Differential Feed - Bernina Serger User Manual

Knit ribbing, three pieces, 3" x 6" each
Fabric:
80/12 Universal
Needle:
4 cones of serger thread (blue, red, green, yellow)
Thread:
Standard
Presser Foot:
4-thread overlock
Stitch:
Thread the serger for a 4-thread overlock stitch using
thread colors to match the color-coded threading path
on the serger. Adjust all thread tension settings as
indicated below.
Set the cutting width as needed and set the stitch length
to 2.5mm.
With differential set at N, serge two of the ribbing pieces
together along one 6" edge. If the fabric is stretchy enough
you will have a wavy edge.
Adjust the differential to 2.0. Stitch along the 6" side,
serging the remaining ribbing to the other side of the piece,
trimming slightly. With differential at a higher setting, the
wavy edge should be eliminated.
Mark the differential settings on the fabric sample.
Return the differential feed setting to N (normal).
