Differential Feed
Your baby lock serger is equipped with differential feed.
The set 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 dial is set above "N", the front feed dog will feed
more fabrics than the back. This is because the front feed
dog moves at a greater distance than the back feed dogs.
As a result, the fabric becomes compressed or eased, as
the diagram on the front cover indicates. This action ca-
neliminate 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 desi-
red 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, active wear, and can be used to cre-
ate a lettuce edge. (see page 25).
