The rolled edge setting is used to achieve the narrowest stitch possible (1.5mm) on your Baby
Lock serger. The stitch is suitable for seaming sheer and lightweight fabrics and for edging and

hemming lightweight fabrics.

3-Thread Rolled Edge

1. Remove the left needle and corresponding thread.

2. Clear the stitch fingers.
3. Turn the stitch length adjusting dial counter-clockwise into
D
the rolled hem range. Set the desired stitch length within
this range. (fig. A)
G
4. Turn the stitch width dial until the "M" lines up with the
indicator. (fig. B)
I
5. Increase the lower looper tension. (fig. C)
N
The tension adjustment tightens the lower looper thread,
causing the fabric edge to roll around the stitch finger.
G
The upper looper thread then wraps the fabric edge. The
lower looper thread will be nearly invisible on the back side of
the stitch formation. Sew a test sample first to determine if
the fabric edge is sufficiently rolled. If not, increasing lower
looper tension and decreasing upper looper tension both may
help to create the desired effect.
Record tension settings on the chart on the inside back cover.
Note: If a narrow unrolled edge is desired, follow step 1
through 4 above, leaving tensions set as for standard
3-thread serging with the right needle.
