finally, from top to bottom through the right hole.
