Sewing
Rolled hem with foot No. 7
Use the rolled hem foot to fi nish the edges of blouses, scarves, or ruffl es
without having to iron the edges beforehand. Hemming prevents the
edges from fraying and produces a neat and durable edge fi nish.
• Double-fold the fabric edge (about 1/8 inch / 2 mm per fold).
• Place the folded fabric edge under the rolled hem foot and sew a
few stitches to secure.
• Turn the hand wheel towards you until the needle is at its lowest
point. Raise the presser foot and slide the fabric into the scroll of
the foot.
• Lower the presser foot and while sewing, guide the fabric edge
evenly into the foot. When roll-hemming, make sure the raw edge
of the fabric butts against the left edge of the rolled hem foot open-
ing. Ensure the fabric does not run underneath the right side of the
presser foot.
Tip: A narrow zigzag stitch also makes a nice rolled hem on lighter stretch
fabrics such as lingerie nylon.
Twin needle
When you touch the twin needle icon the machine allows you to
specify the width of the twin needle you will use. The stitch width will
automatically be reduced to prevent needle breakage and allow you to
sew decorative stitches with a twin needle.
1. Touch twin needle icon and a popup appears. Touch ON to activate
the function.
2. Touch the +/- icon to specify your twin needle width (A). The stitch
is shown as it will sew.
3. Touch OK to close the window and save your settings or ESC, to
continue without saving any settings.
This function must be deactivated when you remove the needle from
the machine. It remains active even after the stitch has been changed,
including after the machine has been turned off and on again.
To deactivate the twin needle function, touch the twin needle icon,
touch ON to deactivate the function. The icon becomes light green
again.
Twin needle sewing
You can achieve beautiful effects when embroidering with the twin
needle. These embroideries turn out best with a needle width of
1.6 - 3 mm. Twin-needle embroidery is particularly effective if you
use embroidery threads in matching colors. If you wish to sew with
the twin needle, touch the twin needle icon. The stitch width is
automatically reduced and not displaced to the right or to the left if a
stitch is asymmetrical. In this way the needle is prevented from hitting
the presser foot.
See page 2:15 for threading a twin needle.
Sewing Maxi stitches with a twin needle
If the icon for the twin needle program is active when sewing Maxi
stitches, you can use the twin needle for a decorative effect. However,
you should only use a twin needle with a width of 1.6mm or 1.8mm,
even if a twin needle width up to 6mm can be selected in the program.
