10 – 2 Three – thread narrow rolled edge
Use three – thread rolled edging to provide a secure seam or
decorative edge on light to medium weight fabrics.
1.
Remove the stitch finger. (See steps 3 ~ 5, page 25).
2.
Remove left needle; use right needle only.
3. Adjust tension by rotating lower looper tension knob about 3
numbers higher than it is normally set for three – thread
sewing.
The tension adjustment tightens the lower looper thread, causing
the edge of the fabric to roll around the stitch finger. The upper
looper thread then wraps the fabric edge. Sew a test sample first
to determine if edge of fabric is sufficiently rolled. If not, continue to
tighten until desired effect is achieved. Record tension setting on
chart (page 35).
10 – 3 Two – thread narrow rolled edge
A two – thread narrow rolled edge is often preferred for hemming very soft fabrics which may otherwise develop undesired
stiffness with three – threads. It can also produce interesting “picot – like” effects on tricot and stretch knit fabrics if the
stitch is lengthened to “4”.
1.
Remove the stitch finger. (See steps 3 ~ 5, page 25).
2.
Remove left needle; use right needle only.
3.
Set the machine for two – thread sewing (page 21).
4.
Adjust the needle tension by rotating knob to “6”.
This tension adjustment tightens the needle thread and causes the lower looper thread to roll around the stitch finger,
wrapping the fabric edge. If “6” does not create a tight enough roll, turn to a higher number. If it is too tight, or the thread
breaks, turn to a lower number. Sew a test sample, and record tension settings on chart. (Page 35)
