Thread
Size
Pin tucks and narrow cording are made with a No. 50 embroidery thread, wider cording with sewing silk in the needle
and on the bobbin.
Set the machine for a medium stitch length (about 4).
Place a spool of thread on each of the two spool pins. Pass both thread ends through both thread retainer openings 2,
as Illustrated on page 15. Lead one thread between the rear and center tension discs, and the other between the center
and front tension discs of upper tension 3. Raise take-up lever 4 to its highest position and pass both threads through
the hole at its end. Pull threads into slot 5 and thread each needle from front to back.
The bobbin thread is drawn up as instructed on page 16. To do this, hold both needle threads in your left hand.
Thread Tension
Slightly increase the bobbin thread tension, and increase or decrease the
needle thread tension depending on the type of fabric used. If the tension
has been set correctly, the bobbin thread should appear as a faint zigzag
line on the other side.
Filled Cording
If you want to make cording in filmy fabrics or render your cording more
prominent, Pfaff recommends that you insert a filler cord, Its thickness
depends on the cording size you want.
Remove the bed slide and pass the filler cord through hole g from below
(see ill, on page 41). Lay the end of the filler cord back under the cording
foot (together with the needle and bobbin thread ends). Pull a filler cord
forward under the bed slide and place the ball in your lap.
