- Tapes: between "3" and "4"
- Elastics: "4"
6. Adjust the presser adjusting dial
2
- at "0" when sewing with tapes.
- at desirable number for contraction when
sewing with elastics.
NOTE:
Contraction will be increased with larger number.
7. Make test-sewing and adjust thread tensions.
Example of proper sewing seam:

NOTE:
Thread tensions are similar to normal
overedging when sewing with tapes.
It is recommendable to have stronger tensions
for the lower looper and the upper looper for
beautiful finish.
It is advisable to make trial sewing on each

and adjust the clearance
between folded edge needle so that it becomes
1 mm to 1.5 mm (3/64 to 1/16 inch).
4.
Place the pearl through the guide just front of

Test-sewing
1. Sew turning handwheel by hand until the pearl
comes through the tunnel.
2.
Sew at slow speed while guiding the strand of
pearls and fabric by hand.
3.
Tie both ends of thread at the beginning and
the end.
NOTE:
Thread tension is easy to loosen especially for
