Differential Feed

Your Baby Lock serger is equipped with differential feed.
The sets of feed dogs work independently in order to ensure
smooth sewing on all fabrics. (fig. A)
When the differential feed adjusting lever, located at the
machine's right, front edge is set on "N" for normal feeding,
the feed dogs move the same distance. This is the setting to
use for most fabrics and applications. (fig. B)
When the differential feed lever is set above "N", the front feed
dog will feed more fabric than the back. This is because the
front feed dog moves a greater distance than the back feed
dog. As a result, the fabric becomes compressed or eased,
as the diagram on the front cover indicates. This action can
eliminate wavy seams in stretchy fabrics or those cut on the
bias grain.
At the maximum setting of 2.0 (fig. C), the differential feed
can gather a lightweight fabric to nearly double fullness.
(fig. D) The front feed dog is actually feeding in twice as
much fabric as the back feed dog is feeding out.
To maximize the gathering effects, use the longest stitch
length setting. Fabric weight will affect the gathering. Test
stitch for desired results.
When the differential feed lever is set below "N" (fig. E), the
front feed dog moves less distance than the back feed dog.
This adjustment stretches the fabric slightly as it is sewn,
pulling it taut as it enters the needle. The lower settings
prevent puckers on lightweight fabric (fig. F), add more
stretch to swim wear and active wear, and can be used to
create a lettuce edge. (see page 26).
