Seaming Knit Fabrics:
Differential Feed
Thread the serger for a 4-thread overlock stitch, using regular serger
thread in the needles and Woolly Nylon in the loopers.
Set all thread tensions at usual 4-thread overlock settings.
Using a fabric marker, divide the fabric in half along a 6” side.
With right sides together and a ¼” seam allowance, serge to the mark
on the fabric.
Without removing the fabric from under the presser foot, notice the
“ripple” effect where the fabric has stretched.
Locate the differential feed dial on the serger. Adjust to 1.5.
Seam the jersey to the end of the fabric.
Remove the fabric from under the presser foot and observe the
decreased “rippling”.
Return the differential feed dial to normal setting (N).
Trim and mount the sample.
