Classes 252 and 352
With the above machine classes (double blind stitch), the cloth is inserted folded in an
"S" shape (see Fig. 4). In this case, the distance from the seam to the hem edges can
be any value required.
All other essential information on inserting the cloth is described on page 16.
For accurate adjustment of the stitch depths of both plungers/rib shafts, it is
particularly important to follow the correct sequence:
Setting the cloth guide
Depending on the cloth thickness, the cloth guide ļ
at the front of the stitch plate
must be adjusted such that the folded hem edge is positioned exactly between the two
plungers/rib shafts.
Reason: the setting of the right-hand plunger/rib shaft is influenced as a result.
If the hem edge is too far to the left, it will be pierced too deeply by the needle.
If, on the other hand, it is too far to the right, it will not be caught by the needle.
Two folders and edge guides are provided to make it easier to guide the cloth.
-26: the fabric hem is automatically folded into an "S" shape. Seam inset from the
edge of the hem can be any value.
-28: the hem edge is automatically folded into an "S" shape. Seam inset from the edge
of the hem is approx. 5 mm.
