Roll hemmer
Be sure to turn power switch OFF.
Switch the machine off (power switch"O")
The roll hemmer is built-in to the sewing machine. The fabric edge is
automatically rolled and oversewn. The result is a very fine and narrow
edge finishing.
Preparation for roll hemming
1. Remove the left-hand needle and thread the machine as for
3-thread overlocking.
2. Set the lower knife adjusting knob at "1 - 2".
3. Turn the overlocking width selection knob toward you to align with
the red marking in front of the throat plate.
4. Set the stitch length adjusting knob at "1 - 1.5".
* Adjust the thread tensions as desired. Tighten the lower looper
tension.
(A): Rolled hem
Rolled hemming stitch sews the fabric edge with the upper looper
thread.
(B): Narrow overlock stitch
Narrow overlock stitch is to sew normal overlock stitches of which cut-
ting width is narrower than usual.
Standard thread tension list for roll hemming
hem, narrow overlock stitch)
◦ Thread tension slightly differs depending on the types of the
fabric and thread.
◦ Use the woolly nylon thread or thinner thread for roll hem-
ming to attain the beautiful finish.
◦ Use the thin spun thread thinner than #80.
◦ Woolly nylon thread can be used only for the upper looper.
